甘肃省2006-2011年监管场所羁押人员艾滋病感染状况调查

目的及时掌握甘肃省看守所、强制戒毒所、收容教育所和监狱、劳教所等监管场所被监管人员艾滋病病毒（HIV）的感染状况,为制定艾滋病防治政策和措施提供依据。方法对2006-2011年监管场所新入人员进行行为学监测和HIV抗体筛查,运用流行病学调查方法对收集的资料进行整理和统计分析。结果共105 978人进行HIV抗体筛查,发现HIV抗体阳性84人,阳性率0.08%,感染者中静脉注射吸毒人群和性乱人群占72.62%（61/84）,男性占86.90%（73/84）,20~39岁年龄段人员占80.95%（68/84）,户籍所在地为外省者占57.14%（48/84）;连续6年监测发现HIV抗体阳性人数没有明显增减的趋势;女性高危行为发生率为0.04%,HIV抗体阳性率为0.21%。结论静脉注射吸毒和性乱是甘肃省监管场所羁押人员HIV传播的主要危险因素,20~39岁年龄组是高危行为发生和HIV感染的主要群体,监管场所中女性应成为甘肃省艾滋病预防和干预的重点人群。
