Compared with men who have sex with men only (MSMO), men who have sex with men and women (MSMW) consistently report higher rates of two HIV risk behaviors: transactional sex (TS) and concurrent substance use and sex (CSS). Within MSMW, little is known about how synergistic epidemics ("syndemics") affect TS and CSS. Using a sample of substance-using MSM (n = 515) in South Florida, we compared TS and CSS among MSMO and MSMW; examined whether, within MSMW (n = 86), TS and CSS predict unprotected anal intercourse with partners of serodiscordant/unknown HIV status (SU-UAI); and tested whether syndemics predict TS and CSS. MSMW reported higher rates of engaging in both TS and CSS (AOR = 1.7; 95 % CI 1.0-3.0). Within MSMW, engagement in both TS and CSS predicted SU-UAI (AOR = 3.3; 95 % CI 1.2-9.6); and syndemics predicted TS and CSS involvement (p < 0.01). Substance-using MSMW may benefit from interventions targeting TS, CSS, and background syndemics.
与仅与男性发生性行为的男性（MSMO）相比，与男性和女性都发生性行为的男性（MSMW）一直报告两种艾滋病毒风险行为的发生率较高：交易性行为（TS）以及同时使用毒品和发生性行为（CSS）。在MSMW群体中，对于协同流行（“综合征”）如何影响TS和CSS知之甚少。我们以南佛罗里达州使用毒品的男男性行为者（n = 515）为样本，比较了MSMO和MSMW之间的TS和CSS；研究了在MSMW群体（n = 86）中，TS和CSS是否能预测与血清学不一致/艾滋病毒状况未知的伴侣发生无保护肛交（SU-UAI）；并测试了综合征是否能预测TS和CSS。MSMW报告称参与TS和CSS的比例更高（调整后的比值比[AOR]=1.7；95%置信区间[CI]为1.0 - 3.0）。在MSMW群体中，参与TS和CSS可预测SU-UAI（AOR = 3.3；95% CI为1.2 - 9.6）；并且综合征可预测TS和CSS的参与情况（p < 0.01）。使用毒品的MSMW群体可能会从针对TS、CSS和背景综合征的干预措施中受益。
