目的：探讨男男性行为者(MSM)的性行为和危险行为的差异。方法：在横断面调查中，对18~岁的男同性恋者和双性恋者进行电话访谈，了解他们的性行为、HIV血清状态和男同性恋者的场所访问方式。结果显示，经常参观同性恋场馆的人更有可能从事高危性行为。在去过不同类型同性恋场所的同性恋场所中，去过5个或5个以上男性性伴侣和与第二性伴侣发生无保护肛交的男性最高(分别为62.6%和34.6%)，参加同性恋酒吧/俱乐部和游船的男性与女性发生性行为的比例较高(分别为8.5%和14.8%)，参加巡回派对的人群报告的HIV感染率(40.4%)和性行为不一致(30.2%)最高。结论：去过不同类型同性恋场所和不同走访频率的MSM在性行为危险行为方面存在显著差异，这些差异表明，在以场地为基础的研究中，加权程序对于获得公正的估计是重要的。
Objective: The objective of this study was to investigate differences in HIV prevalence and sexual risk behaviors among men who have sex with men (MSM) according to their gay venue visit patterns.Methods: In a cross-sectional survey, a population-based sample of men aged 18 to 64 years who self-identified as gay or bisexual were interviewed by telephone regarding their sexual behaviors, HIV serostatus, and gay venue visit patterns.Results: A total of 398 men were recruited for the study. The results showed that frequent gay venue visitors were more likely to engage in high-risk sexual behaviors. Among gay venue attendees who visited different types of gay venues, men who visited sex clubs/bathhouses reported the highest rates of 5 or more male sexual partners and unprotected anal intercourse (UAI) with secondary partners (62.6% and 34.6%, respectively), gay bar/club attendees and cruisers reported higher rates of having sex with women (8.5% and 14.8%, respectively), and circuit party attendees reported the highest HIV prevalence (40.4%) and serodiscordant UAI (30.2%).Conclusions: MSM who visited different types of gay venues and with varied visit frequency showed marked differences in sexual risk behaviors, and the differences suggest the importance of weighting procedure to obtain unbiased estimates in venue-based studies.
