1.  Elevated Risk for HIV Infection among Men Who Have Sex with Men in Low- and Middle-Income Countries 2000–2006: A Systematic Review 
PLoS Medicine  2007;4(12):e339.
Background
Recent reports of high HIV infection rates among men who have sex with men (MSM) from Asia, Africa, Latin America, and the former Soviet Union (FSU) suggest high levels of HIV transmission among MSM in low- and middle-income countries. To investigate the global epidemic of HIV among MSM and the relationship of MSM outbreaks to general populations, we conducted a comprehensive review of HIV studies among MSM in low- and middle-income countries and performed a meta-analysis of reported MSM and reproductive-age adult HIV prevalence data.
Methods and Findings
A comprehensive review of the literature was conducted using systematic methodology. Data regarding HIV prevalence and total sample size was sequestered from each of the studies that met inclusion criteria and aggregate values for each country were calculated. Pooled odds ratio (OR) estimates were stratified by factors including HIV prevalence of the country, Joint United Nations Programme on HIV/AIDS (UNAIDS)–classified level of HIV epidemic, geographic region, and whether or not injection drug users (IDUs) played a significant role in given epidemic. Pooled ORs were stratified by prevalence level; very low-prevalence countries had an overall MSM OR of 58.4 (95% CI 56.3–60.6); low-prevalence countries, 14.4 (95% CI 13.8–14.9); and medium- to high-prevalence countries, 9.6 (95% CI 9.0–10.2). Significant differences in ORs for HIV infection among MSM in were seen when comparing low- and middle-income countries; low-income countries had an OR of 7.8 (95% CI 7.2–8.4), whereas middle-income countries had an OR of 23.4 (95% CI 22.8–24.0). Stratifying the pooled ORs by whether the country had a substantial component of IDU spread resulted in an OR of 12.8 (95% CI 12.3–13.4) in countries where IDU transmission was prevalent, and 24.4 (95% CI 23.7–25.2) where it was not. By region, the OR for MSM in the Americas was 33.3 (95% CI 32.3–34.2); 18.7 (95% CI 17.7–19.7) for Asia; 3.8 (95% CI 3.3–4.3) for Africa; and 1.3 (95% CI 1.1–1.6) for the low- and middle-income countries of Europe.
Conclusions
MSM have a markedly greater risk of being infected with HIV compared with general population samples from low- and middle-income countries in the Americas, Asia, and Africa. ORs for HIV infection in MSM are elevated across prevalence levels by country and decrease as general population prevalence increases, but remain 9-fold higher in medium–high prevalence settings. MSM from low- and middle-income countries are in urgent need of prevention and care, and appear to be both understudied and underserved.
From a systematic review, Chris Beyrer and colleagues conclude that men who have sex with men in the Americas, Asia, and Africa have a markedly greater risk of being HIV-infected than does the general population.
Editors' Summary
Background.
AIDS (acquired immunodeficiency syndrome) first emerged in the early 1980s among gay men living in New York and California. But, as the disease rapidly spread around the world, it became clear that AIDS also affected heterosexual men and women. Now, a quarter of a century later, 40 million people are infected with human immunodeficiency virus (HIV), the organism that causes AIDS. HIV is most often spread by having unprotected sex with an infected partner and in sub-Saharan Africa, the region most badly hit by HIV/AIDS, heterosexual transmission predominates. However, globally, 5%–10% of all HIV infections are thought to be in men who have sex with men (MSM, a term that encompasses gay, bisexual, transgendered, and heterosexual men who sometimes have sex with men), and in several high-income countries, including the US, male-to-male sexual contact remains the most important HIV transmission route.
Why Was This Study Done?
In the US, the MSM population is visible and there is considerable awareness about the risks of HIV transmission associated with sex between men. In many other countries, MSM are much less visible. They remain invisible because they fear discrimination, stigmatization (being considered socially unacceptable), or arrest—sex between men is illegal in 85 countries. Consequently, MSM are often under-represented in HIV surveillance systems and in prevention and care programs. If the AIDS epidemic is going to be halted, much more needs to be known about HIV prevalence (the proportion of the population that is infected) among MSM. In this study, the researchers have done a systematic review (a type of research where the results of existing studies are brought together) on published reports of HIV prevalence among MSM in low- and middle-income countries to get a better picture of the global epidemic of HIV in this population.
What Did the Researchers Do and Find?
The researchers found 83 published studies that reported HIV prevalence in 38 low- and middle-income countries in Asia, Africa, the Americas, and Eastern Europe. When the results were pooled—in what statisticians call a meta-analysis—MSM were found to have a 19.3-times greater chance of being infected with HIV than the general population. This is described as a pooled odds ratio (OR) of 19.3. The researchers also did several subgroup analyses where they asked whether factors such as injection drug use (another risk factor for HIV transmission), per capita income, geographical region, or the HIV prevalence in the general population were associated with differential risk (increase in odds) of HIV infection compared to the general population. They found, for example, that in countries where the prevalence of HIV in the general population was very low (less than 1 adult in 1,000 infected) the pooled OR for MSM compared to the general population was 58.4; where it was high (more than 1 adult in 20 infected), the pooled OR for MSM was 9.6.
What Do These Findings Mean?
These findings indicate that MSM living in low- to middle-income countries have a greater risk of HIV infection than the general populations of these countries. The subgroup analyses indicate that the high HIV prevalence among MSM is not limited to any one region or income level or to countries with any specific HIV prevalence or injection drug use level. Although the small number and design of the studies included in the meta-analysis may affect the numerical accuracy of these findings, the clear trend toward a higher HIV prevalence of among MSM suggests that HIV surveillance efforts should be expanded to include MSM in those countries where they are currently ignored. Efforts should also be made to include MSM in HIV prevention programs and to improve the efficacy of these programs by investigating the cultural, behavioral, social, and public policy factors that underlie the high HIV prevalence among MSM. By increasing surveillance, research, and prevention among MSM in low- to middle-income countries, it should be possible to curb HIV transmission in this marginalized population and reduce the global burden of HIV.

2.  Prevalence of Consensual Male–Male Sex and Sexual Violence, and Associations with HIV in South Africa: A Population-Based Cross-Sectional Study 
PLoS Medicine  2013;10(6):e1001472.
Using a method that offered complete privacy to participants, Rachel Jewkes and colleagues conducted a survey among South African men about their lifetime same-sex experiences.
Please see later in the article for the Editors' Summary
Background
In sub-Saharan Africa the population prevalence of men who have sex with men (MSM) is unknown, as is the population prevalence of male-on-male sexual violence, and whether male-on-male sexual violence may relate to HIV risk. This paper describes lifetime prevalence of consensual male–male sexual behavior and male-on-male sexual violence (victimization and perpetration) in two South African provinces, socio-demographic factors associated with these experiences, and associations with HIV serostatus.
Methods and Findings
In a cross-sectional study conducted in 2008, men aged 18–49 y from randomly selected households in the Eastern Cape and KwaZulu-Natal provinces provided anonymous survey data and dried blood spots for HIV serostatus assessment. Interviews were completed in 1,737 of 2,298 (75.6%) of enumerated and eligible households. From these households, 1,705 men (97.1%) provided data on lifetime history of same-sex experiences, and 1,220 (70.2%) also provided dried blood spots for HIV testing. 5.4% (n = 92) of participants reported a lifetime history of any consensual sexual activity with another man; 9.6% (n = 164) reported any sexual victimization by a man, and 3.0% (n = 51) reported perpetrating sexual violence against another man. 85.0% (n = 79) of men with a history of consensual sex with men reported having a current female partner, and 27.7% (n = 26) reported having a current male partner. Of the latter, 80.6% (n = 21/26) also reported having a female partner. Men reporting a history of consensual male–male sexual behavior are more likely to have been a victim of male-on-male sexual violence (adjusted odds ratio [aOR] = 7.24; 95% CI 4.26–12.3), and to have perpetrated sexual violence against another man (aOR = 3.10; 95% CI 1.22–7.90). Men reporting consensual oral/anal sex with a man were more likely to be HIV+ than men with no such history (aOR = 3.11; 95% CI 1.24–7.80). Men who had raped a man were more likely to be HIV+ than non-perpetrators (aOR = 3.58; 95% CI 1.17–10.9).
Conclusions
In this sample, one in 20 men (5.4%) reported lifetime consensual sexual contact with a man, while about one in ten (9.6%) reported experience of male-on-male sexual violence victimization. Men who reported having had sex with men were more likely to be HIV+, as were men who reported perpetrating sexual violence towards other men. Whilst there was no direct measure of male–female concurrency (having overlapping sexual relationships with men and women), the data suggest that this may have been common. These findings suggest that HIV prevention messages regarding male–male sex in South Africa should be mainstreamed with prevention messages for the general population, and sexual health interventions and HIV prevention interventions for South African men should explicitly address male-on-male sexual violence.

Editors' Summary
Background
AIDS first emerged in the early 1980s among gay men living in the US, but it soon became clear that AIDS also infects heterosexual men and women. Now, three decades on, globally, 34 million people (two-thirds of whom live in sub-Saharan Africa and half of whom are women) are infected with HIV, the virus that causes AIDS, and 2.5 million people become infected every year. HIV is most often spread by having unprotected sex with an infected partner, and most sexual transmission of HIV now occurs during heterosexual sex. However, 5%–10% of all new HIV infections still occur in men who have sex with men (MSM; homosexual, bisexual, and transgender men, and heterosexual men who sometimes have consensual sex with men). Moreover, in the concentrated HIV epidemics of high-income countries (epidemics in which the prevalence of HIV infection is more than 5% in at-risk populations such as sex workers but less than 1% in the general population), male-to-male sexual contact remains the most important transmission route, and MSM often have a higher prevalence of HIV infection than heterosexual men.
Why Was This Study Done?
By contrast to high-income countries, HIV epidemics in sub-Saharan Africa are generalized—the prevalence of HIV infection is 1% or more in the general population. Because male-to-male sexual behavior is criminalized in many African countries and because homosexuality is widely stigmatized, little is known about the prevalence of consensual male–male sexual behavior in sub-Saharan Africa. This information and a better understanding of male–female sexual concurrency (having overlapping sexual relationships with men and women) and of how male-to-male transmission contributes to generalized HIV epidemics is needed to inform the design of HIV prevention strategies for use in sub-Saharan Africa. In addition, very little is known about male-on-male sexual violence. Such violence is potentially important to study because we know that male-on-female violence is associated with increased HIV risk for both victims and perpetrators. In this cross-sectional study (an investigation that measures population characteristics at a single time point), the researchers use data from a population-based household survey to investigate the lifetime prevalence of consensual male–male sexual behavior and male-on-male sexual violence (victimization and perpetration) among men in South Africa and the association of these experiences with HIV infection.
What Did the Researchers Do and Find?
About 1,700 adult men from randomly selected households in the Eastern Cape and KwaZulu-Natal provinces of South Africa self-completed a survey that included questions about their lifetime history of same-sex experiences using audio-enhanced personal digital assistants, a data collection method that provided a totally private and anonymous environment for the disclosure of illegal and stigmatized behavior; 1,220 of them also provided dried blood spots for HIV testing. Ninety-two men (5.4% of the participants) reported consensual sexual activity (for example, anal or oral sex) with another man at some time during their life; 9.6% of the men reported that they had been forced to have sex with another man (sexual victimization), and 3% reported that they had perpetrated sexual violence against another man. Most of the men who reported consensual sex with men, including those with current male partners, reported that they had a current female partner. Men with a history of consensual male–male sexual behavior were more likely to have been a victim or perpetrator of male-on-male sexual violence than men without a history of such experiences. Finally, men who reported consensual oral or anal sex with a man were more likely to be HIV+ than men without such a history, and perpetrators of male-on-male sexual violence were more likely to be HIV+ than non-perpetrators.
What Do These Findings Mean?
These findings provide new information about male–male sexual behaviors, male-on-male sexual violence, male–female concurrency, and HIV prevalence among men in two South African provinces. The precision of these findings is likely to be affected by the small numbers of men reporting a history of consensual male–male sexual behavior and of male-on-male sexual violence. Importantly, because the study was cross-sectional, these findings cannot indicate whether the association between consensual male–male sexual behaviors and increased risk of male-on-male sexual violence is causal. Moreover, these findings may not be generalizable to other regions of South Africa or to other African countries. Nevertheless, these findings suggest that information about the risks of male–male sexual behaviors should be included in HIV prevention strategies targeted at the general population in South Africa and that HIV prevention interventions for South African men should explicitly address male-on-male sexual violence. Similar HIV prevention strategies may also be suitable for other African countries, but are likely to succeed only in countries that have, like South Africa, decriminalized consensual homosexual behavior.

3.  Sexual health of ethnic minority MSM in Britain (MESH project): design and methods 
BMC Public Health  2010;10:419.
Background
Men who have sex with men (MSM) remain the group most at risk of acquiring HIV infection in Britain. HIV prevalence appears to vary widely between MSM from different ethnic minority groups in this country for reasons that are not fully understood. The aim of the MESH project was to examine in detail the sexual health of ethnic minority MSM living in Britain.
Methods/Design
The main objectives of the MESH project were to explore among ethnic minority MSM living in Britain: (i) sexual risk behaviour and HIV prevalence; (ii) their experience of stigma and discrimination; (iii) disclosure of sexuality; (iv) use of, and satisfaction with sexual health services; (v) the extent to which sexual health services (for treatment and prevention) are aware of the needs of ethnic minority MSM.
The research was conducted between 2006 and 2008 in four national samples: (i) ethnic minority MSM living in Britain; (ii) a comparison group of white British MSM living in Britain; (iii) NHS sexual health clinic staff in 15 British towns and cities with significant ethnic minority communities and; (iv) sexual health promotion/HIV prevention service providers. We also recruited men from two "key migrant" groups living in Britain: MSM born in Central or Eastern Europe and MSM born in Central or South America.
Internet-based quantitative and qualitative research methods were used. Ethnic minority MSM were recruited through advertisements on websites, in community venues, via informal networks and in sexual health clinics. White and "key migrant" MSM were recruited mostly through Gaydar, one of the most popular dating sites used by gay men in Britain. MSM who agreed to take part completed a questionnaire online. Ethnic minority MSM who completed the online questionnaire were asked if they would be willing to take part in an online qualitative interview using email.
Service providers were identified through the British Association of Sexual Health and HIV (BASHH) and the Terrence Higgins Trust (THT) CHAPS partnerships. Staff who agreed to take part were asked to complete a questionnaire online.
The online survey was completed by 1241 ethnic minority MSM, 416 men born in South and Central America or Central and Eastern Europe, and 13,717 white British MSM; 67 ethnic minority MSM took part in the online qualitative interview. In addition 364 people working in sexual health clinics and 124 health promotion workers from around Britain completed an online questionnaire.
Discussion
The findings from this study will improve our understanding of the sexual health and needs of ethnic minority MSM in Britain.

4.  An Intervention to Reduce HIV Risk Behavior of Substance-Using Men Who Have Sex with Men: A Two-Group Randomized Trial with a Nonrandomized Third Group 
PLoS Medicine  2010;7(8):e1000329.
In a randomized trial of a behavioral intervention among substance-using men who have sex with men, aimed at reducing sexual risk behavior, Mansergh and colleagues fail to find evidence of a reduction in risk from the intervention.
Background
Substance use during sex is associated with sexual risk behavior among men who have sex with men (MSM), and MSM continue to be the group at highest risk for incident HIV in the United States. The objective of this study is to test the efficacy of a group-based, cognitive-behavioral intervention to reduce risk behavior of substance-using MSM, compared to a randomized attention-control group and a nonrandomized standard HIV-testing group.
Methods and Findings
Participants (n = 1,686) were enrolled in Chicago, Los Angeles, New York City, and San Francisco and randomized to a cognitive-behavioral intervention or attention-control comparison. The nonrandomized group received standard HIV counseling and testing. Intervention group participants received six 2-h group sessions focused on reducing substance use and sexual risk behavior. Attention-control group participants received six 2-h group sessions of videos and discussion of MSM community issues unrelated to substance use, sexual risk, and HIV/AIDS. All three groups received HIV counseling and testing at baseline. The sample reported high-risk behavior during the past 3 mo prior to their baseline visit: 67% reported unprotected anal sex, and 77% reported substance use during their most recent anal sex encounter with a nonprimary partner. The three groups significantly (p<0.05) reduced risk behavior (e.g., unprotected anal sex reduced by 32% at 12-mo follow-up), but were not different (p>0.05) from each other at 3-, 6-, and 12-mo follow-up. Outcomes for the 2-arm comparisons were not significantly different at 12-mo follow-up (e.g., unprotected anal sex, odds ratio = 1.14, confidence interval = 0.86–1.51), nor at earlier time points. Similar results were found for each outcome variable in both 2- and 3-arm comparisons.
Conclusions
These results for reducing sexual risk behavior of substance-using MSM are consistent with results of intervention trials for other populations, which collectively suggest critical challenges for the field of HIV behavioral interventions. Several mechanisms may contribute to statistically indistinguishable reductions in risk outcomes by trial group. More explicit debate is needed in the behavioral intervention field about appropriate scientific designs and methods. As HIV prevention increasingly competes for behavior-change attention alongside other “chronic” diseases and mental health issues, new approaches may better resonate with at-risk groups.

Editors' Summary
Background
AIDS first emerged in the early 1980s among gay men living in the US. As the disease spread around the world, it became clear that AIDS also affects heterosexual men and women. Now, three decades on, more than 30 million people are infected with HIV, the virus that causes AIDS. HIV is most often spread by having unprotected sex with an infected partner and, globally, most sexual transmission of HIV now occurs during heterosexual sex. However, 5%–10% of all new HIV infections still occur in men who have sex with men (MSM, a term that encompasses gay, bisexual, transgendered, and heterosexual men who sometimes have sex with men) and, in several high-income countries, male-to-male sexual contact remains the most important HIV transmission route. In the US, for example, more than half of the approximately 50,000 people who become infected with HIV every year do so through male-to-male sexual contact.
Why Was This Study Done?
In countries where MSM are the group at highest risk of HIV infection, any intervention that reduces HIV transmission in MSM should have a major effect on the overall HIV infection rate. Among MSM, sexual behaviors that increase the risk of HIV infection (for example, not using a condom, having anal sex, having sex with a partner of unknown HIV status, and having sex with many partners) are associated with the use of alcohol and noninjection drugs (for example, inhaled amyl nitrite or poppers) during or shortly before sexual encounters. In this study (Project MIX), the researchers investigate whether a group-based behavioral intervention reduces sexual risk behavior in substance-using MSM.
What Did the Researchers Do and Find?
The researchers recruited substance-using MSM from four US cities who had had risky sex at least once in the past 6 months. Participants were randomized to a cognitive-behavioral intervention or to an attention-control group; a third, nonrandomized group of MSM formed a standard HIV counseling and testing only group. All the groups had HIV counseling and testing at the start of the study and completed a questionnaire about their substance use and sexual risk behavior during their most recent anal sex encounter. The cognitive-behavior group then received six weekly 2-hour group sessions focused on reducing substance use and sexual risk behavior by helping the men change their thinking (cognition) and behavior regarding sexual risk taking. The attention-control group received six group sessions about general MSM issues such as relationships, excluding discussion of substance use, and sexual risk behavior. The participants in both of these groups completed the questionnaire about their substance use and sexual risk behavior again at 3, 6, and 12 months after the group sessions; the participants in the standard HIV counseling and testing group completed the questionnaire again about 5 months after completing the first questionnaire (to control for the time taken by the other two groups to complete the intervention). At baseline, about 67% of the participants reported unprotected anal sex and 77% reported substance use during their most recent anal sex encounter with a nonprimary partner. At the 3-month follow-up, the incidence of sexual risk behavior had fallen to about 43% in all three groups; the incidence of substance use during sex had fallen to about 50%. Risk taking and substance use remained at these levels in the intervention and attention-control groups at the later follow-up time points.
What Do These Findings Mean?
These findings suggest that this cognitive-behavioral intervention is no better at reducing sexual risk taking among substance-using MSM than is an unrelated video-discussion group or standard HIV counseling and testing. One explanation for this negative result might be that brief counseling is especially effective with people who are ready for a change such as MSM willing to enroll in an intervention trial of this type. Alternatively, just being in the trial might have encouraged all the participants to self-report reduced risk behavior. Thus, alternative scientific designs and methods might be needed to find behavioral interventions that can effectively reduce HIV transmission among substance-using MSM and other people at high risk of HIV infection. Importantly, however, these findings raise the question of whether more extensive, multilevel interventions or broader lifestyle and positive health approaches (rather than single-level or single-subject behavioral interventions) might be needed to reduce sexual risk behavior among substance-using MSM.

5.  Associations between Intimate Partner Violence and Health among Men Who Have Sex with Men: A Systematic Review and Meta-Analysis 
PLoS Medicine  2014;11(3):e1001609.
Ana Maria Buller and colleagues review 19 studies and estimate the associations between the experience and perpetration of intimate partner violence and various health conditions and sexual risk behaviors among men who have sex with men.
Please see later in the article for the Editors' Summary
Background
Intimate partner violence (IPV) among men who have sex with men (MSM) is a significant problem. Little is known about the association between IPV and health for MSM. We aimed to estimate the association between experience and perpetration of IPV, and various health conditions and sexual risk behaviours among MSM.
Methods and Findings
We searched 13 electronic databases up to 23 October 2013 to identify research studies reporting the odds of health conditions or sexual risk behaviours for MSM experiencing or perpetrating IPV. Nineteen studies with 13,797 participants were included in the review. Random effects meta-analyses were performed to estimate pooled odds ratios (ORs). Exposure to IPV as a victim was associated with increased odds of substance use (OR = 1.88, 95% CIOR 1.59–2.22, I2 = 46.9%, 95% CII2 0%–78%), being HIV positive (OR = 1.46, 95% CIOR 1.26–1.69, I2 = 0.0%, 95% CII2 0%–62%), reporting depressive symptoms (OR = 1.52, 95% CIOR 1.24–1.86, I2 = 9.9%, 95% CII2 0%–91%), and engagement in unprotected anal sex (OR = 1.72, 95% CIOR 1.44–2.05, I2 = 0.0%, 95% CII2 0%–68%). Perpetration of IPV was associated with increased odds of substance use (OR = 1.99, 95% CIOR 1.33–2.99, I2 = 73.1%). These results should be interpreted with caution because of methodological weaknesses such as the lack of validated tools to measure IPV in this population and the diversity of recall periods and key outcomes in the identified studies.
Conclusions
MSM who are victims of IPV are more likely to engage in substance use, suffer from depressive symptoms, be HIV positive, and engage in unprotected anal sex. MSM who perpetrate IPV are more likely to engage in substance use. Our results highlight the need for research into effective interventions to prevent IPV in MSM, as well as the importance of providing health care professionals with training in how to address issues of IPV among MSM and the need to raise awareness of local and national support services.

Editors' Summary
Background
Intimate partner violence (IPV, also called domestic violence) is a common and widespread problem. Globally, nearly a third of women are affected by IPV at some time in their life, but the prevalence of IPV (the proportion of the population affected by IPV) varies widely between countries. In central sub-Saharan Africa, for example, nearly two-thirds of women experience IPV during their lifetime, whereas in East Asia only one-sixth of women are affected. IPV is defined as physical, sexual, or emotional harm that is perpetrated on an individual by a current or former partner or spouse. Physical violence includes hitting, kicking, and other types of physical force; sexual violence means forcing a partner to take part in a sex act when the partner does not consent; and emotional abuse includes threatening a partner by, for example, stalking them or preventing them from seeing their family. The adverse effects of IPV for women include physical injury, depression and suicidal behaviour, and sexual and reproductive health problems such as HIV infection and unwanted pregnancies.
Why Was This Study Done?
IPV affects men as well as women. Men can be subjected to IPV either by a female partner or by a male partner in the case of men who have sex with men (MSM, a term that encompasses homosexual, bisexual, and transgender men, and heterosexual men who sometimes have sex with men). Recent reviews suggest that the prevalence of IPV in same-sex couples is as high as the prevalence of IPV for women in opposite-sex relationships: reported lifetime prevalences of IPV in homosexual male relationships range between 15.4% and 51%. Little is known, however, about the adverse health effects of IPV on MSM. It is important to understand how IPV affects the health of MSM so that appropriate services and interventions can be provided to support MSM who experience IPV. In this systematic review (a study that identifies all the research on a given topic using predefined criteria) and meta-analysis (a study that combines the results of several studies using statistical methods), the researchers investigate the associations between the experience and perpetration of IPV and various health conditions and sexual risk behaviours among MSM.
What Did the Researchers Do and Find?
The researchers identified 19 studies that investigated associations between IPV and various health conditions or sexual risk behaviours (for example, unprotected anal sex, a risk factor for HIV infection) among MSM. The associations were expressed as odds ratios (ORs); an OR represents the odds (chances) that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure. The researchers estimated pooled ORs from the data in the individual studies using meta-analysis. The pooled lifetime prevalence of experiencing any IPV (which was measured in six studies) was 48%. Exposure to IPV as a victim was associated with an increased risk of substance (alcohol or drug) use (OR = 1.88, data from nine studies), reporting depressive symptoms (OR = 1.52, data from three studies), being HIV positive (OR = 1.46, data from ten studies), and engagement in unprotected sex (OR = 1.72, data from eight studies). Perpetration of IPV was associated with an increased risk of substance abuse (OR = 1.99, data from six studies).
What Do These Findings Mean?
These findings suggest that MSM frequently experience IPV and that exposure to IPV is associated with several adverse health conditions and sexual risk behaviours. There were insufficient data to estimate the lifetime prevalence of IPV perpetration among MSM, but these findings also reveal an association between IPV perpetration and substance use. The accuracy of these findings is limited by heterogeneity (variability) between the studies included in the meta-analyses, by the design of these studies, and by the small number of studies. Despite these and other limitations, these findings highlight the need to undertake research to identify interventions to prevent IPV among MSM and to learn more about the health effects of IPV among MSM. They highlight the importance of health care professionals being aware that IPV is a problem for MSM and of training these professionals to assess MSM for IPV. Finally, these results highlight the need to improve the availability and effectiveness of support services to which health care professionals can refer MSM experiencing or perpetrating IPV.

6.  “They are human beings, they are Swazi”: intersecting stigmas and the positive health, dignity and prevention needs of HIV-positive men who have sex with men in Swaziland 
Journal of the International AIDS Society  2013;16(4Suppl 3):18749.
Introduction
Despite the knowledge that men who have sex with men (MSM) are more likely to be infected with HIV across settings, there has been little investigation of the experiences of MSM who are living with HIV in sub-Saharan Africa. Using the framework of positive health, dignity and prevention, we explored the experiences and HIV prevention, care and treatment needs of MSM who are living with HIV in Swaziland.
Methods
We conducted 40 in-depth interviews with 20 HIV-positive MSM, 16 interviews with key informants and three focus groups with MSM community members. Qualitative analysis was iterative and included debriefing sessions with a study staff, a stakeholders’ workshop and coding for key themes using Atlas.ti.
Results
The predominant theme was the significant and multiple forms of stigma and discrimination faced by MSM living with HIV in this setting due to both their sexual identity and HIV status. Dual stigma led to selective disclosure or lack of disclosure of both identities, and consequently a lack of social support for care-seeking and medication adherence. Perceived and experienced stigma from healthcare settings, particularly around sexual identity, also led to delayed care-seeking, travel to more distant clinics and missed opportunities for appropriate services. Participants described experiences of violence and lack of police protection as well as mental health challenges. Key informants, however, reflected on their duty to provide non-discriminatory services to all Swazis regardless of personal beliefs.
Conclusions
Intersectionality provides a framework for understanding the experiences of dual stigma and discrimination faced by MSM living with HIV in Swaziland and highlights how programmes and policies should consider the specific needs of this population when designing HIV prevention, care and treatment services. In Swaziland, the health sector should consider providing specialized training for healthcare providers, distributing condoms and lubricants and engaging MSM as peer outreach workers or expert clients. Interventions to reduce stigma, discrimination and violence against MSM and people living with HIV are also needed for both healthcare workers and the general population. Finally, research on experiences and needs of MSM living with HIV globally can help inform comprehensive HIV services for this population.

7.  The Safety of Adult Male Circumcision in HIV-Infected and Uninfected Men in Rakai, Uganda 
PLoS Medicine  2008;5(6):e116.
Background
The objective of the study was to compare rates of adverse events (AEs) related to male circumcision (MC) in HIV-positive and HIV-negative men in order to provide guidance for MC programs that may provide services to HIV-infected and uninfected men.
Methods and Findings
A total of 2,326 HIV-negative and 420 HIV-positive men (World Health Organization [WHO] stage I or II and CD4 counts > 350 cells/mm3) were circumcised in two separate but procedurally identical trials of MC for HIV and/or sexually transmitted infection prevention in rural Rakai, Uganda. Participants were followed at 1–2 d and 5–9 d, and at 4–6 wk, to assess surgery-related AEs, wound healing, and resumption of intercourse. AE risks and wound healing were compared in HIV-positive and HIV-negative men. Adjusted odds ratios (AdjORs) were estimated by multiple logistic regression, adjusting for baseline characteristics and postoperative resumption of sex. At enrollment, HIV-positive men were older, more likely to be married, reported more sexual partners, less condom use, and higher rates of sexually transmitted disease symptoms than HIV-negative men. Risks of moderate or severe AEs were 3.1/100 and 3.5/100 in HIV-positive and HIV-negative participants, respectively (AdjOR 0.91, 95% confidence interval [CI] 0.47–1.74). Infections were the most common AEs (2.6/100 in HIV-positive versus 3.0/100 in HIV-negative men). Risks of other complications were similar in the two groups. The proportion with completed healing by 6 wk postsurgery was 92.7% in HIV-positive men and 95.8% in HIV-negative men (p = 0.007). AEs were more common in men who resumed intercourse before wound healing compared to those who waited (AdjOR 1.56, 95% CI 1.05–2.33).
Conclusions
Overall, the safety of MC was comparable in asymptomatic HIV-positive and HIV-negative men, although healing was somewhat slower among the HIV infected. All men should be strongly counseled to refrain from intercourse until full wound healing is achieved.

Editors' Summary
Background
Worldwide over 33 million people are thought to be living with HIV, and in the absence of a vaccine, preventing its spread is a major health issue. The World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimate that 68% of 2.5 million new infections worldwide in 2007 took place in sub-Saharan Africa, where 76% of 2.1 million AIDS-related deaths also took place.
One of the principal means of person-to-person transmission of HIV is through sex without the protection of a condom. In parts of Africa, male circumcision is performed in infancy or childhood for religious or cultural reasons or is a traditional rite of passage that marks the transition from child to man. Three trials, in South Africa, Kenya, and Uganda, each found that circumcised men were around half as likely as uncircumcised men to contract HIV from HIV-positive female partners. After reviewing the results, WHO and UNAIDS issued joint advice that male circumcision should be promoted for preventing HIV infection in heterosexual men. As male circumcision does not provide complete protection against HIV infection, they advised that it should be promoted in addition to existing strategies of promoting condom use, abstinence, and a reduction in the number of sexual partners.
Why Was This Study Done?
Although earlier studies had shown that adult male circumcision, when performed in Africa under optimal conditions, is a safe procedure for HIV-negative men, it was not known whether it would also be a safe procedure for HIV-positive men. WHO guidelines recommend that HIV-positive men who request the procedure or have a medical need and no contraindications for it should be circumcised. Also, exclusion of HIV-positive men from circumcision programs may result in stigmatization of these men, and discourage participation by men who do not wish to be tested for HIV. Therefore, it is important to know whether the procedure is safe for HIV-positive men.
What Did the Researchers Do and Find?
The authors compared results from two separate clinical trials carried out with identical procedures in rural Rakai, Uganda. The first, which compared the effect of circumcision with no circumcision in HIV-negative men, was one of the three trials that persuaded the WHO and UNAIDS to promote male circumcision as an HIV prevention strategy. The second Rakai trial did the same comparison but in men who were HIV positive and without symptoms. In this present study, the authors used data from both trials to compare the likelihood of surgery-related complications following circumcision for HIV-negative and HIV-positive men.
The trials recruited men aged 15–49, who were randomly assigned to be circumcised either on enrollment or two years later and were followed up to monitor complications related to the procedure, such as infections, as well as wound healing and when the participant first had sex after the operation. Condom use was recorded at enrollment and six months after enrollment.
The researchers found that most complications were infrequent, mild, and comparable in both groups, with moderate-to-severe complications occurring in only 3%–4% of men in each group. However, delayed wound healing was more frequent in HIV-positive men. Complications were more likely among men who had sex before healing was complete; such men were more likely to be HIV-positive and/or married. Similarly, moderate or severe complications were more likely where men had symptoms of sexually transmitted disease at enrollment, although these were treated before surgery, and these men were more likely to be HIV-positive. Six months after enrollment, similar proportions of HIV-positive and HIV-negative men used condoms consistently, but HIV-positive men were more likely to report using condoms inconsistently than HIV-negative men. However, consistent use of a condom increased among the HIV-positive men compared to when they enrolled.
What Do these Findings Mean?
Circumcision in HIV-positive men without symptoms of AIDS has a low rate of complications, although healing is slower than in HIV-negative men. Because of the greater risk of complications if sex is resumed before full healing, both men and their women partners should be advised to have no sex for at least six weeks after the operation. A separately reported analysis from one of these studies found that women partners are more likely to become HIV infected by HIV-positive men who resume sex prior to complete wound healing. Therefore, for protection of both men and their female partners, it is essential to refrain from intercourse after circumcision until the wound has completely healed.
Because the study found no increased risk of surgical complications in HIV-positive men who undergo circumcision, it should not be necessary to screen men with no symptoms of HIV in future circumcision programs. This should reduce the complexity of implementing such programs and reduce any stigma resulting from exclusion, making it likely that more men will be willing to be circumcised. The rise in consistent condom use among HIV-positive men suggests that messages of safe sex are reaching an important target group and changing their behavior, and that circumcision does not make men less likely to use a condom.
The authors also noted that the rates of complications they observed were low compared with those following traditional circumcision procedures. Others have found that circumcision carried out under unsafe conditions has a high rate of complications. The authors of this study comment that the resources and standards of surgery during the trial represented best practice and that to attain similarly low rates of complications—and the confidence of men in the safety of the procedure—there is a need to ensure sufficient resources and high standards of training.

8.  HIV testing and self-reported HIV status in South African MSM: Results from a community-based survey 
Sexually transmitted infections  2008;84(6):425-429.
Objective
To investigate the characteristics of South African men who have sex with men (MSM) who (1) have been tested for HIV and (2) are HIV-positive.
Methods
Data were collected among 1045 MSM in community surveys using questionnaires which were administered either face-to-face, mail, or on the internet. The mean age of the men was 29.9 years. The racial distribution was as follows: 35.3% black, 17.0% coloured, 5.3% Indian, and 41.1% white.
Results
The proportion of MSM that were HIV-tested was 69.7%; having been tested was independently associated with being older, being more open about one's homosexuality, and being homosexually instead of bisexually attracted; black MSM, students, and MSM living in KwaZulu-Natal were less likely to have been tested. Of the 728 MSM who had ever been tested, 14.1% (n=103) reported to be HIV-positive (9.9% of the total sample). Being HIV-positive is independently associated with two factors: men who were positive were more likely to have a lower level of education and to know other persons who were living with HIV/AIDS; race was not independently associated with HIV status among those who had been tested.
Conclusions
The likelihood of having been tested for HIV seems to decrease with increasing social vulnerability. Racially, the distribution of HIV among MSM seems to differ from that of the general South African population, suggesting that while intertwined with the heterosexual epidemic, there is also an epidemic among South African MSM with specific dynamics. These findings suggest that in-depth research is urgently needed to address the lack of understanding of HIV testing practices and HIV prevalence in South African MSM.

9.  High HIV Prevalence among MSM in Jamaica is associated with Social Vulnerability and other Sexually Transmitted Infections 
The West Indian medical journal  2013;62(4):286-291.
Background
HIV prevalence among men who have sex with men (MSM) is thought to be high in Jamaica. The objective of this study was to estimate HIV prevalence and identify risk factors in order to improve prevention approaches.
Methods
With the help of influential MSM, an experienced research nurse approached MSM in four parishes to participate in a cross-sectional survey in 2007. MSM were interviewed and blood taken for HIV and syphilis tests, and urine taken for gonorrhoea, Chlamydia and Trichomonas testing using transcription-mediated amplification assays. A structured questionnaire was administered by the nurse.
Results
One third (65 of 201; 32%, 95% Confidence Interval (CI) 25.2% – 47.9%) of MSM were HIV positive. Prevalence of other sexually transmitted infections (STI) was: Chlamydia 11%, syphilis 6%, gonorrhea 3.5% and Trichomonas 0%. One third (34%) of MSM identified themselves as being homosexual, 64% as bisexual and 1.5% as heterosexual. HIV positive MSM were significantly more likely to have ever been told by a doctor that they had a STI (48% vs. 27%, OR 2.48 CI 1.21 – 5.04, p=0.01) and to be the receptive sexual partner at last sex (41% vs. 23%, OR 2.41 CI 1.21 – 4.71, p=0.008). MSM who were of low socio-economic status, ever homeless and victims of physical violence were twice as likely to be HIV positive. The majority (60%) of HIV positive MSM had not disclosed their status to their partner and over 50% were not comfortable disclosing their status to anyone.
Conclusions
The high HIV prevalence among MSM is an important factor driving the HIV epidemic in Jamaica. More effective ways need to be found to reduce the high prevalence of HIV among MSM including measures to reduce their social vulnerability, combat stigma and discrimination and empower them to practice safe sex.

10.  HIV prevalence and risk behaviors among men who have sex with men and inject drugs in San Francisco 
The dual risks of male-to-male sex and drug injection have put men who have sex with men and inject drugs (MSM-IDU) at the forefront of the HIV epidemic, with the highest rates of infection among any risk group in the United States. This study analyzes data collected from 357 MSM-IDU in San Francisco between 1998 and 2002 to examine how risk behaviors differ by HIV serostatus and self-identified sexual orientation and to assess medical and social service utilization among HIV-positive MSM-IDU. Twenty-eight percent of the sample tested HIV antibody positive. There was little difference in risk behaviors between HIV-negative and HIV-positive MSM-IDU. Thirty percent of HIV-positive MSM-IDU reported distributive syringe sharing, compared to 40% of HIV negatives. Among MSM-IDU who reported anal intercourse in past 6 months, 70% of positives and 66% of HIV negatives reported unprotected anal intercourse. HIV status varied greatly by self-identified sexual orientation: 46% among gay, 24% among bisexual, and 14% among heterosexual MSM-IDU. Heterosexual MSM-IDU were more likely than other MSM-IDU to be homeless and to trade sex for money or drugs. Gay MSM-IDU were more likely to have anal intercourse. Bisexual MSM-IDU were as likely as heterosexual MSM-IDU to have sex with women and as likely as gay-identified MSM-IDU to have anal intercourse. Among MSM-IDU who were HIV positive, 15% were currently on antiretroviral therapy and 18% were currently in drug treatment, and 87% reported using a syringe exchange program in the past 6 months. These findings have implications for the development of HIV interventions that target the diverse MSM-IDU population.

11.  The Role of HIV-Related Stigma in Utilization of Skilled Childbirth Services in Rural Kenya: A Prospective Mixed-Methods Study 
PLoS Medicine  2012;9(8):e1001295.
Janet Turan and colleagues examined the role of the perception of women in rural Kenya of HIV-related stigma during pregnancy on their subsequent utilization of maternity services.
Background
Childbirth with a skilled attendant is crucial for preventing maternal mortality and is an important opportunity for prevention of mother-to-child transmission of HIV. The Maternity in Migori and AIDS Stigma Study (MAMAS Study) is a prospective mixed-methods investigation conducted in a high HIV prevalence area in rural Kenya, in which we examined the role of women's perceptions of HIV-related stigma during pregnancy in their subsequent utilization of maternity services.
Methods and Findings
From 2007–2009, 1,777 pregnant women with unknown HIV status completed an interviewer-administered questionnaire assessing their perceptions of HIV-related stigma before being offered HIV testing during their first antenatal care visit. After the visit, a sub-sample of women was selected for follow-up (all women who tested HIV-positive or were not tested for HIV, and a random sample of HIV-negative women, n = 598); 411 (69%) were located and completed another questionnaire postpartum. Additional qualitative in-depth interviews with community health workers, childbearing women, and family members (n = 48) aided our interpretation of the quantitative findings and highlighted ways in which HIV-related stigma may influence birth decisions. Qualitative data revealed that health facility birth is commonly viewed as most appropriate for women with pregnancy complications, such as HIV. Thus, women delivering at health facilities face the risk of being labeled as HIV-positive in the community. Our quantitative data revealed that women with higher perceptions of HIV-related stigma (specifically those who held negative attitudes about persons living with HIV) at baseline were subsequently less likely to deliver in a health facility with a skilled attendant, even after adjusting for other known predictors of health facility delivery (adjusted odds ratio = 0.44, 95% CI 0.22–0.88).
Conclusions
Our findings point to the urgent need for interventions to reduce HIV-related stigma, not only for improving quality of life among persons living with HIV, but also for better health outcomes among all childbearing women and their families.

Editors' Summary
Background
Every year, nearly 350,000 women die from pregnancy- or childbirth-related complications. Almost all these “maternal” deaths occur in developing countries. In sub-Saharan Africa, for example, the maternal mortality ratio (the number of maternal deaths per 100,000 live births) is 500 whereas in industrialized countries it is only 12. Most maternal deaths are caused by hemorrhage (severe bleeding after childbirth), post-delivery infections, obstructed (difficult) labor, and blood pressure disorders during pregnancy. All these conditions can be prevented if women have access to adequate reproductive health services and if trained health care workers are present during delivery. Notably, in sub-Saharan Africa, infection with HIV (the virus that causes AIDS) is an increasingly important contributor to maternal mortality. HIV infection causes maternal mortality directly by increasing the occurrence of pregnancy complications and indirectly by increasing the susceptibility of pregnant women to malaria, tuberculosis, and other “opportunistic” infections—HIV-positive individuals are highly susceptible to other infections because HIV destroys the immune system.
Why Was This Study Done?
Although skilled delivery attendants reduce maternal mortality, there are many barriers to their use in developing countries including cost and the need to travel long distances to health facilities. Fears and experiences of HIV-related stigma and discrimination (prejudice, negative attitudes, abuse, and maltreatment directed at people living with HIV) may also be a barrier to the use of skilled childbirth service. Maternity services are prime locations for HIV testing and for the provision of interventions for the prevention of mother-to-child transmission (PMTCT) of HIV, so pregnant women know that they will have to “deal with” the issue of HIV when visiting these services. In this prospective mixed-methods study, the researchers examine the role of pregnant women's perceptions of HIV-related stigma in their subsequent use of maternity services in Nyanza Province, Kenya, a region where 16% women aged 15–49 are HIV-positive and where only 44.2% of mothers give birth in a health facility. A mixed-methods study combines qualitative data—how people feel about an issue—with quantitative data—numerical data about outcomes.
What Did the Researchers Do and Find?
In the Maternity in Migori and AIDS Stigma (MAMAS) study, pregnant women with unknown HIV status living in rural regions of Nyanza Province answered questions about their perceptions of HIV-related stigma before being offered HIV testing during their first antenatal clinic visit. After delivery, the researchers asked the women who tested HIV positive or were not tested for HIV and a sample of HIV-negative women where they had delivered their baby. They also gathered qualitative information about barriers to maternity and HIV service use by interviewing childbearing women, family members, and community health workers. The qualitative data indicate that labor in a health facility is commonly viewed as being most appropriate for women with pregnancy complications such as HIV infection. Thus, women delivering at health facilities risk being labeled as HIV positive, a label that the community associates with promiscuity. The quantitative data indicate that women with more negative attitudes about HIV-positive people (higher perceptions of HIV-related stigma) at baseline were about half as likely to deliver in a health facility with a skilled attendant as women with more positive attitudes about people living with HIV.
What Do These Findings Mean?
These findings suggest that HIV-related stigma is associated with the low rate of delivery by skilled attendants in rural areas of Nyanza Province and possibly in other rural regions of sub-Saharan Africa. Community mobilization efforts aimed at increasing the use of PMTCT services may be partly responsible for the strong perception that delivery in a health facility is most appropriate for women with HIV and other pregnancy complications and may have inadvertently strengthened the perception that women who give birth in such facilities are likely to be HIV positive. The researchers suggest, therefore, that health messages should stress that delivery in a health facility is recommended for all women, not just HIV-positive women or those with pregnancy complications, and that interventions should be introduced to reduce HIV-related stigma. This combined strategy has the potential to increase the use of maternity services by all women and the use of HIV and PMTCT services, thereby reducing some of the most pressing health problems facing women and their children in sub-Saharan Africa.

12.  Intimate Partner Violence and Social Pressure among Gay Men in Six Countries 
Introduction
Recent research suggests that men who have sex with men (MSM) experience intimate partner violence (IPV) at significantly higher rates than heterosexual men. Few studies, however, have investigated implications of heterosexist social pressures – namely, homophobic discrimination, internalized homophobia, and heterosexism – on risk for IPV among MSM, and no previous studies have examined cross-national variations in the relationship between IPV and social pressure. This paper examines reporting of IPV and associations with social pressure among a sample of internet-recruited MSM in the United States (U.S.), Canada, Australia, the United Kingdom, South Africa, and Brazil.
Methods
We recruited internet-using MSM from 6 countries through selective banner advertisements placed on Facebook. Eligibility criteria were men age over 18 reporting sex with a man in the past year. Of the 2,771 eligible respondents, 2,368 had complete data and were included in the analysis. Three outcomes were examined: reporting recent experience of physical violence, sexual violence, and recent perpetration of physical violence. The analysis focused on associations between reporting of IPV and experiences of homophobic discrimination, internalized homophobia, and heteronormativity.
Results
Reporting of experiencing physical IPV ranged from 5.75% in the U.S. to 11.75% in South Africa, while experiencing sexual violence was less commonly reported and ranged from 2.54% in Australia to 4.52% in the U.S. Perpetration of physical violence ranged from 2.47% in the U.S. to 5.76% in South Africa. Experiences of homophobic discrimination, internalized homophobia, and heteronormativity were found to increase odds of reporting IPV in all countries.
Conclusion
There has been little data on IPV among MSM, particularly MSM living in low- and middle-income countries. Despite the lack of consensus in demographic correlates of violence reporting, heterosexist social pressures were found to significantly increase odds of reporting IPV in all countries. These findings show the universality of violence reporting among MSM across countries, and highlight the unique role of heteronormativity as a risk factor for violence reporting among MSM. The results demonstrate that using internet-based surveys to reach MSM is feasible for certain areas, although modified efforts may be required to reach diverse samples of MSM.

13.  Association of the ANRS-12126 Male Circumcision Project with HIV Levels among Men in a South African Township: Evaluation of Effectiveness using Cross-sectional Surveys 
PLoS Medicine  2013;10(9):e1001509.
Betran Auvert and colleagues report findings from the Bophelo Pele project, a community-based HIV prevention intervention offering free voluntary medical male circumcision (VMMC), that demonstrate an association between VMMC roll-out and a reduction in the incidence and prevalence of HIV in the community.
Please see later in the article for the Editors' Summary
Background
Randomized controlled trials have shown that voluntary medical male circumcision (VMMC) reduces HIV infection by 50% to 60% in sub-Saharan African populations; however, little is known about the population-level effect of adult male circumcision (MC) as an HIV prevention method. We assessed the effectiveness of VMMC roll-out on the levels of HIV in the South African township of Orange Farm where the first randomized controlled trial (RCT) to test the effect of VMMC on HIV acquisition was conducted in 2002–2005.
Methods and Findings
The Bophelo Pele project is a community-based campaign against HIV, which includes the roll-out of free VMMC. A baseline cross-sectional biomedical survey was conducted in 2007–2008 among a random sample of 1,998 men aged 15 to 49 (survey response rate 80.7%). In 2010–2011, we conducted a follow-up random survey among 3,338 men aged 15 to 49 (survey response rate 79.6%) to evaluate the project. Participants were interviewed, blood samples were collected and tested for HIV and recent HIV infection (using the BED HIV incidence assay), and MC status was assessed through a clinical examination. Data were analyzed using multivariate and propensity statistical methods.
Owing to the VMMCs performed in the context of the RCT and the Bophelo Pele project, the prevalence rate of adult MC increased from 0.12 (95% CI 0.10–0.14) to 0.53 (95% CI 0.51–0.55). Without these VMMCs, the HIV prevalence rate in 2010–2011 would have been 19% (95% CI 12%–26%) higher (0.147 instead of 0.123).
When comparing circumcised and uncircumcised men, no association of MC status with sexual behavior was detected. Among circumcised and uncircumcised men, the proportion consistently using condoms with non-spousal partners in the past 12 months was 44.0% (95% CI 41.7%–46.5%) versus 45.4% (95% CI 42.2%–48.6%) with weighted prevalence rate ratio (wPRR) = 0.94 (95% CI 0.85–1.03). The proportion having two or more non-spousal partners was 50.4% (95% CI 47.9%–52.9%) versus 44.2% (95% CI 41.3%–46.9%) with wPRR = 1.03 (95% CI 0.95–1.10).
We found a reduction of BED-estimated HIV incidence rate ranging from 57% (95% CI 29%–76%) to 61% (95% CI 14%–83%) among circumcised men in comparison with uncircumcised men.
Conclusions
Findings suggest that the roll-out of VMMC in Orange Farm is associated with a significant reduction of HIV levels in the community. The main limitation of the study is that it was not randomized and cannot prove a causal association. The roll-out of VMMC among adults in sub-Saharan Africa should be an international priority and needs to be accelerated to effectively combat the spread of HIV.

Editors' Summary
Background
Every year about 2.2 million people (mostly in sub-Saharan Africa) become infected with HIV, the virus that causes AIDS. There is no cure for HIV/AIDS. Consequently, prevention of HIV transmission is extremely important. Because HIV is most often spread through unprotected sex with an infected partner, individuals can reduce their risk of HIV infection by abstaining from sex, by having only one or a few sexual partners, and by always using a male or female condom. The results of three randomized controlled trials conducted in sub-Saharan Africa also suggest that voluntary medical male circumcision (VMMC)—the removal of the foreskin, a loose fold of skin that covers the head of the penis—can reduce the heterosexual acquisition of HIV in men by 50%–60%. In 2007, the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended that VMMC should be offered as part of comprehensive HIV risk reduction programs in settings with generalized HIV epidemics and low levels of male circumcision and prioritized 14 east and southern African countries for VMMC roll-out.
Why Was This Study Done?
To date, about 3 million VMMCs have been performed for HIV prevention but it is not known whether “real world” VMMC roll-out programs will replicate the promising results obtained in the earlier trials. Indeed, there are fears that “risk compensation” (an increase in risky sexual behaviors after VMMC) might lead to increased HIV transmission in regions where VMMC is rolled out. In this study, the researchers use sequential cross-sectional surveys (studies that collect data from a group of people at a single time point) to investigate HIV infection levels in men in Orange Farm, a township in South Africa where one of the randomized controlled trials of VMMC was undertaken. The surveys were conducted before and after implementation of the Bophelo Pele project, a community-based campaign against HIV that was initiated in 2008 and that includes free VMMC.
What Did the Researchers Do and Find?
The researchers asked a random sample of nearly 2,000 men aged 15–49 years about their sexual behavior (for example, how many non-spousal partners they had had over the past year), and their intention to become circumcised if uncircumcised in a baseline survey in 2007–2008. The study participants were also offered HIV counseling and testing (including a test that indicated whether the participant had recently become HIV positive) and were examined to see whether they were already circumcised. A similar follow-up survey was conducted in 2010–2011 in which more than 3,000 men were invited to take part. At baseline, 12% of the men surveyed had been circumcised (a prevalence of circumcision of 12%) whereas in the follow-up survey, the overall prevalence of circumcision and the prevalence of circumcision among 15–29 year-olds (an important target group for VMMC roll-out) were 53% and 58%, respectively. The overall HIV prevalence at follow-up was 12% and the researchers estimated that without the VMMCs performed during the Bophelo Pele project and the preceding randomized control trial the prevalence of HIV among men living in Orange Farm would have been 15% in 2011. Using various cut-off values and corrections for a laboratory-based test to measure recent HIV infections, the researchers reported a reduction in the rate of new HIV infections (incidence rate) ranging from 57% to 61% among circumcised men in comparison with uncircumcised men. Importantly, there was no evidence of an association between circumcision status and risky sexual behavior but circumcision was associated with a reduction in the number of men who had recently become HIV positive.
What Do These Findings Mean?
These findings suggest that VMMC roll out in Orange Farm is associated with a reduction in HIV infection levels in the community and that circumcision is not associated with changes in sexual behavior that might affect HIV infection rates. They also suggest that VMMC roll-out is associated with a rapid uptake of VMMC, especially among young men, in an African community where male circumcision is not a social norm. Because this study is not a randomized controlled trial, it cannot establish cause and effect. Thus, although the observed reduction in HIV prevalence among circumcised men compared to uncircumcised men suggests that circumcision provided protection against HIV acquisition within the study population, the results do not conclusively prove this. The findings of this study nevertheless support the continuation and acceleration of the roll-out of adult VMMC in Africa although further studies are needed to show whether VMMC roll-out is also associated with a reduction in HIV acquisition among women and among uncircumcised men.

14.  Routine HIV Testing in Botswana: A Population-Based Study on Attitudes, Practices, and Human Rights Concerns 
PLoS Medicine  2006;3(7):e261.
Background
The Botswana government recently implemented a policy of routine or “opt-out” HIV testing in response to the high prevalence of HIV infection, estimated at 37% of adults.
Methods and Findings
We conducted a cross-sectional, population-based study of 1,268 adults from five districts in Botswana to assess knowledge of and attitudes toward routine testing, correlates of HIV testing, and barriers and facilitators to testing, 11 months after the introduction of this policy. Most participants (81%) reported being extremely or very much in favor of routine testing. The majority believed that this policy would decrease barriers to testing (89%), HIV-related stigma (60%), and violence toward women (55%), and would increase access to antiretroviral treatment (93%). At the same time, 43% of participants believed that routine testing would lead people to avoid going to the doctor for fear of testing, and 14% believed that this policy could increase gender-based violence related to testing. The prevalence of self-reported HIV testing was 48%. Adjusted correlates of testing included female gender (AOR = 1.5, 95% CI = 1.1–1.9), higher education (AOR = 2.0, 95% CI = 1.5–2.7), more frequent healthcare visits (AOR = 1.9, 95% CI = 1.3–2.7), perceived access to HIV testing (AOR = 1.6, 95% CI = 1.1–2.5), and inconsistent condom use (AOR = 1.6, 95% CI = 1.2–2.1). Individuals with stigmatizing attitudes toward people living with HIV and AIDS were less likely to have been tested for HIV/AIDS (AOR = 0.7, 95% CI = 0.5–0.9) or to have heard of routine testing (AOR = 0.59, 95% CI = 0.45–0.76). While experiences with voluntary and routine testing overall were positive, 68% felt that they could not refuse the HIV test. Key barriers to testing included fear of learning one's status (49%), lack of perceived HIV risk (43%), and fear of having to change sexual practices with a positive HIV test (33%).
Conclusions
Routine testing appears to be widely supported and may reduce barriers to testing in Botswana. As routine testing is adopted elsewhere, measures should be implemented to assure true informed consent and human rights safeguards, including protection from HIV-related discrimination and protection of women against partner violence related to testing.
Editors' Summary
Background.
In 2005, there were 5 million new infections with the human immunodeficiency virus (HIV), and the disease it causes—acquired immunodeficiency syndrome (AIDS)—killed three million people. Despite the increased availability of drugs that can fight HIV (antiretrovirals), the AIDS epidemic continues to grow, particularly in sub-Saharan Africa. To halt it, more needs to be done to prevent the spread of HIV. Education about safe sex can help—HIV is most commonly spread through unprotected sex with an infected partner—but increasing HIV testing is of paramount importance. Unfortunately, the uptake of voluntary counseling and testing in sub-Saharan Africa is worryingly low. Fear of being stigmatized—socially disgraced—and discriminated against, fears about the positive result itself, and worries about access to antiretroviral drugs are all putting people off being tested.
Why Was This Study Done?
In Botswana, one in three adults is infected with HIV. Since 2002, antiretroviral drugs have been freely available but enrollment in the Botswana National Treatment Program during its first two years was slow, in part due to inadequate uptake of voluntary HIV testing. Consequently, in early 2004, the government introduced a policy of routine HIV testing in which all patients are tested for HIV when they visit their doctor unless they opt out. A major aim of this approach to HIV testing, which was formally recommended in June 2004 by UNAIDS and the World Health Organization, is to increase uptake of HIV testing and treatment, and to reduce HIV-related stigma by treating the HIV test like any other routine medical procedure. However, there are fears that the policy could back-fire—people might not visit their doctors, for example, because they are afraid of being tested and think that they will not be able to refuse the test. In this study, the researchers investigated knowledge of and attitudes to routine testing in Botswana to understand better the consequences of a routine testing policy.
What Did the Researchers Do and Find?
The researchers interviewed adults throughout Botswana about their knowledge of and attitudes to routine HIV testing 11 months after introduction of the policy. Only half of the participants had heard of routine testing before being interviewed but nearly all were in favor of routine testing. More than half thought it would reduce HIV-related stigma and the violence toward women that is associated with an HIV-positive status. However, almost half believed that routine testing might prevent people from going to the doctor because of fear of testing and a few thought the policy would increase violence against women. Nearly half of the interviewees had had an HIV test and the researchers found, for example, that women were more likely to have been tested than men and that people with stigmatizing attitudes toward people living with HIV and AIDS were less likely to be tested. Fear of learning one's HIV status, lack of perceived risk, and fear of having to change sexual practices if positive all stopped people taking the test. Finally, although experiences with testing were generally positive, approximately two-thirds of interviewees who had been tested felt that it would have been difficult to refuse the test.
What Do These Findings Mean?
These results show that there is widespread support for routine HIV testing in Botswana, a finding supported by recent increases in treatment uptake. Routine testing, write the researchers, holds significant promise for the prevention and treatment of HIV/AIDS in Botswana and elsewhere. In particular, increasing the number of people tested for HIV may reduce HIV-related stigma, which should further increase testing and hopefully slow the spread of HIV. But the results of this study also highlight some areas of concern. Whenever HIV testing policies are implemented, human rights must be protected by ensuring that patients have all the information necessary to make an informed and free decision about being tested, by providing protection for women against violence related to HIV status, and by ensuring total confidentiality. Careful monitoring of Botswana's program and similar programs will be needed to ensure that these human rights are fully met, conclude the researchers.

15.  Uptake of Home-Based Voluntary HIV Testing in Sub-Saharan Africa: A Systematic Review and Meta-Analysis 
PLoS Medicine  2012;9(12):e1001351.
Kalpana Sabapathy and colleagues conduct a systematic review and meta-analysis to assess the acceptability of home-based voluntary counseling and testing for HIV in sub-Saharan Africa with some encouraging results.
Introduction
Improving access to HIV testing is a key priority in scaling up HIV treatment and prevention services. Home-based voluntary counselling and testing (HBT) as an approach to delivering wide-scale HIV testing is explored here.
Methods and Findings
We conducted a systematic review and random-effects meta-analysis of studies published between 1 January 2000 and 24 September 2012 that reported on uptake of HBT in sub-Saharan Africa, to assess the proportion of individuals accepting HBT and receiving their test result.
Our initial search yielded 1,199 articles; 114 were reviewed as full-text articles, and 19 publications involving 21 studies (n = 524,867 individuals offered HBT) were included for final review and meta-analysis. The studies came from five countries: Uganda, Malawi, Kenya, South Africa, and Zambia.
The proportion of people who accepted HBT (n = 474,377) ranged from 58.1% to 99.8%, with a pooled proportion of 83.3% (95% CI: 80.4%–86.1%). Heterogeneity was high (τ2 = 0.11). Sixteen studies reported on the number of people who received the result of HBT (n = 432,835). The proportion of individuals receiving their results out of all those offered testing ranged from 24.9% to 99.7%, with a pooled proportion of 76.7% (95% CI: 73.4%–80.0%) (τ2 = 0.12). HIV prevalence ranged from 2.9% to 36.5%. New diagnosis of HIV following HBT ranged from 40% to 79% of those testing positive. Forty-eight percent of the individuals offered testing were men, and they were just as likely to accept HBT as women (pooled odds ratio = 0.84; 95% CI: 0.56–1.26) (τ2 = 0.33). The proportion of individuals previously tested for HIV among those offered a test ranged from 5% to 66%. Studies in which <30% of individuals had been previously tested, local HIV prevalence was <10%, incentives were provided, or HBT was offered to household members of HIV-positive individuals showed higher uptake of testing. No evidence was reported of negative consequences of HBT.
Conclusions
HBT could substantially increase awareness of HIV status in previously undiagnosed individuals in sub-Saharan Africa, with over three-quarters of the studies in this review reporting >70% uptake. It could be a valuable tool for treatment and prevention efforts.

Editors' Summary
Background
Knowledge of HIV status is crucial for both the prevention and treatment of HIV. However, according to the Joint United Nations Programme on HIV/AIDS (the UN agency responsible for HIV/AIDS), in low-and-middle-income countries only ten percent of those who need voluntary counseling and testing, because they may have been exposed to HIV infection, have access to this service. Even in health care settings in which voluntary counseling and HIV testing is routinely offered, such as to pregnant women, the number of people who use these services is low. This situation is partly because of the stigma and discrimination associated with HIV, which makes people reluctant to volunteer to come forward to be tested for HIV. To help overcome this problem, one important strategy in encouraging people to be tested for HIV is to offer them the opportunity to be counseled and tested at home—home-based voluntary counseling and testing (HBT). Using the HBT approach, people are visited in their home by health workers regardless of their perceived risk of HIV. HBT has obvious advantages and upholds the “3 Cs” principles of HIV testing: that testing is confidential, accompanied by counseling, and conducted only with informed consent.
Why Was This Study Done?
The HBT approach has received widespread international support, and the World Health Organization has recently published guidance to service providers and policy makers about the delivery of HBT. However, the acceptability of HBT, that is, whether those offered HBT actually take up the offer and are tested, remains unknown, especially in sub-Saharan Africa, the world region with the highest prevalence of HIV. So, in this study, the researchers systematically compiled all of the available studies on this topic from sub-Saharan Africa to determine the acceptability of HBT and also to and identify any factors associated with the uptake of HBT.
What Did the Researchers Do and Find?
The researchers searched several databases to identify suitable peer-reviewed studies from Africa published between January 2000 and September 2012. The researchers included studies that described any intervention to provide HIV testing at home and also reported the proportions of participants accepting HIV testing out of all individuals offered a home-based HIV test. Because different types of studies were included (such as randomized controlled trials, observational cohort studies, and cross-sectional surveys), the researchers tested the quality of included studies. Then they pooled all of the studies together to calculate the overall proportion of people who accepted HIV testing at home and the proportion who received their result.
Using these methods, the researchers included 21 studies from five African countries: Kenya, Malawi, South Africa, Uganda, and Zambia, comprising a total of 524,867 people. Overall, the proportion of people who accepted HBT ranged from 58.1% to 99.7%, with a pooled proportion of 83.3% accepting HBT (474,377 people). In the eight studies that separated data by gender, men were as likely as women to accept testing (78.5% versus 81.5%). Over three-quarters of everyone who accepted HBT received their result (77% in 16 studies reporting on this), and, importantly, the proportion of people with previously undiagnosed HIV was high (40%–79% of those diagnosed HIV-positive), emphasizing the value of HBT. The researchers also found that providing incentives, local HIV prevalence being less than 10%, and targeting HBT to household members of HIV-positive individuals may be factors associated with increased uptake of HBT, but further research is needed to verify the results of this subgroup analysis.
What Do These Findings Mean?
These findings suggest that voluntary counseling and testing for HIV at home is highly acceptable in five countries in sub-Saharan Africa, with the majority of those tested receiving their test result, highlighting the importance of this approach in the diagnosis of HIV. Therefore, by increasing uptake of testing, HBT may provide an effective tool for governments and health service providers to increase access to HIV treatment and prevention. However, testing is just the first step in the management of HIV, and this study does not address the follow-up of those who tested positive using the home-based approach, such as access to treatment, as well as repeated HBT for ongoing knowledge of HIV status. The option of self-testing was examined in only one of the studies included in this review, but the researchers identify that self-testing at home with the support HBT staff is an important area of future research. Overall, HBT has the potential to substantially increase awareness of HIV status in previously undiagnosed men and women in sub-Saharan Africa.

16.  Participation of HIV prevention programs among men who have sex with men in two cities of China—a mixed method study 
BMC Public Health  2012;12:847.
Background
Although various HIV prevention programs targeting men who have sex with men (MSM) are operating in China, whether and how these programs are being utilized is unclear. This study explores participation of HIV prevention programs and influencing factors among MSM in two cities in China.
Methods
This is a mixed-method study conducted in Beijing and Chongqing. A qualitative study consisting of in-depth interviews with 54 MSM, 11 key informants, and 8 focus group discussions, a cross-sectional survey using respondent-driven sampling among 998 MSM were conducted in 2009 and 2010 respectively to elicit information on MSM’s perception and utilization of HIV prevention programs. Qualitative findings were integrated with quantitative multivariate factors to explain the quantitative findings.
Results
Fifty-six percent of MSM in Chongqing and 75.1% in Beijing ever participated in at least one type of HIV prevention program (P=0.001). Factors related to participation in HIV prevention programs included age, ethnicity, income, HIV risk perception, living with boyfriend, living in urban area, size of MSM social network, having talked about HIV status with partners, and knowing someone who is HIV positive. Reasons why MSM did not participate in HIV prevention programs included logistical concerns like limited time for participation and distance to services; program content and delivery issues such as perceived low quality services and distrust of providers; and, cultural issues like HIV-related stigma and low risk perception.
Conclusions
The study shows that there is much room for improvement in reaching MSM in China. HIV prevention programs targeting MSM in China may need to be more comprehensive and incorporate the cultural, logistic and HIV-related needs of the population in order to effectively reach and affect this population’s risk for HIV.

17.  Bacterial Vaginosis Associated with Increased Risk of Female-to-Male HIV-1 Transmission: A Prospective Cohort Analysis among African Couples 
PLoS Medicine  2012;9(6):e1001251.
In a prospective study, Craig Cohen and colleagues investigate the association between bacterial vaginosis and the risk of female-to-male HIV-1 transmission.
Background
Bacterial vaginosis (BV), a disruption of the normal vaginal flora, has been associated with a 60% increased risk of HIV-1 acquisition in women and higher concentration of HIV-1 RNA in the genital tract of HIV-1–infected women. However, whether BV, which is present in up to half of African HIV-1–infected women, is associated with an increase in HIV-1 transmission to male partners has not been assessed in previous studies.
Methods and Findings
We assessed the association between BV on female-to-male HIV-1 transmission risk in a prospective study of 2,236 HIV-1–seropositive women and their HIV-1 uninfected male partners from seven African countries from a randomized placebo-controlled trial that enrolled heterosexual African adults who were seropositive for both HIV-1 and herpes simplex virus (HSV)-2, and their HIV-1–seronegative partners. Participants were followed for up to 24 months; every three months, vaginal swabs were obtained from female partners for Gram stain and male partners were tested for HIV-1. BV and normal vaginal flora were defined as a Nugent score of 7–10 and 0–3, respectively. To reduce misclassification, HIV-1 sequence analysis of viruses from seroconverters and their partners was performed to determine linkage of HIV-1 transmissions. Overall, 50 incident HIV-1 infections occurred in men in which the HIV-1–infected female partner had an evaluable vaginal Gram stain. HIV-1 incidence in men whose HIV-1–infected female partners had BV was 2.91 versus 0.76 per 100 person-years in men whose female partners had normal vaginal flora (hazard ratio 3.62, 95% CI 1.74–7.52). After controlling for sociodemographic factors, sexual behavior, male circumcision, sexually transmitted infections, pregnancy, and plasma HIV-1 RNA levels in female partners, BV was associated with a greater than 3-fold increased risk of female-to-male HIV-1 transmission (adjusted hazard ratio 3.17, 95% CI 1.37–7.33).
Conclusions
This study identified an association between BV and increased risk of HIV-1 transmission to male partners. Several limitations may affect the generalizability of our results including: all participants underwent couples HIV counseling and testing and enrolled in an HIV-1 prevention trial, and index participants had a baseline CD4 count ≥250 cells/mm3 and were HSV-2 seropositive. Given the high prevalence of BV and the association of BV with increased risk of both female HIV-1 acquisition and transmission found in our study, if this association proves to be causal, BV could be responsible for a substantial proportion of new HIV-1 infections in Africa. Normalization of vaginal flora in HIV-1–infected women could mitigate female-to-male HIV-1 transmission.

Editors' Summary
Background
Since the first reported case of AIDS in 1981, the number of people infected with HIV, the virus that causes AIDS, has risen steadily. By the end of 2010, 34 million people were living with HIV/AIDS. At the beginning of the epidemic more men than women were infected with HIV. Now, however, 50% of all adults infected with HIV are women and in sub-Saharan Africa, where two-thirds of HIV-positive people live, women account for 59% of people living with HIV. Moreover, among 15–24 year-olds, women are eight times more likely than men to be HIV-positive. This pattern of infection has developed because most people in sub-Saharan Africa contract HIV through unprotected heterosexual sex. The risk of HIV transmission for both men and women in Africa and elsewhere can be reduced by abstaining from sex, by only having one or a few partners, by always using condoms, and by male circumcision. In addition, several studies suggest that antiretroviral therapy (ART) greatly reduces HIV transmission.
Why Was This Study Done?
Unfortunately, in sub-Saharan Africa, only about a fifth of HIV-positive people are currently receiving ART, which means that there is an urgent need to find other effective ways to reduce HIV transmission in this region. In this prospective cohort study (a type of study that follows a group of people for some time to see which personal characteristics are associated with disease development), the researchers investigate whether bacterial vaginosis—a condition in which harmful bacteria disrupt the normal vaginal flora—increases the risk of female-to-male HIV transmission among African couples. Bacterial vaginosis, which is extremely common in sub-Saharan Africa, has been associated with an increased risk of HIV acquisition in women and induces viral replication and shedding in the vagina in HIV-positive women, which may mean that HIV-positive women with bacterial vaginosis are more likely to transmit HIV to their male partners than women without this condition. If this is the case, then interventions that reduce the incidence of bacterial vaginosis might be valuable HIV prevention strategies.
What Did the Researchers Do and Find?
The researchers analyzed data collected from 2,236 heterosexual African couples enrolled in a clinical trial (the Partners in Prevention HSV/HIV Transmission Study) whose primary aim was to investigate whether suppression of herpes simplex virus infection could prevent HIV transmission. In all the couples, the woman was HIV-positive and the man was initially HIV-negative. The female partners were examined every three months for the presence of bacterial vaginosis and the male partners were tested regularly for HIV infection. The researchers also determined whether the men who became HIV-positive were infected with the same HIV strain as their partner to check that their infection had been acquired from this partner. The HIV incidence in men whose partners had bacterial vaginosis was 2.9 per 100 person-years (that is, 2.9 out of every 100 men became HIV-positive per year) whereas the HIV incidence in men whose partners had a normal vaginal flora was 0.76 per 100 person-years. After controlling for factors that might affect the risk of HIV transmission such as male circumcision and viral levels in female partner's blood, the researchers estimated that bacterial vaginosis was associated with a 3.17-fold increased risk of female-to-male HIV transmission in their study population.
What Do These Findings Mean?
These findings suggest that HIV-positive African women with bacterial vaginosis are more than three times as likely to transmit HIV to their male partners as those with a normal vaginal flora. It is possible that some unknown characteristic of the men in this study might have increased both their own risk of HIV infection and their partner's risk of bacterial vaginosis. Nevertheless, because bacterial vaginosis is so common in Africa (half of the women in this study had bacterial vaginosis at least once during follow-up) and because this condition is associated with both female HIV acquisition and transmission, these findings suggest that bacterial vaginosis could be responsible for a substantial proportion of new HIV infections in Africa. Normalization of vaginal flora in HIV-infected women by frequent presumptive treatment with antimicrobials (treatment with a curative dose of antibiotics without testing for bacterial vaginosis) or possibly by treatment with probiotics (live “good” bacteria) might, therefore, reduce female-to-male HIV transmission in sub-Saharan Africa.

Background
Conventional epidemiological surveillance of infectious diseases is focused on characterization of incident infections and estimation of the number of prevalent infections. Advances in methods for the analysis of the population-level genetic variation of viruses can potentially provide information about donors, not just recipients, of infection. Genetic sequences from many viruses are increasingly abundant, especially HIV, which is routinely sequenced for surveillance of drug resistance mutations. We conducted a phylodynamic analysis of HIV genetic sequence data and surveillance data from a US population of men who have sex with men (MSM) and estimated incidence and transmission rates by stage of infection.
Methods and Findings
We analyzed 662 HIV-1 subtype B sequences collected between October 14, 2004, and February 24, 2012, from MSM in the Detroit metropolitan area, Michigan. These sequences were cross-referenced with a database of 30,200 patients diagnosed with HIV infection in the state of Michigan, which includes clinical information that is informative about the recency of infection at the time of diagnosis. These data were analyzed using recently developed population genetic methods that have enabled the estimation of transmission rates from the population-level genetic diversity of the virus. We found that genetic data are highly informative about HIV donors in ways that standard surveillance data are not. Genetic data are especially informative about the stage of infection of donors at the point of transmission. We estimate that 44.7% (95% CI, 42.2%–46.4%) of transmissions occur during the first year of infection.
Conclusions
In this study, almost half of transmissions occurred within the first year of HIV infection in MSM. Our conclusions may be sensitive to un-modeled intra-host evolutionary dynamics, un-modeled sexual risk behavior, and uncertainty in the stage of infected hosts at the time of sampling. The intensity of transmission during early infection may have significance for public health interventions based on early treatment of newly diagnosed individuals.

Editors' Summary
Background
Since the first recorded case of AIDS in 1981, the number of people infected with HIV, the virus that causes AIDS, has risen steadily. About 34 million people are currently HIV-positive, and about 2.5 million people become newly infected with HIV every year. Because HIV is usually transmitted through unprotected sex with an infected partner, individuals can reduce their risk of infection by abstaining from sex, by having only one or a few partners, and by always using condoms. Most people do not become ill immediately after infection with HIV, although some develop a short flu-like illness. The next stage of HIV infection, which may last more than ten years, also has no major symptoms, but during this stage, HIV slowly destroys immune system cells. Eventually, the immune system can no longer fight off infections by other disease-causing organisms, and HIV-positive people then develop one or more life-threatening AIDS-defining conditions, including unusual infections and specific types of cancer. HIV infection can be controlled, but not cured, by taking a daily cocktail of antiretroviral drugs.
Why Was This Study Done?
The design of effective programs to prevent the spread of HIV/AIDS depends on knowing how HIV transmissibility varies over the course of HIV infection. Consider, for example, a prevention strategy that focuses on increasing treatment rates: antiretroviral drugs, in addition to reducing illness and death among HIV-positive people, reduce HIV transmission from HIV-positive individuals. “Treatment as prevention” can only block transmissions that occur after diagnosis and entry into care. However, the transmissibility of HIV per sexual contact depends on a person's viral load, which peaks during early HIV infection, when people are often unaware of their HIV status and may still be following the high-risk patterns of sexual behavior that caused their own infection. Epidemiological surveillance data (information on HIV infections within populations) can be used to estimate how many new HIV infections occur within a population annually (HIV incidence) and the proportion of the population that is HIV-positive (HIV prevalence), but cannot be used to estimate the timing of transmission events. In this study, the researchers use “phylodynamic analysis” to estimate HIV incidence and prevalence and the timing of HIV transmission during infection. HIV, like many other viruses, rapidly accumulates genetic changes. The timing of transmission influences the pattern of these changes. Viral phylodynamic analysis—the quantitative study of how epidemiological, immunological, and evolutionary processes shape viral phylogenies (evolutionary trees)—can therefore provide estimates of transmission dynamics.
What Did the Researchers Do and Find?
The researchers obtained HIV sequence data (collected for routine surveillance of antiretroviral resistance mutations) and epidemiological surveillance data (including information on the stage of infection at diagnosis) for 662 HIV-positive men who have sex with men living in the Detroit metropolitan area of Michigan. They constructed a phylogenetic tree from the sequences using a “relaxed clock” approach and then fitted an epidemiological model (a mathematical model that represents the progress of individual patients through various stages of HIV infection) to the sequence data. Their approach, which integrates surveillance data and genetic data, yielded estimates of HIV incidence and prevalence among the study population similar to those obtained from surveillance data alone. However, it also provided information about HIV transmission that could not be obtained from surveillance data alone. In particular, it allowed the researchers to estimate that, in the current HIV epidemic among men who have sex with men in Detroit, 44.7% of HIV transmissions occur during the first year of infection.
What Do These Findings Mean?
The robustness of these findings depends on the validity of the assumptions included in the researchers' population genetic model and on the accuracy of the data fed into the model, and may not be generalizable to other cities or to other risk groups. Nevertheless, the findings of this analysis, which can be repeated in any setting where HIV sequence data for individual patients can be linked to patient-specific clinical and behavioral information, have important implications for HIV control strategies based on the early treatment of newly diagnosed individuals. Because relatively few infected individuals are diagnosed during early HIV infection, when the HIV transmission rate is high, it is unlikely, suggest the researchers, that the “treatment as prevention” strategy will effectively control the spread of HIV unless there are very high rates of HIV testing and treatment.

19.  Bridging Sexual Boundaries: Men Who Have Sex with Men and Women in a Street-Based Sample in Los Angeles 
The purpose of the study was to determine the potential contribution of bisexual men to the spread of HIV in Los Angeles. We compare the characteristics and behaviors of men who have sex with men and women (MSMW) to men who have sex with only women (MSW) and men who have sex with only men (MSM) in Los Angeles. Men (N = 1,125) who participated in one of the two waves of data collection from 2005 to 2007 at the Los Angeles site for NIDA’s Sexual Acquisition and Transmission of HIV—Cooperative Agreement Program were recruited using Respondent Driven Sampling. Participants completed Audio Computer Assisted Self Interviews and received oral HIV rapid testing with confirmatory blood test by Western Blot and provided urine specimens for detection of recent powder cocaine, crack cocaine, methamphetamine, or heroin use. MSM, MSW, or MSMW were defined by the gender of whom they reported sex with in the past 6 months. Chi-square tests and ANOVAs were used to test independence between these groups and demographic characteristics, substance use, and sexual behaviors. We fit generalized linear random intercept models to predict sexual risk behaviors at the partner level. Men were mostly of low income, unemployed, and minority, with many being homeless; 66% had been to jail or prison, 29% had ever injected drugs, and 25% had used methamphetamine in the past 30 days. The sample had high HIV prevalence: 12% of MSMW, 65% of MSM, and 4% of MSW. MSMW were behaviorally between MSW and MSM, except that more MSMW practiced sex for trade (both receiving and giving), and more MSMW had partners who are drug users than MSW. Generalized linear random intercept models included a partner-level predictor with four partner groups: MSM, MSMW-male partners, MSMW-female partners, and MSW. The following were significantly associated with unprotected anal intercourse (UAI): MSW (AOR 0.15, 95% CI 0.08, 0.27), MSMW-female partners (AOR 0.4, 95% CI 0.27, 0.61), HIV-positive partners (AOR 2.03, 95% CI 1.31, 3.13), and being homeless (AOR 1.37, 95% CI 1.01, 1.86). The factors associated with giving money or drugs for sex were MSMW-female partners (AOR 1.70, 95% CI 1.09, 2.65), unknown HIV status partners (AOR 1.72, 95% CI 1.29, 2.30), being older (AOR 1.02, 95% CI 1.00, 1.04), history of incarceration (AOR 1.64, 95% CI 1.17, 2.29), and being homeless (AOR 1.73, 95% CI 1.27, 2.36). The following were associated with receiving money or drugs for sex: MSW (AOR 0.53, 95% CI 0.32, 0.89), African American (AOR 2.42, 95% CI 1.56, 3.76), Hispanic (AOR 1.85, 95% CI 1.12, 3.05), history of incarceration (AOR 1.44, 95% CI 1.04, 2.01), history of injecting drugs (AOR 1.57, 95% CI 1.13, 2.19), and had been recently homeless (AOR 2.14, 95% CI 1.57, 2.94). While overall HIV-positive MSM had more UAI with partners of any HIV status than MSMW with either partner gender, among HIV-positive MSMW, more had UAI with HIV-negative and HIV status unknown female partners than male partners. Findings highlight the interconnectedness of sexual and drug networks in this sample of men—as most have partners who use drugs and they use drugs themselves. We find a concentration of risk that occurs particularly among impoverished minorities—where many men use drugs, trade sex, and have sex with either gender. Findings also suggest an embedded core group of drug-using MSMW who may not so much contribute to spreading the HIV epidemic to the general population, but driven by their pressing need for drugs and money, concentrate the epidemic among men and women like themselves who have few resources.

20.  A Model for the Roll-Out of Comprehensive Adult Male Circumcision Services in African Low-Income Settings of High HIV Incidence: The ANRS 12126 Bophelo Pele Project 
PLoS Medicine  2010;7(7):e1000309.
Bertrand Auvert and colleagues describe the large-scale roll-out of adult male circumcision through a program in South Africa.
Background
World Health Organization (WHO)/Joint United Nations Programme on AIDS (UNAIDS) has recommended adult male circumcision (AMC) for the prevention of heterosexually acquired HIV infection in men from communities where HIV is hyperendemic and AMC prevalence is low. The objective of this study was to investigate the feasibility of the roll-out of medicalized AMC according to UNAIDS/WHO operational guidelines in a targeted African setting.
Methods and Findings
The ANRS 12126 “Bophelo Pele” project was implemented in 2008 in the township of Orange Farm (South Africa). It became functional in 5 mo once local and ethical authorizations were obtained. Project activities involved community mobilization and outreach, as well as communication approaches aimed at both men and women incorporating broader HIV prevention strategies and promoting sexual health. Free medicalized AMC was offered to male residents aged 15 y and over at the project's main center, which had been designed for low-income settings. Through the establishment of an innovative surgical organization, up to 150 AMCs under local anesthesia, with sterilized circumcision disposable kits and electrocautery, could be performed per day by three task-sharing teams of one medical circumciser and five nurses. Community support for the project was high. As of November 2009, 14,011 men had been circumcised, averaging 740 per month in the past 12 mo, and 27.5% of project participants agreed to be tested for HIV. The rate of adverse events, none of which resulted in permanent damage or death, was 1.8%. Most of the men surveyed (92%) rated the services provided positively. An estimated 39.1% of adult uncircumcised male residents have undergone surgery and uptake is steadily increasing.
Conclusion
This study demonstrates that a quality AMC roll-out adapted to African low-income settings is feasible and can be implemented quickly and safely according to international guidelines. The project can be a model for the scale-up of comprehensive AMC services, which could be tailored for other rural and urban communities of high HIV prevalence and low AMC rates in Eastern and Southern Africa.

Editors' Summary
Background
Acquired immunodeficiency syndrome (AIDS) has killed about 25 million people since 1981, and more than 30 million people (22 million in sub-Saharan Africa alone) are now infected with the human immunodeficiency virus (HIV), which causes AIDS. There is no cure for HIV/AIDS. Consequently, prevention of HIV infection is extremely important. Because HIV is most often spread through unprotected sex with an infected partner, individuals can reduce their risk of HIV infection by abstaining from sex, by having one or a few partners, and by always using a male or female condom. In addition, three trials in sub-Saharan Africa recently reported that medicalized adult male circumcision (AMC)—the surgical removal of the foreskin, a loose fold of skin that covers the head of the penis—can reduce HIV transmission rates in men by more than a half. Thus, AMC delivered as a catch-up campaign—in the long-term, circumcision of male infants is likely to be a more sustainable strategy—has the potential to reduce the prevalence of HIV (the proportion of the population infected with HIV) in sub-Saharan Africa.
Why Was This Study Done?
The World Health Organization (WHO) and the Joint United Nations Programme on AIDS (UNAIDS) now recommend that AMC programs should be rolled-out wherever there is a generalized HIV epidemic and few men are circumcised. Accordingly, these organizations have defined a minimum package of AMC services and have issued guidelines and tools designed to engage communities in the roll-out and to ensure that appropriate AMC counseling and surgical facilities are available. But is rapid AMC roll-out feasible in real-life settings? Here, the researchers try to find out by studying the “Bophelo Pele” (Health First) project. This project, which follows the WHO/UNAIDS guidelines for AMC, aims to offer free, safe AMC services to all men aged 15 years or more living in the Orange Farm township in South Africa as part of a community-based intervention against HIV. Orange Farm is in a low-income region of South Africa where HIV prevalence is 15.2% and AMC prevalence is about 25%.
What Did the Researchers Do and Find?
Before the Bophelo Pele project started in January 2008, the researchers consulted the community about the implementation of AMC, helped to create a community advisory board, organized community workshops to discuss the project, and surveyed people's knowledge about AMC and willingness to undergo AMC. These activities indicated a high level of community support for the project and a high level of willingness among men to undergo AMC. Once the project started, the researchers used multiple communication channels to tell the Orange Farm residents about AMC and broader HIV prevention strategies and provided eligible men with counseling about AMC and with voluntary HIV counseling and testing during the recruitment process. Three days after recruitment, eligible men were circumcised free-of-charge at the project's main center, where three teams of one medical circumciser and five nurses were able to complete up to 150 AMCs per day. By November 2009, 14,011 men had been circumcised (more than a third of the eligible men in the township), and AMC uptake was still increasing steadily. Nearly all the men circumcised over one 2-month period rated the AMC services positively in a survey and adverse effects (all mild) occurred after fewer than 1 in 50 circumcisions.
What Do These Findings Mean?
These findings suggest that the rapid roll-out of high-quality, free AMC as an intervention against HIV has been successful in the Orange Farm township. However, other findings highlight some of the challenges that face AMC roll-out. For example, only a quarter of the participants agreed to voluntary HIV counseling and testing, which is worrying because newly circumcised HIV-positive men have an increased risk of transmitting HIV if they resume sexual activity too soon after the operation. Similarly, only two-thirds of the participants returned for a check-up after circumcision; this proportion needs to be increased to ensure the safety and efficacy of AMC programs. Nevertheless, these findings and those from similar intervention programs in Kenya and Uganda indicate that AMC scale-up should be feasible, at least in the short term, as an HIV prevention strategy in low-income communities where there is a high HIV prevalence and a low AMC rate.

21.  Can current national surveillance systems in England and Wales monitor sexual transmission of hepatitis C among HIV-infected men who have sex with men? 
BMC Public Health  2007;7:7.
Background
Recent reports suggest an increase in sexually-transmitted hepatitis C infection among HIV-infected men who have sex with men (MSM) in European cities. We investigated whether current national surveillance systems in England and Wales (E&W) are able to monitor sexual transmission of hepatitis C infection among HIV-infected MSM.
Methods
Routine laboratory reports of hepatitis C diagnoses and data from sentinel hepatitis C testing surveillance were matched to HIV diagnosis reports to determine: (i) the number of MSM diagnosed with HIV and hepatitis C (1996–2003); (ii) the number of HIV-diagnosed MSM tested for hepatitis C and found to be positive at sentinel sites (2003).
Results
(i) Between 1996–2003, 38,027 hepatitis C diagnoses were reported; 25,938 (68%) were eligible for matching with HIV diagnoses. Thirty-one men (four in London) had both a HIV and hepatitis C diagnosis where the only risk was sex with another man. Numbers of "co-diagnosed" MSM increased from 0 in 1996 to 14 in 2003. The majority of MSM (22/31) tested hepatitis C positive after HIV diagnosis. (ii) Of 78,058 test results from sentinel hepatitis C testing sites in 2003, 67,712 (87%) were eligible for matching with HIV diagnoses. We identified 242 HIV-diagnosed MSM who did not inject drugs who tested for hepatitis C in 2003; 11 (4.5%) tested hepatitis C positive (95%CI: 2.3%–8.0%). Applying this percentage to all MSM seen for HIV-related care in E&W in 2003, an estimated 680 MSM living with diagnosed HIV would have tested positive for sexually-transmitted hepatitis C (95%CI: 346–1208).
Conclusion
Matching routine laboratory reports of hepatitis C diagnoses with HIV diagnoses only identified 31 HIV infected MSM with sexually-transmitted hepatitis C infection. Clinical studies suggest that this is an underestimate. On the other hand, matching sentinel surveillance reports with HIV diagnoses revealed that in E&W in 2003 nearly 5% of HIV-diagnosed MSM tested hepatitis C positive where the only risk was sex with another man. Reports of sexually-transmitted hepatitis C infection were not confined to London. Enhanced surveillance is needed to monitor sexually-transmitted hepatitis C among HIV-infected MSM in E&W.

22.  HIV, syphilis and sexual risk behaviours among men who have sex with men in Agadir and Marrakesh, Morocco 
Sexually Transmitted Infections  2013;89(Suppl 3):iii45-iii48.
Objective
To collect baseline measurements of HIV and syphilis prevalence and sexual risk behaviours among men who have sex with men (MSM) in Agadir and Marrakech, Morocco, and provide strategic information to improve outreach programmes.
Methods and Design
Respondent-driven sampling was used to recruit men who reported having anal sex with another man in the last 6 months, aged 18 years and older and living in either Agadir or Marrakech for the past 6 months, regardless of nationality. Data were analysed with the multiplicity estimator using respondent-driven sampling analysis tool V.6.0.
Results
323 MSM in Agadir and 346 in Marrakech were recruited into the survey. Most MSM in both cities reported being < 25 years, being unemployed, bisexual and in a couple with both a man and a woman. Most reported selling sex and having sex with women. HIV prevalence was 5.6% in Agadir and 2.8% in Marrakesh; syphilis was 7.0% in Agadir and 10.8% in Marrakesh. Among MSM who tested positive for HIV, 31.6% in Agadir and 56.4% in Marrakesh were co-infected with syphilis.
Conclusions
HIV and syphilis findings coupled with high risk activities indicate the need for expanding programmes targeting MSM throughout Morocco. Selling sex and sex with women may be a strategy to cope with extreme stigma towards MSM. Criminalisation and discrimination of MSM in Morocco underscores the urgent need for long-term and sustainable risk reduction through legal reforms and promotion and protection of human rights.

23.  ANRS–COM'TEST: description of a community-based HIV testing intervention in non-medical settings for men who have sex with men 
BMJ Open  2012;2(2):e000693.
Objective
To describe a community-based HIV testing programme.
Design and setting
An intervention of HIV voluntary testing conducted in non-medical settings in four French cities.
Participants
Men who have sex with men (MSM).
Intervention
Counselling and rapid HIV testing staffed by trained personnel from an HIV/AIDS community-based organisation.
Primary and secondary outcome measures
The population that has taken hold of the intervention and the satisfaction of participants. Data were collected on demographics, HIV testing history, sexual practices and satisfaction with the testing programme.
Results
532 MSM were tested between February 2009 and June 2010, of whom 49 (9%) were tested two or more times. 468 MSM (88%) had casual male partners in the previous 6 months, and 152 (35%) reported having unprotected anal intercourse with risky casual partners (HIV infected or HIV serostatus unknown). 159 men (30%) had not been tested in the previous 2 years, and 50 (31%) of whom had unprotected anal intercourse with risky casual partners. Among the 15 patients who tested positive (2.8%), 12 (80%) received confirmation and were linked to care (median CD4 cell count =550/mm3). Satisfaction was high: 92% reported being ‘very satisfied’ with their experience. Steps of counselling and testing procedure were respected by testers and difficulties in handling tests were rare.
Conclusions
This community-based HIV testing programme reached high-risk MSM, of whom a substantial proportion had not been tested lately. This novel service supplements pre-existing HIV testing services and increases access to HIV testing in high-risk groups.
Article summary
Article focus
How extend testing facilities to reach and test for HIV more MSM and diagnose HIV-infected MSM earlier?
The presence of peers and non-clinical staff members who address sexuality more openly and avoid medical jargon during counselling sessions could offset cultural barriers and reduce fears of HIV and associated stigma.
The article describes an experimental programme of community-based HIV testing: the population reached, the quality of the programme and the satisfaction of participants.
Key messages
This community-based HIV testing and counselling programme reaches MSM with high-risk sexual behaviour, a substantial proportion of whom has not tested for HIV recently.
Community testers are able to perform rapid HIV test into a comprehensive prevention approach in line with participant's life.
2.8% of participants tested positive. Infection was confirmed in all cases, 80% were linked to care. Cases were diagnosed at early stages of disease.
Strengths and limitations of this study
This HIV testing and counselling programme is exclusively based on MSM community, and continuing the prevention counselling with the awareness of the HIV serostatus includes testing into a comprehensive prevention approach.
Community-based HIV testing programmes may be attractive and efficient in large urban areas (like Paris), but perhaps less so in smaller cities, where an outreach approach may work better.
The number of HIV diagnoses was small; the prevalence and median CD4 count among the few HIV-infected participants should therefore be interpreted with caution.

24.  Increases in sexually transmitted infections and sexual risk behaviour without a concurrent increase in HIV incidence among men who have sex with men in San Francisco: a suggestion of HIV serosorting? 
Sexually Transmitted Infections  2006;82(6):461-466.
Background
Sexually transmitted infections (STI) and unprotected anal intercourse (UAI) have been increasing among men who have sex with men (MSM) in San Francisco. However, HIV incidence has stabilised.
Objectives
To describe recent trends in sexual risk behaviour, STI, and HIV incidence among MSM in San Francisco and to assess whether increases in HIV serosorting (that is, selective unprotected sex with partners of the same HIV status) may contribute to preventing further expansion of the epidemic.
Methods
The study applies an ecological approach and follows the principles of second generation HIV surveillance. Temporal trends in biological and behavioural measures among MSM were assessed using multiple pre‐existing data sources: STI case reporting, prevention outreach programmatic data, and voluntary HIV counselling and testing data.
Results
Reported STI cases among MSM rose from 1998 through 2004, although the rate of increase slowed between 2002 and 2004. Rectal gonorrhoea cases increased from 157 to 389 while early syphilis increased from nine to 492. UAI increased overall from 1998 to 2004 (p<0.001) in community based surveys; however, UAI with partners of unknown HIV serostatus decreased overall (p<0.001) among HIV negative MSM, and among HIV positive MSM it declined from 30.7% in 2001 to a low of 21.0% in 2004 (p<0.001). Any UAI, receptive UAI, and insertive UAI with a known HIV positive partner decreased overall from 1998 to 2004 (p<0.001) among MSM seeking anonymous HIV testing and at the STI clinic testing programme. HIV incidence using the serological testing algorithm for recent HIV seroconversion (STARHS) peaked in 1999 at 4.1% at the anonymous testing sites and 4.8% at the STI clinic voluntary testing programme, with rates levelling off through 2004.
Conclusions
HIV incidence among MSM appears to have stabilised at a plateau following several years of resurgence. Increases in the selection of sexual partners of concordant HIV serostatus may be contributing to the stabilisation of the epidemic. However, current incidence rates of STI and HIV remain high. Moreover, a strategy of risk reduction by HIV serosorting can be severely limited by imperfect knowledge of one's own and one's partners' serostatus.

25.  A pilot cohort study to assess the feasibility of HIV prevention science research among men who have sex with men in Dakar, Senegal 
Journal of the International AIDS Society  2013;16(4Suppl 3):18753.
Introduction
Men who have sex with men (MSM) are disproportionately burdened by HIV in Senegal, across sub-Saharan Africa and throughout the world. This is driven in part by stigma, and limits health achievements and social capital among these populations. To date, there is a limited understanding of the feasibility of prospective HIV prevention studies among MSM in Senegal, including HIV incidence and cohort retention rates.
Methods
One hundred and nineteen men who reported having anal sex with another man in the past 12 months were randomly selected from a sampling frame of 450 unique members of community groups serving MSM in Dakar. These men were enrolled in a 15-month pilot cohort study implemented by a community-based partner. The study included a structured survey instrument and biological testing for HIV, syphilis and hepatitis B virus at two time points.
Results
Baseline HIV prevalence was 36.0% (43/114), with cumulative HIV prevalence at study end being 47.2% (51/108). The annualized incidence rate was 16% (8/40 at risk for seroconversion over 15 months of follow-up, 95% confidence interval 4.6–27.4%). Thirty-seven men were lost to follow up, including at least four deaths. Men who were able to confide in someone about health, emotional distress and sex were less likely to be HIV positive (OR 0.36, p < 0.05, 95% CI 0.13, 0.97).
Conclusions
High HIV prevalence and incidence, as well as mortality in this young population of Senegalese MSM indicate a public health emergency. Moreover, given the high burden of HIV and rate of incident HIV infections, this population appears to be appropriate for the evaluation of novel HIV prevention, treatment and care approaches. Using a study implemented by community-based organizations, there appears to be feasibility in implementing interventions addressing the multiple levels of HIV risk among MSM in this setting. However, low retention across arms of this pilot intervention, and in the cohort, will need to be addressed for larger-scale efficacy trials to be feasible.
