Awareness and Perceived Effectiveness of HIV Treatment as Prevention Among Men Who Have Sex with Men in New York City

Original Paper


To assess perceptions of HIV treatment as prevention (TasP), we conducted an online survey of MSM in New York City (n = 732) asking them to rate the effectiveness of different strategies to reduce HIV risk during serodiscordant condomless anal sex between men. Only 6.1% reported not knowing what TasP was, with significantly less awareness among non-gay-identified MSM, men with less education, men who reported fewer anal sex partners in the prior 3 months, and HIV-negative/unaware men who had never used PrEP. The strategy most frequently perceived to offer “a lot” or “complete” protection from HIV was daily PrEP (70.0%), followed by TasP (39.1%), intermittent PrEP (16.6%), strategic positioning (15.8%), and withdrawal before ejaculation (10.8%). Men who were HIV positive, who had ever used PrEP, and who identified as gay/homosexual were significantly more likely to see TasP as effective. Further studies should investigate MSM’s apparent skepticism towards TasP.
