Predictors of unprotected anal intercourse among HIV-positive Latino gay and bisexual men

This study examined sexual behaviors in a sample of 155 HIV-positive Latino gay and bisexual men. Nearly half the sample had engaged in unprotected anal intercourse in the past 12 months; unprotected anal intercourse was more likely when the partner was also HIV-positive. Separate regression models predicted the number of receptive and insertive partners for unprotected anal intercourse. Participants reported both more unprotected insertive and receptive partners if they had sex under the influence of alcohol or drugs. Older participants and those with lower levels of Latino acculturation reported having more partners with whom they took the receptive role during unprotected anal intercourse, whereas those with higher levels of depression reported having more partners with whom they took the insertive role. Hierarchical set logistic regression revealed that the dyadic variable of seroconcordance added to the prediction of unprotected anal sex with the most recent male partner, beyond the individual characteristics. Results show the importance of examining both individual and dyadic characteristics in the study of sexual behavior.
