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

摘要

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% aecurrency24 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.
