Factors associated with interest in and knowledge of pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (GBMSM) in the Region of Waterloo, Ontario, Canada: Insights from the OutLook Study.

Pre-exposure prophylaxis (PrEP) is an effective HIV-prevention tool for gay, bisexual, and other men who have sex with men (GBMSM), a group known to be disproportionately affected by HIV/AIDS. We aimed to identify sociodemographic, psychosocial, and health factors associated with awareness of PrEP or interest in PrEP among GBMSM in a mid-sized Canadian city, where PrEP availability is arguably more scarce compared to larger metropolitan regions. The OutLook Study was a comprehensive online survey of LGBTQ health and well-being that collected data from sexual minorities aged 16+ in the Region of Waterloo, Ontario, Canada. Participants were cisgender MSM with an unknown or negative HIV status (n = 203). Bivariate logistic regression was performed to analyze factors associated with both awareness of PrEP and interest in PrEP. Multivariate logistic regression explored sexual behaviours in the past 12 months while controlling for sociodemographic and psychosocial variables. Increasing number of sexual partners (OR: 1.10; 95% CI: 1.03–1.53) was significantly associated with interest in PrEP and lifetime experiences of homophobia remained significant from the bivariate model (ORs ranged from 1.11–1.12). Since GBMSM with low educational attainment were shown to have less knowledge about PrEP, educational campaigns could be targeted in high schools rather than colleges, universities, and trade schools. Prevention initiatives should be aimed at places where single or non-monogamous GBMSM frequent due to these men being disproportionately affected by HIV/AIDS. These findings provide insights for potential interventions targeting MSM from mid-sized cities. [ABSTRACT FROM AUTHOR]
