Brazil has the largest population of individuals living with HIV/AIDS in Latin America with a disproportional prevalence of infection among men who have sex with men (MSM). This study evaluated PrEP awareness by age (18-24, 25-35, ≥36 years), its associated factors and the willingness to use HIV prevention technologies among MSM using a GSN app in Brazil. Inclusion criteria were ≥18 years-old, cisgender men and HIV-negative serostatus. Of 7242 individuals, 4136 (57%) completed the questionnaire. PrEP awareness was reported by 51% (though lower among MSM aged 18-24 and ≥36 years) and its associated factors were higher family income, most friends with the same sexual orientation, high number of male sexual partners and marijuana use. HIV testing (never vs. at least once) lead to an almost 3-fold increase in the odds of PrEP awareness. High HIV risk perception led to increased PrEP awareness only among MSM aged 18-24 years. A total of 2335 (56%) was willing to use daily oral PrEP. PrEP awareness remains low in Brazil and mobile tools are key strategies to reach MSM and increase awareness of prevention technologies. Community-based interventions could add to online campaigns to reach the most vulnerable, which include young, non-white and lower-income MSM.
巴西是拉丁美洲感染艾滋病毒/艾滋病人数最多的国家，男男性行为者（MSM）中的感染率不成比例。本研究通过年龄（18 - 24岁、25 - 35岁、≥36岁）评估了巴西男男性行为者对暴露前预防（PrEP）的知晓情况、其相关因素以及使用艾滋病毒预防技术的意愿，这些男男性行为者使用了一款GSN应用程序。纳入标准为年龄≥18岁、生理性别为男且血清学检测为艾滋病毒阴性。在7242名个体中，4136名（57%）完成了问卷。报告知晓PrEP的比例为51%（尽管在18 - 24岁和≥36岁的男男性行为者中比例较低），其相关因素包括家庭收入较高、大多数朋友具有相同性取向、男性性伴侣数量较多以及使用大麻。艾滋病毒检测（从未检测过与至少检测过一次）使知晓PrEP的几率增加了近3倍。高艾滋病毒风险认知仅在18 - 24岁的男男性行为者中导致PrEP知晓率增加。共有2335名（56%）愿意每日口服PrEP。巴西对PrEP的知晓率仍然较低，移动工具是接触男男性行为者并提高预防技术知晓率的关键策略。基于社区的干预措施可以补充在线宣传活动，以覆盖最脆弱人群，其中包括年轻、非白人和低收入的男男性行为者。
