Alcohol use predicts sexual risk behavior with HIV-negative or partners of unknown status among young HIV-positive men who have sex with men.

Although the relationship between substance use and heightened sexual risk behaviors have been documented in samples of young men who have sex with men (YMSM) and HIV-positive adult men who have sex with men (MSM), there is a dearth of research on the role of substance use in the sexual risk behaviors of HIV-positive YMSM. We examined associations between alcohol and other drug use with sexual risk behaviors among a sample of HIV-positive YMSM (N=200). There were no significant predictors of either receptive or insertive unprotected anal intercourse (UAI) with HIV-positive partners among the substance use variables. Failure to use a condom after drinking alcohol (β=2.00, p<0.01) was significantly associated with insertive UAI with HIV-negative partners or partners of unknown status. Failure to use a condom after drinking alcohol (β=1.36, p<0.05) and age (β=0.35, p<0.05) were significantly associated with receptive UAI with HIV-negative partners or partners of unknown status. Findings from this article underscore the role of alcohol in facilitating UAI among HIV-positive YMSM and their HIV-negative and status-unknown partners.
