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（男男性行为者）中感染艾滋病毒/艾滋病的比例过高。本研究在巴西使用GSN应用程序评估了年龄（18-24岁，25-35岁，>= 36岁）的PrEP意识，其相关因素以及MSM使用艾滋病毒预防技术的意愿。纳入标准为18岁，顺性别男性，hiv阴性血清状态。在7242人中，有4136人（57%）完成了问卷调查。51%的人（18-24岁和36岁的男男性接触者中PrEP意识较低），其相关因素是家庭收入较高，大多数朋友有同性取向，男性性伴侣数量较多以及吸食大麻。艾滋病毒检测（从未与至少一次）导致PrEP意识的几率增加近3倍。只有18-24岁的男男性接触者认识到艾滋病毒风险较高，才提高了对预防措施的认识。共有2335人（56%）愿意每天口服PrEP。巴西对PrEP的认识仍然很低，移动工具是接触男男性行为者和提高对预防技术认识的关键策略。以社区为基础的干预可以增加在线活动，以接触最脆弱的人群，其中包括年轻人、非白人和低收入的男男性行为者。
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.
