To understand the factors associated with the practice of chemsex among MSM in Brazil, especially during the Mpox health crisis, and to design effective prevention and intervention strategies specifically for this population.
A cross-sectional and analytical study using an electronic survey, conducted from September to December 2022, during the peak of the Mpox outbreak in Brazil.
A total of 1452 MSM aged 18 and older.
Data were collected via the REDCap platform through a survey with 46 questions. These addressed demographic data, sexual affiliations, practices, experiences with Mpox, healthcare service usage, and stigma or fear related to Mpox.
The prevalence of chemsex was 19.42% (n = 282). Multivariate Poisson modeling indicated a high incidence of chemsex among those diagnosed with Mpox and those involved in high-risk behaviors. The practice of chemsex was six times higher among those diagnosed with Mpox (95% CI: 4.73-9.10). MSM who engage in bugchasing had a prevalence twice that of the main outcome (95% CI: 1.31-3.16).
There is a significant need for targeted interventions for MSM in Brazil, especially given the Mpox outbreak. This study highlights the strong relationships between chemsex, experiences with Mpox, and various sexual behaviors, underscoring the importance of effective public health initiatives.
了解巴西男男性行为者中与化学性行为相关的因素，尤其是在猴痘健康危机期间，并专门为该人群设计有效的预防和干预策略。
一项横断面分析研究，采用电子调查问卷，于2022年9月至12月巴西猴痘疫情高峰期进行。
共有1452名18岁及以上的男男性行为者。
通过REDCap平台进行一项包含46个问题的调查收集数据。这些问题涉及人口统计学数据、性取向、行为、猴痘经历、医疗服务使用情况以及与猴痘相关的耻辱感或恐惧。
化学性行为的患病率为19.42%（n = 282）。多变量泊松模型表明，在被诊断患有猴痘的人群和参与高风险行为的人群中，化学性行为的发生率较高。被诊断患有猴痘的人群中化学性行为的发生率是普通人群的六倍（95%置信区间：4.73 - 9.10）。进行“猎阳”行为的男男性行为者的患病率是主要结果的两倍（95%置信区间：1.31 - 3.16）。
巴西对男男性行为者进行有针对性干预的需求非常迫切，尤其是考虑到猴痘疫情。本研究强调了化学性行为、猴痘经历和各种性行为之间的紧密关系，凸显了有效公共卫生举措的重要性。
