Abstract:

目的了解浙江省台州市男男性行为者(MSM)艾滋病病毒/性传播感染(HIV/STI)及相关危险行为,初步了解其性关系网络.方法采用横断面研究设计,在台州市区2个MSM聚集地点以方便抽样法招募研究对象,知情同意后进行问卷调查,并采集血样检测HIV/STI感染. 结果共调查106名MSM,收获有效问卷97份;25.0%(23/92)的对象有过1名女性性伴,47.8%(44/92)有过≥2名女性性伴;14.3%(13/91)有过1名男性肛交性伴,80.2%(73/91)有过≥2名肛交性伴;22.1%(19/86)有过群交行为,62.5%(55/88)肛交时没有100%使用安全套;15.1%(14/93)有过1名男性口交性伴,75.3%(70/93)有≥2名男性口交性伴;38.9%(37/95)曾向女性买过性;35.5%(33/93)曾向男性买过性,15.3%(13/85)曾向男性卖过性.HIV抗体阳性率为3.9%(3/77),梅毒抗体阳性率为24.7%(18/73),Ⅱ-型单纯疱疹病毒抗体阳性率为15.1%(11/73),HCV抗体检测均为阴性.46名对象报告MSM认识关系个体中心网络,平均联结度数5.91,平均网络密度0.548;43名对象报告性关系个体中心网络,平均联结度数2.70,平均网络密度0.246. 结论台州地区MSM人群中存在多性伴、安全套使用率低、商业性服务等危险行为,HIV/STI感染率较高.MSM群体内部性关系紧密,可能存在一些高风险的疏离个体,仍需进一步研究其性关系网络与HIV/STI传播间的关系.
