目的了解MSM人群的多性伴情况,分析其影响因素。方法采用“滚雪球”方法,对六安市城区MSM进行匿名问卷调查,收集MSM人群人口学和性伴数及影响因素等资料。使用Epi Data3.1软件建立数据库,运用SPSS18.0进行统计分析。结果 59.5%的调查对象有2个以上男性肛交性伴,单因素分析显示:HIV风险感知(χ2=4.946,P=0.026)是影响因素。Logistic回归分析结果显示:HIV风险感知(OR=2.091,95%CI=1.084~4.035)是独立影响因素;56.3%的调查对象有2个以上男性口交性伴,单因素分析显示:年龄(χ2=3.456,P=0.036)、知晓艾滋病相关知识(χ2=4.52,P=0.034)及是否有女性性伴(χ2=8.071,P=0.04)是影响因素。Logistic回归分析结果显示:有女性性伴(OR=0.278,95%CI=0.11~0.702)是独立影响因素。结论目前开展的干预服务对该人群的多性伴行为无明显影响,可以尝试从HIV风险感知角度进行有针对性干预,以降低其艾滋病感染风险。
Objective To understand the status of multiple sexual partners in MSM population and analyze its influential factors. Methods The “snowball” method was used to conduct an anonymous questionnaire survey on MSM in urban areas of Lu’an and to collect demographic information, sex partners and influencing factors of MSM population. The use of Epi Data3.1 software to establish a database using SPSS18.0 statistical analysis. Results 59.5% of the respondents had more than 2 male anal sex partners. Univariate analysis showed that HIV risk perception (χ2 = 4.946, P = 0.026) was the influencing factor. Logistic regression analysis showed that HIV risk perception (OR = 2.091, 95% CI = 1.084-4.035) was an independent influencing factor; 56.3% of the respondents had more than 2 male oral sex partners and univariate analysis showed that age (χ2 = 3.456, P = 0.036). Knowledge of AIDS (χ2 = 4.52, P = 0.034) and female sexual partners (χ2 = 8.071, P = 0.04) were the influencing factors. Logistic regression analysis showed that female partners (OR = 0.278, 95% CI = 0.11-0.702) were independent influencing factors. Conclusions The current intervention service has no obvious effect on the multi-sex partner’s behavior in this population. We can try targeted intervention from the perspective of HIV risk perception to reduce the risk of HIV infection.
