Abstract

Background

Men who have sex with men (MSM) are a significant population contributing to human immunodeficiency virus (HIV) transmission. Nevertheless, few studies have focused on the heterogeneity in MSM. The characteristics of men who have sex with men and women (MSMW) may differ from men who have sex with men only (MSMO).

Methods

From October 2022 to March 2023, a cross-sectional study for MSM was conducted in Eastern China. An electronic questionnaire was used to collect the demographic characteristics and sexual behaviors of participants. A multivariable logistic regression model was used to assess the differences in HIV-related risky sexual behaviors between MSMO and MSMW.

Results

A total of 1993 MSM were enrolled in the study, with 1221 MSMO and 772 MSMW. Compared to MSMW, MSMO reported younger age at first anal sex, higher coerced homosexual experiences, and observed different characteristics of sexual behavior in the past six months. Multivariable analysis indicated that MSMW were more likely to seek casual partners and use stimulants online and offline. MSMW showed inconsistent condom use with online partners (aOR = 0.51, 95 %CI: 0.38–0.68) and more frequent anal sex after drinking (aOR = 2.27, 95 %CI: 1.54–3.35). They also had higher risks of commercial (aOR = 2.47, 95 %CI: 1.71–3.57) and group sexual behaviors (aOR = 1.88, 95 %CI: 1.24–2.83) compared to MSMO.

Conclusion

Our findings suggest that the differential factors may lead MSMW to become a subgroup at high risk of HIV infection. The gender identity and sexual orientation within MSM should be considered when formulating acquired immune deficiency syndrome (AIDS) prevention and control strategies.

仅与男性发生性关系的男性和与男性和女性发生性关系的男性之间与人类免疫缺陷病毒有关的危险性行为的比较：华东地区横断面研究

背景男男性行为者（MSM）是导致人类免疫缺陷病毒（HIV）传播的重要人群。然而，很少有研究关注 MSM 的异质性。方法从 2022 年 10 月至 2023 年 3 月，在华东地区开展了一项针对 MSM 的横断面研究。研究使用电子问卷收集参与者的人口统计学特征和性行为。研究采用多变量逻辑回归模型来评估 MSMO 和 MSMW 之间与 HIV 相关的危险性行为的差异。结果共有 1993 名 MSM 参与研究，其中 MSMO 1221 人，MSMW 772 人。与男男性行为者相比，男男性行为者报告的首次肛交年龄更小、被胁迫的同性性行为经历更多，并且在过去 6 个月中观察到不同的性行为特征。多变量分析表明，男男性行为者更有可能在网上和网下寻找临时性伴侣和使用兴奋剂。男性同性恋、双性恋和变性者与在线伴侣的安全套使用不一致（aOR = 0.51，95 %CI：0.38-0.68），酒后肛交更频繁（aOR = 2.27，95 %CI：1.54-3.35）。与 MSMO 相比，他们的商业性行为（aOR = 2.47，95 %CI：1.71-3.57）和集体性行为（aOR = 1.88，95 %CI：1.24-2.83）的风险也更高。在制定获得性免疫缺陷综合征（艾滋病）预防和控制策略时，应考虑 MSM 的性别认同和性取向。
