Prevalence of condomless anal intercourse and associated risk factors among men who have sex with men in Bamako, Mali.

BACKGROUND: Men who have sex with men (MSM) are disparately impacted by HIV in sub-Saharan Africa and condomless anal intercourse (CAI) is a major driver of HIV transmission. The objective of the current study was to identify factors associated with CAI among MSM in Bamako, Mali, among whom HIV prevalence was 13.7%. METHODS: A bio-behavioral survey was conducted between October 2014 and February 2015 using respondent-driven sampling to recruit 552 adult MSM. Weighted statistical analyses were conducted to determine the prevalence of CAI with one's most recent male partner and survey logistic procedures were used to identify associated factors. RESULTS: The prevalence of CAI with one's most recent male partner was 40.7%. Associated factors included: inability to get a condom when needed (aOR = 5.8, 95%CI: 2.7-12.3) and believing CAI is acceptable under some circumstances (aOR = 8.4, 95%CI: 4.4-16.2). CONCLUSIONS: Programs addressing HIV among MSM in Mali should aim to increase access to condoms and education about HIV prevention through consistent condom use during anal intercourse.

An urgent need for HIV testing among men who have sex with men and transgender women in Bamako, Mali: Low awareness of HIV infection and viral suppression among those living with HIV.

Despite the high HIV prevalence among men who have sex with men (MSM) and transgender women (TGW), there are limited data on progress on their respective HIV antiretroviral treatment (ART) cascades to identify progress and gaps in meeting UNAIDS 90-90-90 targets. We conducted a respondent-driven sampling survey of MSM and TGW in Bamako, Mali from October 2014 to February 2015. We describe the HIV treatment cascade for MSM and TGW, identify correlates of being unaware of HIV-infected status and having unsuppressed viral load levels, and estimate proportion of recent infections. We enrolled 387 MSM and 165 TGW. HIV prevalence was 13.7%. Of those living with HIV, 10.4% were aware of their serostatus, 61.2% of them self-reported being on treatment, and of them, 100% were virally suppressed. In multivariate analysis, factors associated with being unaware of HIV infection included not using free condoms in the last six months (aOR: 5.7, 95% CI: 1.1-29.5) and not having comprehensive knowledge of HIV (aOR: 6.5, 95% CI: 1.4-29.9). Having unsuppressed viral load was associated with identifying as a transgender woman (aOR: 4.8, 95% CI: 1.1-20.7) and not having comprehensive knowledge of HIV (aOR: 6.5, 95% CI: 1.0-40.9). Of the 79 HIV-positive participants, 5.1% had recent infections. While the proportion aware of their HIV status was low despite adjusting for viral load biomarkers, all MSM and TGW on treatment were virally suppressed. Improved testing strategies are urgently needed to achieve the first 90 of the HIV cascade among MSM and TGW in Bamako.

HIV Prevalence and Related Risk Factors in Men Who Have Sex with Men in Bamako, Mali: Findings from a Bio-behavioral Survey Using Respondent-Driven Sampling.

Using respondent driven sampling, we conducted a cross-sectional bio-behavioral survey among men who have sex with men (MSM) in Bamako, Mali. Eligibility criteria included age ≥18 years and having had sex with another man in the last 6 months. We enrolled 552 MSM, 99.6% were tested for HIV. MSM in Bamako were young (69.6% ≤24 years) and educated (63.7% ≥secondary). HIV prevalence among MSM in Bamako was 13.7; 90.1% of HIV-infected men were unaware of their HIV status. Almost one-third had never been tested for HIV. Factors associated with higher odds of HIV included younger age, being receptive with last partner, condom breaking during anal sex in last 6 months, talking to peer educator about HIV, and having sexually transmitted infection symptoms in past year. The results suggest the need for enhanced HIV prevention and treatment services targeted at MSM in Bamako, with emphasis on repeated HIV testing.

High Prevalence of Concurrent Male-Male Partnerships in the Context of Low Human Immunodeficiency Virus Testing Among Men Who Have Sex With Men in Bamako, Mali.

BACKGROUND: Concurrent male-male sexual partnerships have been understudied in sub-Saharan Africa and are especially important because human immunodeficiency virus (HIV) prevalence and acquisition probability are higher among men who have sex with men (MSM) than among heterosexual men and women. METHODS: We conducted a respondent-driven sampling survey of 552 men who have sex with men in Bamako, Mali from October 2014 to February 2015. Eligibility criteria included 18 years or older, history of oral or anal sex with another man in the last 6 months, residence in or around Bamako in the last 6 months, ability to communicate in French. RESULTS: HIV prevalence was 13.7%, with 86.7% of MSM with HIV unaware of their infection. Concurrent male-male sexual partnerships were common, with 60.6% of MSM having a concurrent male sexual partnerships or believing their sex partner did in the last 6 months, and 27.3% having a concurrent male sexual partnerships and believing their sex partner did in the last 6 months. Over half (52.5%) of MSM had sex with women, and 30.8% had concurrent male partnerships and sex with a woman in the last 6 months. Concurrency was more likely among MSM with limited education, telling only MSM of same-sex behaviors, high social cohesion, and not knowing anyone with HIV. CONCLUSIONS: The high proportion of HIV-infected MSM in Bamako who are unaware of their HIV infection and the high prevalence of concurrent partnerships could further the spread of HIV in Bamako. Increasing testing through peer educators conducting mobile testing could improve awareness of HIV status and limit the spread of HIV in concurrent partnerships.
