Characteristic of sexual partner network and HIV transmission among men who have sex with men

摘要

摘要:
目的了解男男性接触者(MSM)性伴网络特征, 探讨人类免疫缺陷病毒/性传播疾病(HIV/STDs)从该人群向普通人群传播的途径, 为开展HIV/STDs的预防与控制提供依据。
方法以同性恋酒吧为研究现场, 以其中男男性接触者为对象进行匿名问卷调查。调查内容包括社会人口学特征、HIV/STDs感染状况、性伴类型及数量等。
结果某市酒吧中MSM的HIV和STDs感染报告率分别为3.4%和10.3%;多性伴现象在MSM中普遍存在, 且性伴类型广泛。在最近2个月中, 50.0%的MSM有同性偶然性伴, 17.8%有同性商业性伴, 63.8%目前有同性固定性伴。曾有过异性性伴者为55.7%。拥有3种类型性伴者为19.5%, 4种类型性伴者为12.6%。拥有不同类型性伴的MSM亚群之间相互关联, 核心亚群为拥有异性性伴和拥有同性商业性伴亚群。
结论 MSM以多维的性伴网络相互连接, 不仅在MSM人群内部具有HIV/STDs的多向传播通道, 而且已经形成了向普通人群传播的桥梁。
