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.
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.
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%).
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.
本研究旨在根据男男性行为者（MSM）光顾同性恋场所的模式，调查其艾滋病毒感染率和性风险行为的差异。
在一项横断面调查中，通过电话采访了18至64岁、自我认定为同性恋或双性恋的男性人群样本，询问他们的性行为、艾滋病毒血清学状态以及光顾同性恋场所的模式。
共招募了398名男性参与研究。结果显示，频繁光顾同性恋场所的人更有可能从事高风险性行为。在光顾不同类型同性恋场所的人群中，光顾性俱乐部/澡堂的男性报告有5个或更多男性性伴侣以及与次要性伴侣发生无保护肛交（UAI）的比例最高（分别为62.6%和34.6%），光顾同性恋酒吧/俱乐部的人和巡游者报告与女性发生性行为的比例较高（分别为8.5%和14.8%），参加巡回派对的人报告的艾滋病毒感染率最高（40.4%）以及血清学不一致的无保护肛交比例最高（30.2%）。
光顾不同类型同性恋场所且光顾频率各异的男男性行为者在性风险行为方面存在显著差异，这些差异表明在基于场所的研究中采用加权程序以获得无偏估计的重要性。
