2010-2011年男性流动人群艾滋病哨点监测分析

Data analysis on AIDS sentinel surveillance to male migrant population in China in 2010-2011

目的分析中国男性流动人群艾滋病相关高危行为特征,为艾滋病防治提供科学依据。方法收集2010-2011年国家级流动人群哨点的监测数据。流动人群哨点设在流入地,每个哨点的样本量约为400人。在每年监测期内,采用统一设计的调查问卷,对男性流动人群进行问卷调查,并采集血液标本检测艾滋病病毒(HIV)。结果 2010年及2011年全国31个省87个流动人群哨点全部运行,纳入分析的哨点86个,分别监测男性流动人员31 620人和33 943人;艾滋病知识知晓率分别为74.1%和78.6%;自报最近1年发生商业性性行为的比例分别为12.7%和14.7%,最近1年与临时性伴发生性行为的比例分别为9.3%和10.3%。Logistic回归结果显示,高危性行为与年龄、婚姻状况、在本地居住时间等有关。结论需采取有效的干预措施减少该人群的HIV新发感染,控制艾滋病流行。
