Background

There are no data available on human papillomavirus (HPV) infections in women living in the Mississippi Delta, where cervical cancer incidence and mortality among African American women is among the highest in the United States. The aim of this analysis was to report the age-specific prevalence of HPV in this population.

Methods

We recruited 443 women, 26–65 years of age, from the general population of women living in the Mississippi Delta to participate; 252 women had been screened for cervical cancer within the last 3 years while 191 had not. Women underwent a pelvic exam and had clinician-collected Pap sample taken for the routine cervical cancer screening by cytology. Women were asked to collect a self-collected specimen at home and return it to the clinic. Both specimens were tested for HPV genotypes.

Results

Four hundred and six women (91.6%) had HPV genotyping results for the clinician-collected and self-collected specimens. The prevalence of carcinogenic HPV was 18.0% (95% CI: 14.4%-22.1%) for clinician-collected specimens and 26.8% (95% CI: 22.6%-31.4%) for self-collected specimens. The concordance for the detection of carcinogenic HPV between clinician-collected and self-collected specimens was only fair (kappa = 0.54). While the prevalence of carcinogenic HPV in either sample decreased sharply with increasing age (ptrend< 0.01), the prevalence of non-carcinogenic HPV did not, especially the prevalence of HPV genotypes in the alpha 3/4/15 phylogenetic group.

Conclusions

The prevalence of carcinogenic HPV in our sample of women living in the Mississippi Delta was greater than the prevalence reported in several other U.S. studies. The high carriage of HPV infection, along with lack of participation in cervical cancer screening by some women, may contribute to the high cervical cancer burden in the region.

Background

Blunts are hollowed-out cigars or leaf tobacco filled with marijuana. Use of blunts has increased since the 1990s and, in 2005, 3.5% of all American youth were estimated to have used blunts in the past month. Blunt smokers may have greater odds of cannabis and tobacco dependency and are at risk of smoking-related diseases. Previous studies have suggested that blunt use is more common among blacks, older teens, and men. However, data pertaining to blunt use in non-adolescent African-American populations are scarce.

Purpose

(1) To assess patterns of blunt use among young adult African-American men aged 19–30 years residing in five rural Black Belt counties in Alabama; (2) To compare these data with those from tobacco cigarette smokers within the same study population.

Methods

Verbal, face-to-face interviewer-administered survey of 415 participants collected and analyzed between December 2008 and February 2011.

Results

159 respondents (38.3%) smoked cigarettes and 45 smoked blunts (10.8%). Of blunt smokers, 33 also smoked cigarettes (73.3%). Use of blunts was prevalent among unemployed, single men, and occupational blunt use was uncommon. Factors important in the initiation, maintenance and cessation of product use were similar for blunt and cigarette smokers, especially product use and acceptance by friends. Legal concerns were an important factor facilitating blunt cessation.

Conclusions

Blunt use is relatively common among male African Americans aged 19–30 years and is frequently associated with concomitant cigarette use. Tobacco control efforts in this male African-American population should also address blunt usage.

Community-based participatory research (CBPR) has been posited as a promising methodology to address health concerns at the community level, including cancer disparities. However, the major criticism to this approach is the lack of scientific grounded evaluation methods to assess development and implementation of this type of research. This paper describes the process of development and implementation of a participatory evaluation framework within a CBPR program to reduce breast, cervical, and colorectal cancer disparities between African Americans and whites in Alabama and Mississippi as well as lessons learned. The participatory process involved community partners and academicians in a fluid process to identify common ground activities and outcomes. The logic model, a lay friendly approach, was used as the template and clearly outlined the steps to be taken in the evaluation process without sacrificing the rigorousness of the evaluation process. We have learned three major lessons in this process: (1) the importance of constant and open dialogue among partners; (2) flexibility to make changes in the evaluation plan and implementation; and (3) importance of evaluators playing the role of facilitators between the community and academicians. Despite the challenges, we offer a viable approach to evaluation of CBPR programs focusing on cancer disparities.

Cervical cancer is the second most common female tumor worldwide and its incidence is disproportionately high (>80%) in the developing world. In the U.S., where Pap tests have reduced the annual incidence to approximately 11,000 cervical cancers, more than 60% of cases occur in medically-underserved populations as part of a complex of diseases linked to poverty, race/ethnicity, and/or health disparities. Because carcinogenic human papillomavirus (HPV) infections cause virtually all cervical cancer, two new approaches for cervical cancer prevention have emerged: 1) HPV vaccination to prevent infections in younger women (≤18 years old) and 2) carcinogenic HPV detection in older women (≥30 years old). Together, HPV vaccination and testing, if used in an age-appropriate manner, have the potential to transform cervical cancer prevention particularly among underserved populations. Yet significant barriers of access, acceptability, and adoption to any cervical cancer prevention strategy remain. Without understanding and addressing these obstacles, these promising new tools for cervical cancer prevention may be futile. We share our experiences in the delivery of cervical cancer prevention strategies to U.S. populations experiencing high cervical cancer burden: African-American women in South Carolina, Alabama, Mississippi; Haitian immigrant women in Miami; Hispanic women in the U.S.-Mexico Border; Sioux/Native American women in the Northern Plains; white women in the Appalachia; and Vietnamese-American women in Pennsylvania and New Jersey. Our goal is to inform future research and outreach efforts to reduce the burden of cervical cancer in underserved populations.

Introduction

Low-income African Americans who live in rural areas of the Deep South are particularly vulnerable to diseases associated with unhealthy energy imbalance. The Centers for Disease Control and Prevention (CDC) has suggested various physical activity strategies to achieve healthy energy balance. Our objective was to conduct formal, open-ended discussions with low-income African Americans in the Mississippi Delta to determine 1) their dietary habits and physical activity levels, 2) their attitudes toward CDC's suggested physical activity strategies, and 3) their suggestions on how to achieve CDC's strategies within their own environment.

Methods

A qualitative method (focus groups) was used to conduct the study during 2005. Prestudy meetings were held with African American lay health workers to formulate a focus group topic guide, establish inclusion criteria for focus group participants, select meeting sites and times, and determine group segmentation guidelines. Focus groups were divided into two phases.

Results

All discussions and focus group meetings were held in community centers within African American neighborhoods in the Mississippi Delta and were led by trained African American moderators. Phase I focus groups identified the following themes: overeating, low self-esteem, low income, lack of physical exercise, unhealthy methods of food preparation, a poor working definition of healthy energy balance, and superficial knowledge of strategies for achieving healthy energy balance. Phase 2 focus groups identified a preference for social support-based strategies for increasing physical activity levels.

Conclusion

Energy balance strategies targeting low-income, rural African Americans in the Deep South may be more effective if they emphasize social interaction at the community and family levels and incorporate the concept of community volunteerism.
