Abstract

HIV pre-exposure prophylaxis (PrEP) is an effective prevention tool being scaled up in Canada. We describe PrEP uptake and identify demographic correlates of uptake among gay, bisexual, and other men who have sex with men (gbMSM) at elevated HIV risk using data from an online survey of gbMSM residing in Canada between Oct 2017 and Jan 2018. Among the 969 participants at elevated HIV risk who had recently tested for HIV, 96.0%, 83.3%, 72.6%, and 39.7% reported awareness, knowledge, acceptability, and pursuit of PrEP, respectively; 27.1% had ever and 24.6% were currently taking PrEP. The strongest correlate of PrEP uptake was living in a city of ≥ 500,000 inhabitants; others included being out to all or almost all family, friends, and colleagues regarding sexual attraction to men, greater financial coping, and being 30–49 years of age. Improved upscaling of PrEP in Canada may be accomplished through consideration of these disparities.
