| 目的 了解中国男男性行为兼异性性行为者(MSMW)的HIV感染状况及其与男性和女性的性行为特征.方法 采用“滚雪球”方法在广州和成都市各招募300名MSMW为研究对象,进行问卷调查(社会人口学特征、最近6个月男性性伴种类和特征、男男性行为及安全套使用状况、最近12个月异性性伴种类和特征、异性性行为及安全套使用状况)和HIV抗体检测.结果 共600名MSMW接受问卷调查和HIV检测,HIV感染率和检出率分别为26.2％和8.5％；最近6个月有28.0％的调查对象拥有≥5名男性性伴,肛交行为时每次使用安全套者占44.2％,最近3次和最近1次男男肛交性行为使用安全套者分别为52.3％和63.0％；最近12个月有86.0％的调查对象与女性发生性行为,其中配偶、婚前女友、婚外情人、女性偶然性伴和女性商业性伴的比例分别为65.0％、27.2％、1.5％、12.7％和4.5％,约1/3的调查对象异性性行为时坚持每次使用安全套,36.5％在最近3次异性性行为时均不使用安全套.最近6、12个月成都市MSMW男男性行为时每次使用安全套分别为55.7％和38.3％,均高于广州市(32.7％和25.3％).HIV阳性者中,与男性发生肛交性行为者为91.1％,最近6个月与男性发生肛交行为时每次使用安全套者为49.7％,最近3次和最近1次男男肛交性行为使用安全套者分别为60.5％和69.4％；最近12个月有82.8％阳性调查者与异性发生过性行为,42.0％每次性行为坚持使用安全套,最近3次性行为使用安全套者占47.8％.最近6、12个月,既往检测HIV阳性MSMW从不使用安全套同性和异性性行为的比例(分别为4.3％和12.9％)均低于本次检测HIV阳性MSMW(22.0％和46.3％).结论 MSMW人群的HIV感染率已经处于较高水平,并存在较高比例的无保护男性肛交性行为和女性阴道性交行为,该人群在HIV跨性别传播中的桥梁作用可能加快HIV在普通人群中的蔓延. |
