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.

Objective To study the prevalence of human immunodeficiency virus(Hiv),sexually transmitted infection(Sti),risk behavior and the sexual neworks among men who have sex with men (MSM)in Taizhou city，Zhejiang province.Methods cross-sectional Astudy was applied with venue-based sampling in 2 MSM gathering sites in Taizhou.'Informed Consent'principle was applied and MSM were studied through a structured questionnaire．Blood samples were collected from thee who accepted free and confidential HIV/STI counseling and then tested for HIV,syphilis,HCV and HsV-2 antibodies with ELISA.HIV positive sera were certified with western blot．Results 106 MSM were investigated and 97 qualified questionnaires were collected.25.0％(23/92)of these MSM have ever had l female sex partner while 47.8％(44/92)had 2 or more.14.3％(13/91)of them reported having had 1 male partner who had engaged in anal sex and 80.2％(73/91)had 2 or more.22.1％(19／86)of therh had partieipated in group sex but 62.5％(55／88)of them did not always use condom when having analintercourse.15.1％(14／93) of them had l orfll sex partner while 75.3％(70／93)having 2 or more.38.9％(37／95)of them had sex with female sex worker,and 35.5％(33／93)had sex with male-to-male sex worker.15.3％(13/85)0f them had once been male-to-male sex worker themselves.3.9％(3/77)of them were found HIV positive in blood tests,with 24.7％(18/73)positive of syphilis,15.1％(11/73)positive ofHSV-2 but HCV appeared to be negative.46 csses reported their egocentric recognition networks,with mean degree of 5.91(ranging0-10),and mesa density of 0.548(ranging 0．000-1.000).43 sexual networks were identified,with mean degree of 2.70(ranging 0-10),and mean density of 0.246(ranging 0.000-1.000).Conclusion Risk behaviors,such as multiple sex partners，IOW proportion of condom use and commercial sex engagement both with heterosexuals and homosexuals,were extensively existed among MSM in Taizhou,and the prevalence of HIV/STI was relatively high.Their sexual networks seemed complicated but there might be in place of some sukstantiaUy isolated MSM groups with high risk of Hlv/sTl infection.More study should be applied to identify the relationship between scxual networks and HIV/STI transmigsion.
