Pre-exposure prophylaxis use, HIV knowledge, and internalized homonegativity among men who have sex with men in Brazil: A cross-sectional study

BACKGROUND: Pre-exposure prophylaxis (PrEP) use in Brazil remains low despite free national access. We explored associations of HIV knowledge and internalized homonegativity with PrEP use among PrEP-eligible men who have sex with men (MSM). METHODS: Brazilian Hornet users completed an online, cross-...

description BACKGROUND: Pre-exposure prophylaxis (PrEP) use in Brazil remains low despite free national access. We explored associations of HIV knowledge and internalized homonegativity with PrEP use among PrEP-eligible men who have sex with men (MSM). METHODS: Brazilian Hornet users completed an online, cross-sectional survey in February–March 2020. We included cis-men ≥18 years old who reported recent sex with men and were PrEP-eligible per the following: condomless anal intercourse, partner(s) living with HIV, transactional sex, and/or sexually transmitted infection. Our outcome was current PrEP use, defined by the response, “I am currently taking PrEP.” Key predictors included the HIV/AIDS Knowledge Assessment (HIV-KA) and Reactions to Homosexuality Scale (RHS); higher scores indicate greater knowledge and greater internalized homonegativity, respectively. Scales were standardized for analysis. Associations with current PrEP use were estimated using adjusted odds ratios (aOR) with 95% confidence intervals (95%CI). FINDINGS: Among 2398 PrEP-eligible MSM, n = 370 (15·4%) reported current PrEP use. Increasing HIV-KA scores were associated with greater odds of PrEP use (aOR 1·70 [95%CI 1·41–2·04], p < 0·001), and increasing RHS scores with lower odds of PrEP use (aOR 0·83 [95%CI 0·73–0·96], p = 0·010). PrEP use was lower among 18–24 versus 40+-years-old MSM (aOR 0·43 [95%CI 0·27–0·69], p = 0·005), and in Black versus White/Asian respondents (aOR 0·51 [95%CI 0·31–0·85], p = 0·040). INTERPRETATION: Among PrEP-eligible Brazilian MSM, HIV knowledge was associated with increased PrEP use and internalized homonegativity with decreased use. Wider dissemination of HIV prevention knowledge and addressing stigma experienced by MSM could promote increased PrEP use.

Introdução: O número de usuários da profilaxia pré-exposição (PrEP) no Brasil continua baixo, apesar do acesso gratuito pelo Sistema Único de Saúde. Exploramos as associações entre conhecimento sobre HIV e homonegatividade internalizada com o uso de PrEP entre homens que fazem sexo com homens (HSH) elegíveis para PrEP. Métodos: Brasileiros usuários do Hornet completaram uma pesquisa seccional online em fevereiro-março de 2020. Foram incluídos homens cis ≥18 anos, que reportaram sexo recente com homens e elegíveis para PrEP. O desfecho principal foi uso de PrEP, definido por: "Estou atualmente tomando PrEP." Os principais preditores incluíram escalas de Conhecimento em HIV/aids (HIV-KA) e de Reações à Homossexualidade (RHS); escores mais altos indicam maior conhecimento e maior homonegatividade internalizada, respectivamente. As escalas foram padronizadas para análise. Associações com uso da PrEP foram estimadas usando razões de chances ajustadas (aOR) com intervalos de confiança de 95% (IC95%). Resultados: Entre 2.398 HSH elegíveis para PrEP, 370 (15,4%) relataram o uso atual de PrEP. Maior conhecimento em HIV/AIDS foi associado a maior chance de uso de PrEP (aOR 1·70 [IC 95% 1·41–2·04], p < 0·001), e maior homonegatividade internalizada com menor chance de uso de PrEP (aOR 0·83 [95% IC 0·73–0·96], p = 0·010). Uso de PrEP foi menor entre HSH de 18-24 vs. 40+ anos (aOR 0·43 [IC95%:0·27–0·69], p = 0·005), e entre pretos versus brancos/asiáticos (aOR 0·51 [IC95% 0·31–0·85], p = 0·040). Interpretação: Entre brasileiros HSH elegíveis para a PrEP, o conhecimento do HIV foi associado ao aumento do uso da PrEP e homonegatividade internalizada com a diminuição do uso.
