High-Risk Behaviors Associated with Injection Drug Use Among Recently HIV-Infected Men Who Have Sex with Men in San Diego, CA.

Published: May 24, 2011


The contribution of injection drug use to HIV risk among men who have sex with men (MSM) is understudied. MSM infected with HIV within the prior 12 months completed a questionnaire assessing sociodemographic, sexual, drug use, and social factors. Analyses were performed to identify factors associated with lifetime history of injection drug use. Among 212 participants, the mean age was 33.8 years, 72% were White, 89% had attended college, and 9.4% reported ever injecting drugs. In multivariable logistic regression analysis, ever trading sex and using methamphetamine during sex with at least one of their last three partners were associated with injection drug use. Adjusting for these variables, in separate models, ever perpetrating violence against others (Adjusted Odds Ratio [AOR] = 3.16), having physically abusive sexual partners (AOR = 3.08), or physically abusing sexual partners (AOR = 10.17) were significantly (P < 0.05) associated with injection drug use. These findings suggest that violence is more common among MSM who inject drugs, which should be considered in HIV prevention efforts.
