男男性行为人群艾滋病防治网络干预效果评价

目的评价利用网络平台对男男性行为人群(MSM)在艾滋病知识的认知、态度及行为学方面的干预效果。方法主要采用网络调查及网络干预的模式,对MSM人群进行艾滋病预防知识、态度、行为干预进行评价,包括两次横断面调查和为期2个月的3期网络干预。结果共调查1 293人,平均年龄为(27.6±6.0)岁,其中75%年龄在18～30岁之间;86.2%为专科或本科以上学历;64.8%目前居住在北京。干预前后,MSM人群艾滋病知识知晓情况、安全套使用及HIV检测情况等方面的差异有统计学意义(P<0.05)。但在减少过去6个月中的肛交行为、消除阻碍接受HIV检测的因素等方面,网络干预不具有显著效果(P>0.05)。结论针对MSM人群,可以尝试采用网络干预的方法来提高艾滋病防治知识,减少HIV感染的高危行为,促进接受HIV检测。
