目的研究不同场所男性双向性性行为者性行为特征。方法选择男男性行为者(men who have sex with men,MSM)聚集的浴池、酒吧、公园、会所为目标场所,采用分层整群抽样方法,抽取473名兼有异性性行为的MSM开展匿名问卷调查,同时进行艾滋病和梅毒血清学检测。对社区志愿者组织(CBO)关键人物及场所业主开展深度访谈。结果 473名MSM中,"1"(扮演"丈夫"者)占38.56%,"0.5"(可扮演"丈夫"或"妻子"者)占45.53%,"0"(扮演"妻子"者)占15.90%,酒吧和会所中"0"和"1"占比较大,浴池和公园中"1"占比较大;最近半年与女性发生过性行为的共占37.58%,公园和浴池中的占比高于酒吧和会所;有"滥交"经历的共占66.23%,按占比高低排序为:浴池、公园、会所、酒吧;每次性行为时均使用安全套的共占37.93%,活动于公园的最低;HIV抗体和梅毒血清学检测阳性率分别为4.44%和20.93%,浴池和公园的MSM感染率均较高。结论在针对MSM的艾滋病行为干预工作中,应将浴池和公园作为场所干预的重点。
