BACKGROUND: Persistent high levels of sexually transmitted infection (STI) in Madagascar indicate current prevention strategies are inadequate. STI/HIV prevention based in social venues may play an important role in reaching individuals at risk of infection. We identified venues where people meet sexual partners and measured the need and potential for venue-based prevention. METHODS: Interviews were conducted in 7 Madagascar towns with 1) community informants to identify social venues, 2) individuals socializing at a sample of venues to assess sexual behavior among venue patrons, and 3) venue representatives to assess the potential for venue-based intervention. RESULTS: Community informants identified numerous venues (range: 67-211 venues, depending on the town); streets, bars, and hotels were most commonly reported. Among 2982 individuals socializing at venues, 78% of men and 74% of women reported new sexual partnership or sex trade for money, goods, or services in the past 4 weeks and 19% of men and 18% of women reported symptoms suggestive of STI in the past 4 weeks. STI symptom levels were disproportionately high among respondents reporting either sex trade or new sexual partnership in the past 4 weeks. Twenty-eight percent of men and 41% of women reported condom use during the last sex act with a new partner. Although 24% to 45% of venues had hosted STI/HIV interventions, interventions were deemed possible at 73% to 90% venues according to 644 interviews with venue representatives. CONCLUSIONS: Venue-based intervention is possible and would reach a spectrum of populations vulnerable to STI/HIV including sex workers, their clients, and other high-risk populations.

PURPOSE: Incarceration may contribute to HIV transmission by disrupting stable partnerships and promoting high-risk partnerships. We investigated incarceration and high-risk partnerships among African Americans in North Carolina. METHODS: We conducted a weighted analysis using the North Carolina Rural Health Project (N = 320), a population-based case-control study of HIV among African Americans. We measured associations between timing and duration of incarceration and high-risk partnerships (multiple partnerships or sex trade for money or drugs). RESULTS: Duration of incarceration appeared to be more important than how long ago incarceration occurred. After adjustment for sociodemographic indicators, high-risk partnerships were associated with short-term (<1 month) incarceration of the respondent versus no respondent incarceration (men: adjusted prevalence ratio (aPR) 1.9, 95% confidence interval (95% CI) 1.2-2.8; women: aPR 3.1, 95% CI 1.2-8.3). High-risk partnerships also were associated with incarceration of a partner versus no partner incarceration (men: aPR 1.8, 95% CI 1.1-3.0; women: aPR 2.0, 95% CI 1.1-3.8). Among men, associations remained when adjusting for substance use. Among women, adjustment for substance use weakened estimates due to the strong correlation between substance use and incarceration. CONCLUSIONS: HIV-prevention programs targeting currently and formerly incarcerated individuals and their partners may decrease HIV in African American communities with high incarceration rates.

This study compared HIV-related sexual behavior among mobile and non-mobile populations in Burkina Faso and identified venues where HIV/AIDS interventions targeting mobile individuals should be implemented. Men (N = 940) and women (N = 430) responded to a sexual behavior survey while socializing at venues where people meet sexual partners in eight Burkina Faso villages. Mobile women were more likely than non-mobile women to report new sexual partnerships (adjusted prevalence odds ratio (POR): 2.07, 95% confidence interval (CI): 1.19-3.59) and transactional sex (adjusted POR: 2.30, 95% CI: 1.55-3.42) in the past month. Mobility was most common and associations between mobility and sexual partnership levels were particularly strong among women interviewed in urban commercial towns situated near international borders. Mobile women were most likely to be interviewed at venues such as bars and clubs, making these appropriate locations for HIV/AIDS interventions. Mobility was not associated with HIV-related sexual behaviors among men.

Incarceration is strongly associated with HIV infection and may contribute to viral transmission by disrupting stable partnerships and promoting high-risk partnerships. We investigated incarceration and STI/HIV-related partnerships among a community-based sample recruited for a sexual behavior interview while frequenting venues where people meet sexual partners in a North Carolina city (N = 373). Men reporting incarceration in the past 12 months were more likely than men without recent incarceration to experience multiple new sexual partnerships (unadjusted prevalence ratio [PR] 1.8, 95% confidence interval [CI]: 1.1-3.1) and transactional sex defined as trading sex for money, goods, or services (unadjusted PR: 4.0, 95% CI: 2.3-7.1) in the past 4 weeks. Likewise, women who were ever incarcerated were more likely than never-incarcerated women to experience recent multiple new partnerships (unadjusted PR: 3.1, 95% CI: 1.8-5.4) and transactional sex (unadjusted PR: 5.3, 95% CI: 2.6-10.9). Sexual partnership in the past 12 months with someone who had ever been incarcerated versus with partners with no known incarceration history was associated with recent multiple new partnerships (men: unadjusted PR 2.0, 95% CI 1.4-2.9, women: unadjusted PR 4.8, 95% CI 2.3-10.1) and transactional sex (men: unadjusted PR 3.3, 95% CI 1.7-6.6, women: unadjusted PR 6.1, 95% CI 2.4-15.4). Adjustment for demographic and socioeconomic variables had minimal effect on estimates. However, the strong overlap between incarceration, partner incarceration, and substance abuse had substantial effects in multivariable models. Correctional-facility and community-based HIV prevention, with substance abuse treatment, should reach currently and formerly incarcerated individuals and their sexual partners.
