摘　　要：目的了解艾滋病病毒(HIV)感染者推介(社交网络中)的青年学生男男性行为者(MSM)多性伴侣与安全套使用情况。方法在哈尔滨、天津、西安、重庆与疾病预防控制中心合作,通过滚雪球抽样和受试者推荐的混合抽样方法,在HIV感染的青年学生社交圈中的MSM进行横断面调查,收集一般人口学特征、高危性行为发生情况。结果共收集有效问卷549份,平均年龄为(21.33±2.35)岁,其中182例(33.2%)为HIV感染者;有40.6%(206/508)最近3个月或确诊前3个月未持续使用安全套,51.1%(270/528)最近3个月或确诊前3个月有超过两个以上的性伴,25.2%(128/508)最近3个月或确诊前3个月既多性伴又未持续使用安全套。调查发现,青年学生有1~3个固定男性性伴[1个:调整比值比(aOR)=2.37,95%可信区间(CI):1.55~3.64;2~3个:aOR=2.17,95%CI:1.30~3.64]或1~3个临时男性性伴(1个:aOR=1.86,95%CI:1.18~2.94;2~3个:aOR=2.20,95%CI:1.38~3.50)时,不持续使用安全套的概率大大增加。有1个以上的商业男性性伴(aOR=3.34,95%CI:1.14~9.79),或1个以上的固定女性性伴(aOR=2.65,95%CI:1.26~5.59),或1个以上的临时女性性伴(aOR=3.07,95%CI:1.13~8.35)的青年学生也会不持续使用安全套。结论 HIV感染青年学生社交圈中的学生MSM多性伴和不持续使用安全套现象普遍,且性伴的类型和数量与安全套的使用之间存在相关,需要针对性地根据其行为特征进行艾滋病干预工作。Objective To understand the situation of multiple sex partners and condom use among men who have sex with men(MSM)in the HIV-infected students’ social network.Methods A mixed recruitment method of snowball sampling and respondent-driven sampling was used to recruit HIV-infected students with the help of local CDC in Harbin,Tianjin,Xi’an and Chongqing,and information was collected on the demographic characteristics,sexual behaviors and psychosocial characteristics among the eligible participants via a self-administrated questionnaire.Results A total of 549 valid questionnaires were collected.The average age of students was 21.33±2.35.Among them,182(33.2%)were HIV-positive and 367(66.8%)were HIV-negative.40.6%(206/508)students did not use condom consistently.51.1%(270/528)had more than two sex partners;25.2%(128/508)students reported having multiple sex partners and having unprotected sexual behavior concurrently.In this survey,students with more than 1 or 3 regular male sex partners or casual male sex partners were less likely to use condoms consistently.However,as for those who had≥4 male sex partners,the association between condom use and multiple sex partners was not statistically significant.The students who had 1-3 regular male sex partners(1:aOR=2.37,95%CI:1.55-3.64;2-3:aOR=2.17,95% CI:1.30-3.64)or 1-3 causal male sex partners(1:aOR=1.86,95%CI:1.18-2.94;2-3:aOR=2.20,95%CI:1.38-3.50)were less likely use condoms consistently.Those who had more than one commercial male sex partner(aOR=3.34,95% CI:1.14-9.79),or more than one regular female sex partner(aOR=2.65,95% CI:1.26-5.59),or more than one casual female sex partner(aOR=3.07,95% CI:1.13-8.35),the risk of non-condom use was also high.Conclusion The MSM sexual partners and non-consistent condom use are common in the social circle of students infected with HIV.So it is necessary to carry out tailored HIV intervention according to the characteristics of this key risk group.
