利用互联网对男男性行为人群进行艾滋病防治干预的可行性研究

目的了解互联网对男男性行为人群(MSM)艾滋病相关知识、行为及检测情况的影响,探索利用互联网进行MSM艾滋病防治干预的可行性。方法 2009年7-9月,采用同伴推动抽样方法共招募477名MSM进行面对面问卷调查,所得资料用SPSS软件进行数据分析和处理。结果网络为主型MSM和非网络为主型MSM在婚姻状况(χ2=8.696,P=0.027)、文化程度(χ2=8.303,P=0.016)、户籍(χ2=13.252,P=0.001)方面的分布差异有统计学意义;艾滋病防治知识知晓率,网络为主型为91.4%(318/348),非网络为主型为82.9%(102/123),网络为主型更高(χ2=6.724,P=0.010);最近六个月同性性伴数,网络为主型平均为(2.91±3.45)人,非网络为主型平均为(4.52±6.75)人,两组比较差异有统计学意义(t=-2.286,P=0.024,χ2=9.932,P=0.019);最近六个月与同性发生插入性行为坚持每次使用安全套的,网络为主型有34.9%(107/307),非网络为主型有33.0%(35/106)。结论互联网对MSM的艾滋病相关知识、行为有正面影响,应重视和加强利用互联网对MSM开展艾滋病防治干预工作。

Feasibility study on intervention for AIDS prevention and control among men who have sex with men with Internet

Objective To indentify the effect of Internet on AIDS related knowledge,behavior and testing in MSM,and to explore the feasibility of intervention for AIDS prevention and control among them with Internet.Methods A respondent-driven sampling was used to recruit 477 MSM for a face-to-face questionnaire survey between July and September in 2009.The data collected were processed and analyzed with SPSS.Results There were significant differences between Internet MSM and non-Internet MSM in marital status(χ2=8.696,P=0.027),education(χ2=8.303,P=0.016) and household register(χ2=13.252,P=0.001).The awareness rate of knowledge related to AIDS prevention and control among Internet MSM was higher than among non-Internet MSM(91.4% vs.82.9%,χ2=6.724,P=0.010).Non-Internet MSM had more homosexual sex partners than Internet MSM in the last six months(4.52±6.75vs.2.91±3.45,t=-2.286,P=0.024,χ2=9.932,P=0.019).The consistent condom-using rate with homosexual sex partners in the last six months among Internet MSM was 34.9% and that among non-Internet MSM was 33.0%.Conclusion Internet has positive impact on AIDS related knowledge and behavior in MSM.We should value and strengthen the use of Internet to implement AIDS prevention and control among MSM.
