Abstract

Black men who have sex with men (BMSM) and some who also have sex with women (BMSMW) account for over 70% of new HIV infections in the United States representing an elevated HIV risk in this group, also informing risks of HIV transmission to other BMSM and female sexual partners. We examined trajectories of self-reported substance use, HIV-related sexual risk behaviors, and psychosocial vulnerabilities among BMSMW versus BMSM over a 1-year study period. We analyzed baseline, 6-, and 12-month follow-up data from the HIV Prevention Trials Network "BROTHERS" Study (HPTN 061; n = 1126). Categorizing participants by sexual partner type across 3 time points: (1) BMSMO: having male and no female partners across assessments and (2) BMSMW: having sex with male and one or more female partners at least at 1 time point. Using generalized estimating equations, we estimated associations between being BMSMW (versus BMSMO) and changes in psychosocial vulnerability, substance use, and HIV-related sexual risk behaviors. Generalized estimating equation models controlling for sociodemographics, time-varying effects, and intervention status showed that BMSMW versus BMSMO had 50% increased odds of crack use, 71% increased odds of alcohol use during ...Continue Reading
