Abstract

Men who have sex with men (MSM) account for approximately half of Canada’s new HIV infections. Pre-exposure prophylaxis (PrEP), a recently established and effective HIV prevention tool for MSM is currently not approved nor publicly funded. We recruited MSM via respondent-driven sampling to complete a self-administered computer-based interview. Stratified by HIV status, multivariable logistic regression identified factors associated with PrEP awareness. Of 673 participants, 102/500 (20.9%) HIV-negative and 63/173 (26.5%) HIV-positive men were aware of PrEP, but none had used it. One third of PrEP-aware MSM spoke about it with friends or sex partners. Self-declared knowledge was limited. Factors associated with PrEP awareness varied by HIV status, but included greater HAART optimism for HIV-negative MSM. Among HIV-negative MSM, being PrEP unaware was associated with younger age, not always having condoms, and preferring receptive versus insertive anal sex. Future longitudinal research should identify early adopters of PrEP and its associated impacts.
