Abstract

Data from Medical Monitoring Project was used to determine if partner type is associated with condomless anal sex (CAS) and insertive condomless anal sex (ICAS) among HIV-positive men who have sex with men. Participants reported HIV status and PrEP use of up to five anal sex partners. Partner type was categorized as HIV-positive, HIV status unknown, HIV-negative on PrEP or HIV-negative not on PrEP. To account for correlation of multiple observations per participant, generalized estimating equations were used to calculate adjusted prevalence ratios and 95% confidence intervals of CAS and ICAS. Condom use during anal sex and insertive anal sex varied based on partner type. There was a higher prevalence of CAS and ICAS in partnerships with HIV-positive partners or HIV-negative partners on PrEP compared to HIV-negative partners not on PrEP.
