Examining potential effects of non-occupational post-exposure prophylaxis (nPEP) on sexual behaviors of Chinese men who have sex with men: a cross-sectional study.

These findings identify a high-risk subgroup of MSM, who reported they would use condoms less and/or have more sexual partners when nPEP becomes available. This subgroup of MSM might benefit from targeted health interventions. Moreover, there is a clear discrepancy between anticipated individual and population behavioral changes regarding future routinization of nPEP services, suggesting incorporating nPEP services as a means of community development for MSM.
