We investigated the extent to which Brazilian and Portuguese Men Who Have Sex with Men (MSM) had casual sex partners outside their homes during the period of sheltering in place for the COVID-19 pandemic.
An online survey was conducted in Brazil and Portugal in April, during the period of social isolation for COVID-19, with a sample of 2361 MSMs. Recruitment was done through meeting apps and Facebook.
Most of the sample (53.0%) had casual sex partners during sheltering. Factors that increased the odds of engaging in casual sex in Brazil were having group sex (aOR 2.1, 95% CI 1.3-3.4), living in an urban area (aOR 1.6, 95% CI 1.1-2.2), feeling that sheltering had a high impact on daily life (aOR 3.0, 95% CI 1.1-8.3), having casual instead of steady partners (aOR 2.5, 95% CI 1.8-3.5), and not decreasing the number of partners (aOR 6.5, 95% CI 4.2-10.0). In Portugal, the odds of engaging in casual sex increased with using Facebook to find partners (aOR 4.6, 95% CI 3.0-7.2), not decreasing the number of partners (aOR 3.8, 95% CI 2.9-5.9), usually finding partners in physical venues (pre-COVID-19) (aOR 5.4, 95% CI 3.2-8.9), feeling that the isolation had a high impact on daily life (aOR 3.0, 95% CI 1.3-6.7), and HIV-positive serostatus (aOR 11.7, 95% CI 4.7-29.2). Taking PrEP/Truvada to prevent COVID-19 was reported by 12.7% of MSM.
The pandemic has not stopped most of our MSM sample from finding sexual partners, with high-risk sexual behaviors continuing.
本研究旨在调查在 COVID-19 大流行期间，巴西和葡萄牙男男性行为者（MSM）在家中以外地区与偶然发生性行为的性伴侣的接触程度。
在 2020 年 4 月，即 COVID-19 社交隔离期间，通过巴西和葡萄牙的在线调查对 2361 名 MSM 进行抽样调查。招募工作是通过约会应用程序和 Facebook 进行的。
样本中大多数人（53.0%）在隔离期间有偶然发生性行为的性伴侣。增加巴西 MSM 发生偶然性行为的可能性的因素包括：发生群交（aOR 2.1，95%CI 1.3-3.4）、居住在城市地区（aOR 1.6，95%CI 1.1-2.2）、认为隔离对日常生活影响较大（aOR 3.0，95%CI 1.1-8.3）、拥有偶然而非稳定的性伴侣（aOR 2.5，95%CI 1.8-3.5）以及未减少性伴侣数量（aOR 6.5，95%CI 4.2-10.0）。在葡萄牙，增加发生偶然性行为的可能性的因素包括：使用 Facebook 寻找性伴侣（aOR 4.6，95%CI 3.0-7.2）、未减少性伴侣数量（aOR 3.8，95%CI 2.9-5.9）、通常在实体场所（新冠疫情前）寻找性伴侣（aOR 5.4，95%CI 3.2-8.9）、认为隔离对日常生活影响较大（aOR 3.0，95%CI 1.3-6.7）和 HIV 阳性血清学状态（aOR 11.7，95%CI 4.7-29.2）。有 12.7%的 MSM 报告为预防 COVID-19 而服用 PrEP/Truvada。
大流行并没有阻止我们的 MSM 样本中的大多数人寻找性伴侣，高危性行为仍在继续。
