【摘要】 目的了解青年学生中男男性行为人群(men who have sex with men,MSM)HIV、梅毒感染率及估计HIV发病率趋势状况。方法分析2006-2009年青年学生中男男性行为人群调查资料,比较分析HIV、梅毒感染率以及估计的HIV发病率的趋势。估计HIV发病率=HIV阳性数/[(年龄-与男性发生首次性行为的年龄)之和]。结果 2006-2009年分别调查了青年学生MSM人群210、206、181人和190人,最近1次与男性肛交时安全套使用率由2006年的48.0%上升至2009年的64.3%,最近6个月与男性发生无保护性肛交的比例由2006年的71.1%下降至2009年的65.3%。2006-2009年HIV感染率为4.3%、3.9%、11.0%、11.1%,梅毒感染率为7.1%、3.9%、2.8%、5.8%,对22岁及以下年龄组的估计发病率为1.4%、0.9%、2.4%和2.5%。结论重庆市MSM人群中青年学生HIV感染率高并呈上升的趋势,估计发病率也呈上升的趋势,流行形势严峻,急需针对该人群开展艾滋病防治工作。更多还原
