Correlates of unprotected anal sex with casual partners: a study of gay men living in the southern United States.

This study identified demographic and behavioral correlates of engaging in unprotected anal sex (UAS) with non-main partners among men having sex with men (MSM). Just over 1,000 men completed anonymous surveys with 25% of the men reporting their most recent sexual act with a non-main male partner was UAS. These men tended to be white, older, HIV seropositive, and high (or drunk) when having sex. In multivariate analysis being seropositive, and being high or drunk retained significance. Subsequent research may build upon these findings to determine the causal pathway to UAS among MSM having sex with non-main partners. Findings may be useful in constructing prevention interventions for MSM frequenting gay venues.
