The aim of this study was to estimate the prevalence and factors associated with unprotected receptive anal intercourse (URAI), stratified by age (18-24 or 25 + years old), in a sample of 4,129 MSM recruited by respondent driven sampling in 12 Brazilian cities in 2016. The prevalence of URAI was higher among younger MSM (41.9% vs 29.7%) (p < 0.01). Multivariate analysis indicated that perception of risk, sexual identity, self-rated health status, and having commercial sex were associated with URAI among younger MSM. History of sexual violence, sex with younger partners, having 6 + partners and unprotected sexual debut were associated with URAI among older MSM. Marital status, having stable partner, and reporting sex with men only were associated with URAI in both groups. Despite access to condoms and lubricants, preventive efforts may not be reaching MSM effectively. Age specific intervention approaches, including stigma, discrimination, and perception of risk must be considered.
本研究旨在估计2016年在巴西12个城市通过应答者驱动抽样招募的4129名男男性行为者样本中，按年龄（18 - 24岁或25岁及以上）分层的无保护被动肛交（URAI）的患病率及相关因素。年轻男男性行为者中URAI的患病率更高（41.9%对29.7%）（p < 0.01）。多变量分析表明，风险认知、性取向、自评健康状况以及有商业性行为与年轻男男性行为者中的URAI相关。性暴力史、与年轻伴侣发生性行为、有6个及以上性伴侣以及无保护的首次性行为与年长男男性行为者中的URAI相关。婚姻状况、有稳定伴侣以及仅报告与男性发生性行为在两组中均与URAI相关。尽管能获取避孕套和润滑剂，但预防措施可能未有效惠及男男性行为者。必须考虑针对不同年龄的干预方法，包括耻辱感、歧视和风险认知。
