Community awareness of, use of and attitudes towards HIV pre-exposure prophylaxis (PrEP) among men who have sex with men in Vancouver, Canada: preparing health promotion for a publicly funded PrEP program.

Abstract

Adult MSM were recruited from January to June 2017 through a local community-based organisation's PrEP campaign website (www.getpreped.ca). Participants self-completed an anonymous online questionnaire, and were stratified into three groups: (i) HIV-positive participants; (ii) HIV-negative participants not using PrEP; and (iii) HIV-negative participants using PrEP. Descriptive, bivariate and univariate regression analyses were conducted. Of 249 participants, 191 (77%) were HIV-negative not using PrEP, 41 (17%) were HIV-negative using PrEP and 17 (7%) were HIV-positive. Among PrEP users, 90% used PrEP daily and all reported having recommended medical follow-up care. Among HIV-negative, non-PrEP-users, 44% said they would reduce condom use if they used PrEP and 28% were uncomfortable asking their doctor for PrEP. Interest in PrEP among non-users was associated with higher objective risk scores (i.e. HIV Incidence Risk Index for MSM), higher self-perceived risk, greater perceived PrEP effectiveness, no prescription medications insurance, open or single relationship status (vs closed) and not always using condoms (vs always). Among HIV-positive participants, 53% agreed PrEP reduced stigma for people living with HIV. All study groups perceived a greater percentage of MSM on PrEP (10%, 15%, 18%) than in their own social networks (5%, 4%, 6%). PrEP health promotion must consider comprehensive PrEP education; accuracy of self-perceived HIV risk and PrEP social norms; and barriers to culturally safe primary care for MSM.
