Men who have sex with men and women (MSMW) are a potential bridge population for transmitting HIV to heterosexual women. This study assessed key characteristics of this subgroup of men who have sex with men (MSM) in China. Of 1141 eligible MSM, 45.6% reported bisexual behaviors. Besides marriage as a strong predictor (odds ratio: 23.90, 95% confidence interval: 14.29-39.98), older age (1.12, 1.10-1.15) and lower education (or no college education) (1.98, 1.52-2.59) were also independently associated with having ever had sex with women. MSMW reported higher proportions of alcohol drinking, heterosexual/bisexual orientation, and preference for an insertive role in anal sex than men who had sex with men only; but there was no statistically significant difference between two groups in prevalence of HIV and syphilis infections and in history of sexually transmitted infections. HIV prevention intervention programs should break the bridging role of HIV transmission in MSMW population.
男男性行为者和女性(MSMW)是将 HIV 传播给异性恋女性的潜在桥梁人群。本研究评估了中国男男性行为者(MSM)这一亚组的关键特征。在 1141 名符合条件的男男性行为者中,45.6%报告有双性性行为。除了婚姻是一个强有力的预测因素(优势比:23.90,95%置信区间:14.29-39.98)外,年龄较大(1.12,1.10-1.15)和教育程度较低(或没有大学教育)(1.98,1.52-2.59)也与曾经与女性发生过性行为独立相关。MSMW 报告了更高比例的饮酒、异性恋/双性恋倾向以及在肛交中更喜欢主动角色,而不仅仅是男男性行为者;但两组在 HIV 和梅毒感染的患病率以及性传播感染的历史方面没有统计学上的显著差异。艾滋病毒预防干预计划应打破 MSMW 人群中艾滋病毒传播的桥梁作用。
