Abstract

BackgroundThis study aimed to assess HIV prevalence and associated sexual behaviors among immigrant men who have sex with men (MSM) in Brazil and Portugal, recognizing the elevated vulnerability of this population due to sociocultural and structural barriers.MethodsA cross-sectional online survey was conducted between January 2020 and May 2021 with 2033 immigrant MSM. Participants were recruited using snowball sampling through dating applications. Data were self-reported and analyzed to identify associations between sexual behaviors and HIV status.ResultsThe overall HIV prevalence was 11.7%. Higher-risk sexual practices were frequent, including receptive anal intercourse and having multiple sexual partners. Conversely, low adoption of preventive behaviors such as sexual abstinence and non-penetrative sex was observed. Condomless sex was commonly justified by trust in partners or recent negative HIV test results. Factors independently associated with unprotected sex included being versatile or receptive in anal sex and not disclosing HIV status on dating apps. Gaps in HIV prevention knowledge and engagement were also identified.ConclusionsImmigrant MSM in Brazil and Portugal experience a high burden of HIV and engage in behaviors that increase their risk of infection. Cultural and structural barriers-such as language difficulties, limited healthcare access, and stigma-contribute to inadequate prevention practices. These findings highlight the urgent need for targeted, culturally competent public health interventions to expand access to HIV prevention strategies and reduce transmission risk in this underserved population.

巴西和葡萄牙男男性行为移民中HIV的流行及预防行为。
本研究旨在评估巴西和葡萄牙男男性行为移民(MSM)中HIV的流行情况和相关的性行为,认识到由于社会文化和结构障碍,这一人群的易感性增加。方法于2020年1月至2021年5月对2033名移民男男性行为者进行横断面在线调查。参与者是通过约会应用的滚雪球抽样方式招募的。数据是自我报告和分析,以确定性行为和艾滋病毒状况之间的联系。结果我市HIV总患病率为11.7%。高风险的性行为频繁,包括接受性肛交和拥有多个性伴侣。相反,预防性行为如性节制和非插入性行为的采纳率较低。对伴侣的信任或最近的艾滋病毒检测结果呈阴性通常证明无安全套性行为是合理的。与无保护的性行为独立相关的因素包括多面手或接受肛交,以及不在约会软件上透露自己的艾滋病毒状况。还确定了艾滋病毒预防知识和参与方面的差距。结论巴西和葡萄牙MSM移民的HIV感染负担较高,其行为增加了感染风险。文化和结构障碍——如语言障碍、有限的医疗保健机会和耻辱感——导致预防措施不充分。这些发现突出表明,迫切需要有针对性的、文化上有能力的公共卫生干预措施,以扩大获得艾滋病毒预防战略的机会,并减少这一服务不足人群的传播风险。
