Despite the major benefits of effective antiretroviral therapy (ART) on HIV-related survival, there is an ongoing need to help alleviate medication side effects related to ART use. Initial studies suggest marijuana use may reduce HIV-related symptoms, but medical marijuana use among HIV-infected individuals has not been well described.
We evaluated trends in marijuana use and reported motivations for use among 2,776 HIV-infected women in the Women’s Interagency HIV Study (WIHS) between October 1994 and March 2010. Predictors of any and daily marijuana use were explored in multivariate logistic regression models clustered by person using GEE. In 2009 participants were asked if their marijuana use was medical, “meaning prescribed by a doctor”, or recreational, or both.
Over the sixteen years of this study the prevalence of current marijuana use decreased significantly from 21% to 14%. In contrast, daily marijuana use almost doubled from 3.3% to 6.1% of all women, and from 18% to 51% of current marijuana users. Relaxation, appetite improvement, reduction of HIV-related symptoms, and social use were reported as common reasons for marijuana use. In 2009, most marijuana users reported either purely medicinal use (26%) or both medicinal and recreational usage (29%). Daily marijuana use was associated with higher CD4 cell count, quality of life, and older age. Demographic characteristics and risk behaviors were associated with current marijuana use overall, but were not predictors of daily use.
This study suggests that both recreational and medicinal marijuana use are relatively common among HIV-infected women in this U.S.

To estimate trends in contraceptive use, especially long-acting reversible contraceptives (LARC) and condoms, among human immunodeficiency virus (HIV)-seropositive and HIV-seronegative women.
HIV-seropositive and HIV-seronegative women in a multicenter longitudinal cohort were interviewed semiannually between 1998 and 2010 about sexual behaviors and contraceptive use. Trends in contraceptive use by women aged 18–45 years who were at risk for unintended pregnancy but not trying to conceive were analyzed using generalized estimating equations.
Condoms were the dominant form of contraception for HIV-seropositive women and showed little change across time. Fewer than 15% of these women used no contraception. Between 1998 and 2010, LARC use rose among HIV-seronegative women from 4.8% (6/126) to 13.5% (19/141, p=0.02), but not significantly among seropositive women (0.9% (4/438) to 2.8% (6/213, p = 0.09). Use of highly effective contraceptives, including pills, patches, rings, injectable progestin, implants and intrauterine devices, ranged from 15.2% (53/348) in 1998 to 17.4% (37/213) in 2010 (p = 0.55). HIV-seronegative but not seropositive LARC users were less likely than nonusers to use condoms consistently (HR=0.51, 95% C.I. 0.32–0.81, p = 0.004 for seronegative women; HR = 1.09, 95% C.I. 0.96, 1.23 for seropositive women).
Although most HIV-seropositive women use contraception, they rely primarily on condoms and have not experienced the increase in LARC use seen among seronegative women. Strategies to improve simultaneous use of condoms and LARC are needed to minimize risk of unintended pregnancy as well as HIV transmission and acquisition of sexually transmitted infections.
To assess the impact of knowledge of cervical cancer biology and prevention as well as noncognitive measures on compliance with colposcopy referral in a high risk population.
Participants in a U.S. cohort of women with human immunodeficiency virus (HIV) and at risk comparison women completed behavior questionnaires and instruments measuring knowledge of cervical cancer prevention, depressive symptoms, trust in doctors, and perceived stress. Examinations including Pap tests also were conducted. Associations with compliance with resulting indicated colposcopy were assessed in multivariable models.
Of 326 women with indicated colposcopy, 222 (68%) were compliant with colposcopy referral and 104 (32%) noncompliant. In multivariable analysis, better colposcopy compliance was associated with less education (O.R. for compliance 2.24, 95% C.I. 1.12–4.51 vs more than high school), prior abnormal Pap (O.R. per prior abnormal Pap 1.08 95% C.I. 1.01–1.15), study site (O.R. for site with best vs worst compliance 16.1, 95% C.I. 2.91–88.6), and higher stress (O.R. for Perceived Stress Scale-10 score >16 vs lower 3.25, 95% C.I. 1.45–7.26).
Noncognitive factors and how sites manage abnormal Pap testing affect colposcopy compliance. Educational interventions alone are unlikely to improve colposcopy compliance in similar high-risk populations.

Drug users and HIV-seropositive individuals often show deficits in decision-making; however the nature of these deficits is not well understood. Recent studies have employed computational modeling approaches to disentangle the psychological processes involved in decision-making. Although such approaches have been used successfully with a number of clinical groups including drug users, no study to date has used computational modeling to examine the effects of HIV on decision-making. In this study, we use this approach to investigate the effects of HIV and drug use on decision-making processes in women, who remain a relatively understudied population.
Fifty-seven women enrolled in the Women's Interagency HIV Study (WIHS) were classified into one of four groups based on their HIV status and history of crack cocaine and/or heroin drug use (DU): HIV+/DU+ (n = 14); HIV+/DU− (n = 17); HIV−/DU+ (n = 14); and HIV−/DU− (n = 12). We measured decision-making with the Iowa Gambling Task (IGT) and examined behavioral performance and model parameters derived from the best-fitting computational model of the IGT.
Although groups showed similar behavioral performance, HIV and DU exhibited differential relationship to model parameters. Specifically, DU was associated with compromised learning/memory and reduced loss aversion, whereas HIV was associated with reduced loss aversion, but was not related to other model parameters.
Results reveal that HIV and DU have differential associations with distinct decision-making processes in women. This study contributes to a growing line of literature which shows that different psychological processes may underlie similar behavioral performance in various clinical groups and may be associated with distinct functional outcomes.
Our goal in this study was to examine how Vitamin C interacts with antiretroviral therapy in individuals with HIV. We specifically evaluated how Vitamin C impacts highly active antiretroviral therapy (HAART) adherence and HAART effectiveness as adjudicated by HIV viral loads and CD4 cell counts. Women served as their own controls, comparing periods of Vitamin C usage with periods of non-usage.

Women in the Women’s Interagency HIV Study (WIHS).
Adherence, CD4 count and Viral load.
Our study population was drawn from 2,813 HIV+ participants who contributed 44,588 visits in WIHS from October, 1994 to April, 2009. Among them, there were 1,122 Vitamin C users with 4,954 total visits where use was reported. In the multivariate model adjusting for age, education, race, income, drug use, Vitamin C use order and depression score, there was a 44% increase in the odds of >=95% HAART adherence among participants during their period of Vitamin C use compared to when they were not using Vitamin C (OR=1.44; 95% CI=1.1–1.9; P-value=0.0179). There was an association with Vitamin C usage and CD4 counts on viral loads.
Vitamin C usage appears to be associated with improved adherence. Future Vitamin C studies should target specific HAART drugs, and prospective clinical outcomes.
HIV-distal sensory polyneuropathy (HIV-DSPN) is a common complication of HIV infection, yet race as a potential risk factor is not known.
Between April and October 2009, as part of the NIH Women’s Interagency HIV Study (WIHS), 1414 women, 973 of whom were HIV-infected, were clinically evaluated for peripheral neuropathy. Utilizing available clinical, laboratory, and sociodemographic variables, we conducted a cross-sectional analysis of factors associated with HIV-DSPN. Multivariable logistic regression was used to examine factors independently associated with HIV-DSPN.
36% of HIV-infected women met our definition of HIV-DSPN. 41.3% of African Americans, 34.8% of Whites and 24.7% of Hispanics had DSPN. Age, Hepatitis C-co-infection, and diabetes were each significantly associated with HIV-DSPN. After controlling for age, diabetes, Hepatitis C co-infection, alcohol use, current dideoxy-nucleoside reverse transcriptase inhibitor use, current CD4 count, and plasma HIV viral load, HIV-DSPN was significantly associated with ethnicity; the odds ratio was 1.67 (p=0.001) in African-Americans compared to other racial groups.
The prevalence of HIV-DSPN in women was lower than reported in prior studies. The likelihood of HIV-DSPN was higher in African-Americans compared to other racial groups. HIV-DSPN was more common in those co-infected with Hepatitis C, older individuals, and diabetics. Further prospective studies are needed to explore the relationship between gender, race, and HIV-DSPN, and the mechanistic basis for racial differences.

Previous studies of the association of the C17T polymorphism of the mu opiate receptor gene with substance dependence compared cases with substance dependence to controls and usually found no significant association. However, the studies were limited by small sample size - no study had more than 12 subjects with the TT genotype, a genotype that is rare in white and Asian subjects. Moreover, drug use is not dichotomous but follows a spectrum from non-use to modest, intermittent use, to use several times daily. We asked whether the Kreek-McHugh-Schluger-Kellogg (KMSK) scales for alcohol, cocaine, opiates, and tobacco that quantify substance use during the time of a subject's maximal use might be more sensitive measures than dichotomous outcomes. We administered the KMSK scales and completed C17T genotyping on 1009 HIV-infected and 469 HIV-uninfected women in The Women's Interagency HIV Study (WIHS), an ongoing study of HIV in women. Forty-two of 697 African-American, 1 of 182 Hispanic, and none of 161 white women had the TT genotype. KMSK cocaine, alcohol, and tobacco scores were significantly higher in African-American women with the TT genotype (p =0.008, 0.0001, and 0.006 respectively) but opiate scores were not. Ordinal regression models controlling for HIV-serostatus, age, education, and income had odds ratios for the TT genotype for predicting alcohol, tobacco, cocaine, and opiates scores of 2.1 (p = 0.02), 2.4 (p = 0.0004), 2.0 (p = 0.03), and 1.9 (p = 0.07). We conclude that the TT genotype of OPRM1 may increase the risk of substance use and abuse.

Human papillomavirus (HPV) is an important risk factor for oropharyngeal cancer. Individuals with human immunodeficiency virus (HIV) have higher oral HPV prevalence but the risk factors for oral HPV infection are not well understood for either HIV-positive or HIV-negative individuals.
This study was nested within the MACS (men) and WIHS (women) cohorts. Exfoliated oral epithelial cells were collected from 379 HIV-positive and 266 at-risk HIV-negative individuals using a rinse and gargle with Scope™ mouthwash. Samples were tested for 36 types of HPV DNA using PGMY09/11 consensus primers and reverse line blot hybridization. Risk factors for oral HPV infection were explored using logistic regression with generalized estimating equations (GEE) in this cross-sectional analysis.
Prevalent oral HPV infection was common (34%), including HPV16 infection in 5.7% of participants. HIV-positive individuals had increased odds of prevalent oral HPV infection compared to HIV-negative individuals (aOR=2.1, 95%CI=1.6–2.8). Risk factors for prevalent oral HPV differed in HIV-positive and HIV-negative participants. Among HIV-negative individuals, higher number of recent oral sex or rimming partners were strong risk factors for prevalent oral HPV infection (each p-trend<0.01). In contrast, among HIV-positive individuals lower CD4 T-cell count (p-trend<0.001) and higher number of lifetime sexual partners (p-trend=0.03) were strong risk factors.
Oral HPV prevalence was elevated in HIV-positive individuals after controlling for differences in cigarette smoking and sexual behavior, supporting the possibility that HIV may affect the natural history of oral HPV.
Immunosuppression may contribute to increased persistence or progression of oral HPV infection.

Depression is common among HIV-infected women, predicts treatment nonadherence, and consequently may impact vertical transmission of HIV. We report findings from a study evaluating preconception, pregnancy, and postpartum depressive symptoms in HIV-infected vs. at-risk, HIV-uninfected women.
We examined the prevalence and predictors of elevated perinatal (i.e., pregnancy and/or postpartum) depressive symptoms using a Center for Epidemiological Studies-Depression (CES-D) scale score of ≥16 in 139 HIV-infected and 105 HIV-uninfected women (62% African American) from the Women's Interagency HIV Study (WIHS).
The prevalence of elevated perinatal depressive symptoms did not differ by HIV serostatus (HIV-infected 44%, HIV-uninfected 50%, p=0.44). Among HIV-infected women, the strongest predictor of elevated symptoms was preconception depression (odds ratio [OR] 5.71, 95% confidence interval [CI] 2.67-12.19, p<0.001); crack, cocaine, and/or heroin use during preconception was marginally significant (OR 3.10, 95% CI 0.96-10.01, p=0.06). In the overall sample, additional significant predictors of perinatal depression included having multiple sex partners preconception (OR 2.20, 95% CI 1.12-4.32, p=0.02), use of preconception mental health services (OR 2.51, 95% CI 1.03-6.13, p=0.04), and not graduating from high school (OR 1.92, 95% CI 1.06-3.46, p=0.03).
Elevated perinatal depressive symptoms are common among HIV-infected and at-risk HIV-uninfected women. Depressive symptoms before pregnancy were the strongest predictor of perinatal symptoms. Findings underscore the importance of early and ongoing assessment and treatment to ensure low vertical transmission rates and improving postpregnancy outcomes for mothers and children.
Vitamin D deficiency is of increasing concern in HIV-infected persons, because of its reported association with a number of negative health outcomes that are common in HIV. We undertook this study to determine the prevalence and predictors of vitamin D deficiency among a nationally representative cohort of middle-aged, ethnically diverse HIV-infected and uninfected women enrolled in the Women’s Interagency HIV study (WIHS).
Vitamin D testing was performed by Quest Diagnostics on frozen sera using the liquid chromatography/mass spectroscopy (LC-MS) method. Vitamin D deficiency was defined as 25 (OH) D ≤20 ng/ml. Comparisons of continuous and categorical characteristics among HIV-infected and HIV-uninfected women were made by Wilcoxon tests and Pearson chi-squared tests, respectively.
1778 women (1268 HIV+) were studied. 63% had vitamin D deficiency (60% HIV +vs. 72% HIV−; p<0.001). Multivariable predictors of Vitamin D Deficiency were being African American (AOR 3.02), Hispanic (AOR 1.40), Body mass index (AOR 1.43), Age (AOR 0.84), HIV+ (AOR 0.76), Glomerular filtration rate <90/ml/min (AOR 0.94) and WIHS site; Los Angeles (AOR 0.66), Chicago (AOR 0.63). In the HIV+ women multivariate predictors were; undetectable HIVRNA (AOR 0.69), CD4 50–200 cells/mm3 (AOR 1.60), CD4 <50 cells/mm3 (AOR 1.94) and recent Protease Inhibitor use (AOR 0.67).
In this study of over 1700 women in the US, most women with or without HIV infection had low vitamin D levels and African American women had the highest rates of Vitamin D deficiency. An understanding of the role that vitamin D deficiency plays in non-AIDS related morbidities is planned for investigation in WIHS.

Human immunodeficiency virus (HIV)–infected individuals frequently have consumed garlic, a popular complementary supplement. Researchers rarely have studied garlic’s association with antiretroviral therapies, however, even though that association is very relevant clinically.
To examine associations of supplemental use of garlic with highly active antiretroviral treatment (HAART) adherence level and HAART effectiveness (HIV viral load and CD4+ cell counts) in HIV-infected women.
The research team carried out a self-controlled, longitudinal study nested within the Women’s Interagency HIV Study (WIHS). The team used a paired study design that allowed participants to serve as their own controls. The team first identified all of the study’s visits in which the participant self-reported the use of a garlic supplement since her last visit (index visit). Then for each index visit, the team identified a matching visit (a control visit) using the following criteria: (a) the visit must be one for the same participant in which that participant reported no garlic supplementation; (b) the visit must immediately precede the index visit (less than 1 year apart); and (c) at the time of the control visit, the participant must have been using antiretroviral therapy identical to that used at the time of the index visit.
Participants were persons using garlic supplementation who already were participants in the WIHS.
The research team used a logistic regression model to examine the association between garlic supplementation and HAART adherence level. The team used a mixed linear model to examine the association of garlic supplementation with HIV viral load and CD4+ cell counts.
From October 1994 to April 2009, 390 HIV-infected women in the WIHS made 1112 visits at which they reported using garlic supplements. Seventy-seven HIV-infected women using HAART met the research team’s selection criteria and contributed 99 pairs of visits for the study. Among the women who used garlic supplements, 22% were 50 years and older; 58% were black and non-Hispanic; and 23% had less than a high-school education. Neither use of garlic supplementation nor reasons for using garlic supplements were significantly associated with the HAART adherence level, HIV viral load, or CD4+ cell counts; however, “use garlic as needed,” a potential marker of a disease state, was significantly associated with higher viral load (P = .0003).
Short-term garlic supplementation did not impact HAART adherence level, HIV viral load, and CD4+ cell counts.
Serosorting, the practice of selectively engaging in unprotected sex with partners of the same HIV serostatus, has been proposed as a strategy for reducing HIV transmission risk among men who have sex with men (MSM). However, there is a paucity of scientific evidence regarding whether women engage in serosorting. We analyzed longitudinal data on women’s sexual behavior with male partners collected in the Women’s Interagency HIV Study from 2001 to 2005. Serosorting was defined as an increasing trend of unprotected anal or vaginal sex (UAVI) within seroconcordant partnerships over time, more frequent UAVI within seroconcordant partnerships compared to non-concordant partnerships, or having UAVI only with seroconcordant partners. Repeated measures Poisson regression models were used to examine the associations between serostatus partnerships and UAVI among HIV-infected and HIV-uninfected women. The study sample consisted of 1,602 HIV-infected and 664 HIV-uninfected women. Over the follow-up period, the frequency of seroconcordant partnerships increased for HIV-uninfected women but the prevalence of UAVI within seroconcordant partnerships remained stable. UAVI was reported more frequently within HIV seroconcordant partnerships than among serodiscordant or unknown serostatus partnerships, regardless of the participant’s HIV status or types of partners. Among women with both HIV-infected and HIV-uninfected partners, 41% (63 HIV-infected and 9 HIV-uninfected) were having UAVI only with seroconcordant partners. Our analyses suggest that serosorting is occurring among both HIV-infected and HIV-uninfected women in this cohort.

To explore previously reported associations between cervical squamous lesions and psychological measures of stress and depression.
In a multicenter cohort study, HIV infected and seronegative comparison women had Pap tests and completed self-report questionnaires including the Perceived Stress Scale-10 (PSS), which measures perceived stress; the PTSD Civilian Symptom Checklist (PCL-C), which measures symptoms of posttraumatic stress disorder; and the Center for Epidemiologic Studies Depression Scale (CES-D), which measures depressive symptoms.
Median scores were 13 (range 0–38) for the PSS, 24 (range 17–85) for the PCL-C, and 8 (range 0–57), for the CES-D, indicating moderate stress and minimal depression. For PSS, compared to women in the lowest tertile of reported stress, O.R. for SIL was 0.88 (95% C.I. 0.50–1.54) for women in the middle tertile and 0.96 (95% C.I. 0.54–1.68) for women in the highest tertile. For PCL-C, compared to women in the lowest tertile of PTSD symptoms, O.R. for SIL was 0.79 (95% C.I. 0.43–1.41) for women in the middle tertile and 1.17 (95% C.I. 0.68–2.01) for women in the highest tertile. SIL rates were similar for CES-D scores ≥16 (compared to women with lower scores O.R. 1.41, 95% C.I. 0.88–2.26) and ≥ 23 (O.R. 1.39, 95% C.I. 0.81–2.40). In multivariable analysis including number of sexual partners, age, income, ethnicity, and serostatus, stress as measured by PSS and PCL-C, and depressive symptoms as measured by CES-D remained unassociated with SIL.
We found no evidence that stress and depression affect the prevalence of cervical squamous lesions.

To estimate changes in high risk women’s knowledge of cervical cancer prevention, human papillomavirus (HPV), and HPV vaccination since introduction and marketing of HPV vaccines.
At study visits in 2006 and 2008, women with the human immunodeficiency virus (HIV) and at-risk comparison women in a multicenter U.S. cohort study completed 44-item self-report questionnaires exploring their knowledge of cervical cancer prevention, HPV, and HPV vaccination. Results from 2006 were compared to those obtained in 2008. Knowledge scores were correlated with demographic variables, measures of education and attention, and medical factors. Significant associations were assessed in multivariable models.
HIV-seropositive women had higher knowledge scores than seronegative women at baseline (13.2 +/− 5.7 vs 11.8 +/− 6.0, P = 0.0002) and follow-up (14.1 +/− 5.3 vs 13.2 +/− 5.5, P = 0.01), but the change in scores was similar (0.9 +/− 5.3 vs 1.5 +/− 5.5, P = 0.13). Knowledge that cervical cancer is caused by a virus rose significantly (P = 0.005), but only to 24%. Belief that cervical cancer is preventable only rose from 52% to 55% (P = 0.04), but more than 90% of women in both periods believed regular Pap testing was important. In ANCOVA models, higher baseline score, younger age, higher education level, higher income, and former- as opposed to never-drug users, but not HIV status, were associated with improved knowledge.
High-risk women’s understanding of cervical cancer and HPV has improved, but gaps remain. Improvement has been weakest for less-educated and lower-income women.
Two of the most pressing public health challenges in the United States are treating human immunodeficiency virus (HIV) infection and illegal substance use. High rates of complementary and alternative medicine (CAM) use have been reported by individuals who suffer from both of these diseases. The goal of this study was to examine the relationship between CAM use and illegal substance use in a cohort of women with HIV or at risk for HIV disease. Based on previous research, it was hypothesized that CAM use may decrease substance use.
This was a longitudinal cohort study.
The subjects comprised Women in the Women's Interagency HIV Study.
The role of CAM use in illegal substance use was examined. Due to the hierarchical structure of the dataset, logistic regression analysis adjusting for repeated measurements (generalized estimating equation model) was carried out to assess associations of CAM use and illicit drug use.
There were 2176 women included in the analysis. After excluding for marijuana use, CAM use was associated with less drug use (odds ratio 0.82; 95% confidence interval: 0.73, 0.90).
The results supported our hypothesis that CAM users are more health conscious and thus less likely to use illicit drugs. Future studies should target both specific drugs and CAM modalities to help finalize this association.
To assess knowledge of and attitudes towards human papillomavirus (HPV), Pap testing, and the HPV vaccine.
In a multicenter U.S. cohort study, women with the human immunodeficiency virus (HIV) and at-risk comparison women completed 44-item standardized self-report questionnaires exploring their knowledge of cervical cancer prevention, HPV, and HPV vaccination. Results were correlated with demographic variables, measures of education and attention, and medical factors. Data were clustered using principal component analysis. Significant associations were assessed in multivariable models.
Among 1588 women, HIV seropositive women better understood facts about cervical cancer prevention and HPV than seronegative women, but both had substantial knowledge deficits. Almost all women considered Pap testing important, although 53% of HIV seropositive and 48% of seronegative women considered cervical cancer not preventable (P=0.21). Only 44% of HIV seropositive women knew Paps assess the cervix, versus 42% of HIV seronegative women (P=0.57). Both groups understood that HPV causes genital warts and cervical cancer (67% of HIV seropositive vs. 55% of seronegative women, P=0.002). About half of both groups considered HPV vaccination extremely important for cervical cancer prevention. HIV seronegative women were more likely to report learning of HPV vaccination through advertising than from clinicians (81% vs. 64%, P<0.0001).
High risk women need effective education about cervical cancer prevention, HPV, and HPV vaccination.

HIV-associated immune injury is hypothesized to increase the risk of preclinical disability and frailty via inflammatory pathways. We investigated the role of CD4+ T cell depletion and clinical AIDS on preclinical disability and frailty in HIV-positive women with a history of combination antiretroviral therapy (cART) and HIV-negative women.
This was a cross-sectional study nested within the Women's Interagency HIV Study (WIHS), a prospective cohort study initiated in 1994 across five U.S. cities. Questionnaires and tests were performed by 573 HIV-negative and 1206 HIV-positive women. Prevalence ratios were computed using regression models.
Severe CD4+ cell depletion was an independent predictor of slowness, weakness, and frailty in HIV-positive women compared with HIV-negative women. Women with CD4+ counts <100 cells/mm3 were 0.13 seconds slower to complete 4 meters (95% CI 0.06-0.21), 1.25 kg weaker (95% CI −2.31-−0.19), and had 2.7 times higher prevalence of frailty (95% CI 1.46-5.01).
This study is one of the largest studies to administer performance-based tests to investigate disability and frailty in HIV-positive women. HIV-positive women with intact immune systems and without a history of clinical AIDS were no different from HIV-negative women on tests of slowness, weakness, and frailty phenotype.
To determine prevalence and predictors of complementary and alternative medicine (CAM) use disclosure to health care providers and whether CAM use disclosure is associated with highly active antiretroviral therapy (HAART) adherence among HIV-infected women, we analyzed longitudinal data collected between October 1994 and March 2002 from HIV-infected CAM-using women enrolled in the Women's Interagency HIV Study. Repeated measures Poisson regression models were constructed to evaluate associations of selected predictors with CAM use disclosure and association between CAM use disclosure and HAART adherence. A total of 1377 HIV-infected women reported CAM use during study follow-up and contributed a total of 4689 CAM-using person visits. The overall prevalence of CAM use disclosure to health care providers was 36% across study visits. Women over 45 years old, with a college education, or with health insurance coverage were more likely to disclose their CAM use to health care providers, whereas women identified as non-Hispanic Black or other ethnicities were less likely to communicate their CAM usage. More health care provider visits, more CAM domains used, and higher health care satisfaction scores had significant relationships with increased levels of CAM use disclosure. Restricting analysis to use of herbal or nonherbal medications only, similar results were obtained. Compared to other CAM domains, mind–body practice had the lowest prevalence of CAM use disclosure. Additionally, CAM use disclosure was significantly associated with higher HAART adherence. From this study, we showed that a high percentage of HIV-infected women did not discuss their CAM use with health care providers. Interventions targeted towards both physicians and patients may enhance communication of CAM use, avoid potential adverse events and drug interactions, and enhance HAART adherence.
The objective was to assess study retention and attendance for two recruitment waves of participants in the Women's Interagency HIV Study (WIHS).
The WIHS, a prospective study at six clinical centers in the United States, has experienced two phases of participant recruitment. In phase one, women were screened and enrolled at the same time, and in phase two, women were screened and enrolled at separate visits. Compliance with study follow-up was evaluated by examining semiannual study retention and visit attendance.
After 10 study visits, the retention rate in the original recruits (enrolled in 1994–1995) was 83% for the HIV-infected women and 69% for the HIV-uninfected women compared with 86% and 86%, respectively, in the new recruits (enrolled in 2001–2002). In logistic regression analysis of the HIV-infected women, factors associated with early (visits 2 and 3) nonattendance were temporary housing, moderate alcohol consumption, use of crack/cocaine/heroin, having a primary care provider, WIHS site of enrollment, lower CD4 cell count, and higher viral load. Among HIV-uninfected women, the factors associated with early nonattendance were recruitment into the original cohort, household income ≥$12,000 per year, temporary housing, unemployment, use of crack/cocaine/heroin, and WIHS site of enrollment. Factors associated with nonattendance at later visits (7–10) among HIV-infected participants were younger age, white race, not having a primary care provider, not having health insurance, WIHS site of enrollment, higher viral load, and nonattendance at a previous visit. In HIV-uninfected participants, younger age, white race, WIHS site of enrollment, and nonattendance at a previous visit were significantly associated with nonattendance at later visits.
Preventing early loss to follow-up resulted in better study retention early, but late loss to follow-up may require different retention strategies.
We evaluated pain frequency and severity in 339 women enrolled in the Women's Interagency HIV Study (WIHS). Among these, 63% were 39 years of age or younger, 17% were white, 54% African American, and 29% Hispanic; 32% did not complete high school; 58% had a CD4 less than 200; 65% had clinical AIDS; 60% were on highly active antiretroviral therapy (HAART); and 32% had a viral load of 50,000 or more. Data were collected between 1996 and 1998. Within the past 6 months 190 (56%) women experienced pain 6 or more days and 168 (50%) women indicated pain severity scores of 4 or 5 (5-point scale). Pain frequency and pain severity were not associated with age, education, ethnicity, current therapy, or location of the WIHS site. Pain frequency and severity were related to lower CD4 count, higher depression, with a history and longer duration of smoking and use of marijuana. Severity was associated with a history of crack/cocaine or heroin use or with injection drug use as the transmission category. In the multivariate models, pain severity was related to CD4 count and depression and to current tobacco use but not to crack, cocaine, heroin, or marijuana use. Pain frequency was related to depression and to former tobacco, crack, cocaine, heroin, or marijuana use but not to current use. The long-term effects of tobacco use may be to increase pain experience but women may also smoke tobacco or use other substances to give mild pain relief. Pain is frequent and often severe among women with HIV requiring medical management.
Hazardous alcohol consumption among women with human immunodeficiency virus (HIV) infection is associated with several adverse health and behavioral outcomes, but the proportion of HIV-positive women who engage in hazardous drinking over time is unclear. The authors sought to determine rates of hazardous alcohol consumption among these women over time and to identify factors associated with this behavior. Subjects were 2,770 HIV-positive women recruited from 6 US cities who participated in semiannual follow-up visits in the Women's Interagency HIV Study from 1995 to 2006. Hazardous alcohol consumption was defined as exceeding daily (≥4 drinks) or weekly (>7 drinks) consumption recommendations. Over the 11-year follow-up period, 14%–24% of the women reported past-year hazardous drinking, with a slight decrease in hazardous drinking over time. Women were significantly more likely to report hazardous drinking if they were unemployed, were not high school graduates, had been enrolled in the original cohort (1994–1995), had a CD4 cell count of 200–500 cells/mL, were hepatitis C-seropositive, or had symptoms of depression. Approximately 1 in 5 of the women met criteria for hazardous drinking. Interventions to identify and address hazardous drinking among HIV-positive women are urgently needed.

Our objective was to describe the association that childcare burden, household composition, and health care utilization have with adherence to highly active antiretroviral therapy (HAART) among women in the United States. The primary outcome was 95% or more adherence to HAART evaluated at 10,916 semiannual visits between October 1998 and March 2006 among 1419 HIV-infected participants enrolled in the Women's Interagency HIV Study. HAART adherence levels of 95% or more were reported at 76% of the semiannual visits. At only 4% of the person-visits did women report either quite a bit or extreme difficulty in caring for child; at 52% of the person-visits women reported at least one child 18 years of age or older living in the household. We found a one-unit increase in the difficulty in caring for children (childcare burden was assessed on a 5-point scale: not difficult  to extremely difficult ) was associated with a 6% decreased odds of 95% or more HAART adherence (adjusted odds ratio [OR] = 0.94; p = 0.07). Each additional child 18 years of age or less living in the household was associated with an 8% decreased odds of 95% or more adherence (adjusted OR = 0.92, p = 0.03). Both the number and type of adult living in the household, as well as health care utilization were not associated with HAART adherence. Greater child care burden and number of children 18 years old or younger living in household were both inversely associated with HAART adherence. Assessing patients' difficulties in caring for children and household composition are important factors to consider when addressing adherence to HAART.
This article presents a case of a 17-year-old softball pitcher with insidious onset of right forearm pain. On presentation, the patient had tenderness on palpation of the midshaft of the ulna, pain with resisted pronation, and pain with fulcrum-type stressing of the forearm. A bone scan revealed increased uptake in the right ulna, and a subsequent magnetic resonance imaging revealed bone marrow edema and numerous small ulnar stress fractures. She was treated with bone stimulation and complete rest and is in the process of returning to pitching.

To determine prevalence and predictors of complementary and alternative medicine (CAM) use disclosure to health care providers and whether CAM use disclosure is associated with highly active antiretroviral therapy (HAART) adherence among HIV-infected women, we analyzed longitudinal data collected between October 1994 and March 2002 from HIV-infected CAM-using women enrolled in the Women’s Interagency HIV Study. Repeated measures Poisson regression models were constructed to evaluate associations of selected predictors with CAM use disclosure and association between CAM use disclosure and HAART adherence. A total of 1377 HIV-infected women reported CAM use during study follow-up and contributed a total of 4689 CAM-using person visits. The overall prevalence of CAM use disclosure to health care providers was 36% across study visits. Women over 45 years old, with a college education, or with health insurance coverage were more likely to disclose their CAM use to health care providers, whereas women identified as non-Hispanic Black or other ethnicities were less likely to communicate their CAM usage. More health care provider visits, more CAM domains used, and higher health care satisfaction scores had significant relationships with increased levels of CAM use disclosure. Restricting analysis to use of herbal or nonherbal medications only, similar results were obtained. Compared to other CAM domains, mind–body practice had the lowest prevalence of CAM use disclosure. Additionally, CAM use disclosure was significantly associated with higher HAART adherence. From this study, we showed that a high percentage of HIV-infected women did not discuss their CAM use with health care providers. Interventions targeted towards both physicians and patients may enhance communication of CAM use, avoid potential adverse events and drug interactions, and enhance HAART adherence.
