Sources of Information about Pre-Exposure Prophylaxis (PrEP) and Associations with PrEP Stigma, Intentions, Provider Discussions, and Use in the United States

Abstract

ABSTRACT The amount and type of information individuals receive about HIV pre-exposure prophylaxis (PrEP) may influence PrEP uptake. We surveyed 331 HIV-negative sexual and gender minorities who have sex with men at a Midwestern Pride festival in 2018 (M age = 32, 68% White, 87% cisgender men) to assess sources and perceived tone of PrEP information and associated outcomes. Most participants (88%) had heard about PrEP. The most common sources were the internet (70%), social media (59%), and friends (54%). Messages from health campaigns were perceived as most positive and those from religious institutions as least positive. Sources differed based on demographics. Controlling for indications for PrEP use, those who heard about PrEP from health campaigns and those who heard more positive messages reported lower levels of PrEP stigma, βs = −0.27––0.23, ps < .05. Non-users who heard about PrEP from the internet had stronger intentions to use PrEP, β = 0.28, p < .05. Those who heard about PrEP from sexual partners and health campaigns were more likely to discuss PrEP with providers, PRs = 1.60–1.80, ps < .01. Finally, those who heard about PrEP from friends and partners were more likely to use PrEP, PRs = 2.01–2.24, ps < .05. Leveraging sexual partners, social network members, and health campaigns are promising avenues to advance PrEP implementation.
