The practice of sex with casual partners without the use of adequate prevention in the period of social distancing due to the COVID-19 pandemic among men who have sex with men (MSM) can expose them to the risk of infection by the HIV virus. To assess this, we conducted an online survey in April and May 2020 in the entire national territory of Brazil and Portugal. We used the snowball technique for sampling, associated with circulation in social networks, totaling 2934 participants. Bivariate and multivariate logistic regression was used to produce the adjusted Odds Ratio (aOR). Eight-hundred-and-forty-two (28.7%) MSM presented at-risk sexual exposure in this period. In general, the types of sexual practices that most increased the chances of sexual exposure were having multiple partners (aOR:14.045); having practiced chemsex (aOR:2.246) and group sex (aOR:2.431), as well as presenting a history of at-risk sexual exposure (aOR:5.136). When we consider each country separately, the chances are increased in Brazil since the probability of the outcome was increased in those who practiced group sex (aOR:5.928), had multiple partners (aOR:19.132), and reported a sexual history of at-risk exposure (aOR:8.861). Our findings indicate that practices that are classically associated with greater chances of engaging in risky sexual exposure to HIV infection were the factors that most increased the chances of acquiring the virus in the pandemic context.
在 COVID-19 大流行期间，男男性行为者（MSM）与随意性伴侣发生性行为而不使用适当预防措施的做法，可能使他们面临感染艾滋病毒的风险。为了评估这一点，我们于 2020 年 4 月至 5 月在巴西和葡萄牙全国范围内进行了一项在线调查。我们采用滚雪球抽样技术，结合社交网络的传播，共有 2934 名参与者。我们使用二变量和多变量逻辑回归来生成调整后的优势比（aOR）。在这段时间内，842 名（28.7%）MSM 存在高危性行为暴露。总的来说，增加性行为暴露几率的性实践类型主要包括：有多个性伴侣（aOR：14.045）；有过化学性行为（aOR：2.246）和群交（aOR：2.431），以及有过高危性行为暴露史（aOR：5.136）。当我们分别考虑每个国家时，巴西的风险增加，因为发生结局的概率在那些进行群交（aOR：5.928）、有多个性伴侣（aOR：19.132）和有高危性行为暴露史（aOR：8.861）的人身上增加。我们的研究结果表明，与艾滋病毒感染的高风险性行为暴露相关的经典做法是在大流行背景下增加感染病毒几率的因素。
