| Abstract: |
| 目的用连续横断面调查和BED．捕获酶联试验(BED-cE认)估算重庆市男男性行为(MsM)人群中HIV-1的发病率及其变化趋势。方法利用“滚雪球”和“方便抽样”方法招募得到样本，用BED-CEIA进行HIV-1新近感染检测，并根据标准公式和2种校正公式估算该人群2006——2008年连续3年的发病率；比较不同抽样场所和不同年龄组所得结果，进行发病率的分层分析。结果2006-2008年调查人数分别为1000、1044和945，HIV-1年感染发病率分别为7．01％、7．98％和7．80％。不同采样场所的HIV-1感染发病率差异有统计学意义，2007年和2008年MSM发病率最高的人群分别来自浴室和通过网络寻找性伴的MSM，分别达到17．87％和12．22％；2008年2l～25岁年龄组HIV-1发病率最高，达8．69％；不同方法的校正降低了对发病率的估计。结论重庆市MSM人群HIV-I新发感染维持在较高水平，但连续3年的发病率经校正后上升趋势不明显。 |
