Perceived risk for HIV acquisition among gay, bisexual, and other men who have sex with men (GBMSM) may not align with their actual sexual HIV exposure. Factors associated with low/moderate perceived risk among GBMSM eligible for pre-exposure prophylaxis (PrEP) (based on their high estimated HIV exposure) have been poorly described in Latin America. This is a secondary analysis of a 2018 web-based cross-sectional survey in Brazil, Mexico, and Peru. Participants were ≥ 18 years old, cisgender men, not living with HIV, had sex with other men in the previous six months, and had an HIV Incidence Risk Index for MSM score ≥ 10. We performed a multivariable logistic regression to identify factors associated with low/moderate perceived risk for HIV acquisition for each country. A total of 9900 GBMSM were included, and the majority (85.7%) reported low/moderate perceived risk for HIV acquisition. The mean age was 28.8 (SD = 7.7) years, and 77.7% had high school or more. Having ≥ 5 sex partners, daily use of geosocial networking (GSN) apps, and having sex (including condomless insertive anal sex) with a person living with HIV decreased the odds of low/moderate perceived risk for HIV acquisition, but an HIV test in the last year increased the odds only in Mexico. Latin GBMSM with high sexual HIV exposure (eligible to use PrEP) showed a massive gap with their perceived risk. HIV prevention counseling should explore HIV testing history and the frequency of use of GSN apps to promote an objective self-assessment of HIV exposure among Latin GBMSM.
男同性恋者、双性恋者及其他与男性发生性行为的男性（GBMSM）中，感知到的感染艾滋病毒风险可能与他们实际的性接触感染艾滋病毒风险不一致。在拉丁美洲，符合暴露前预防（PrEP）条件（基于其估计的高艾滋病毒暴露风险）的GBMSM中，与低/中度感知风险相关的因素鲜有描述。这是对2018年在巴西、墨西哥和秘鲁开展的一项基于网络的横断面调查的二次分析。参与者年龄≥18岁，为顺性别男性，未感染艾滋病毒，在过去六个月内与其他男性发生过性行为，且男男性行为者艾滋病毒感染风险指数得分≥10。我们进行了多变量逻辑回归分析，以确定每个国家与低/中度感知艾滋病毒感染风险相关的因素。共纳入9900名GBMSM，大多数（85.7%）报告称其感知到的艾滋病毒感染风险为低/中度。平均年龄为28.8岁（标准差=7.7），77.7%的人拥有高中及以上学历。有≥5个性伴侣、每天使用地理社交网络（GSN）应用程序以及与艾滋病毒感染者发生性行为（包括无保护插入式肛交）会降低低/中度感知艾滋病毒感染风险的几率，但去年进行艾滋病毒检测仅在墨西哥会增加这种几率。拉丁美洲有高性接触感染艾滋病毒风险（符合使用PrEP条件）的GBMSM在其感知风险方面存在巨大差距。艾滋病毒预防咨询应探讨艾滋病毒检测史和GSN应用程序的使用频率，以促进拉丁美洲GBMSM对自身艾滋病毒暴露情况进行客观的自我评估。
