目的了解北京市流动人口艾滋病知识知晓情况、行为特征、艾滋病/性病感染状况及影响因素。方法于2009年6—12月,对北京市外来建筑工人、企业员工和商贸经营人员进行匿名自填式问卷调查,采集血样检测艾滋病病毒(HIV)、梅毒及丙型肝炎病毒(HCV)。结果共调查4 187人,未检出HIV抗体阳性,梅毒检出率为0.4%(15/4 187),HCV检出率为0.6%(25/4 187);艾滋病知识知晓率为63.9%(2 677/4 187),75.9%(3 144/4 141)的调查对象有过性行为史,4.3%(177/4 141)最近1年有过非商业临时性行为,其中从未使用安全套者占27.1%(48/177),仅29.4%(52/177)每次均用;多因素logistic回归分析结果显示,年龄、婚姻状况、文化程度、在本地居住时间和职业类型是流动人口艾滋病知识知晓情况的影响因素;性别、婚姻状况和在本地居住时间是流动人口临时性行为发生的影响因素。结论北京市流动人口对艾滋病知识了解不够,且存在相当比例的非保护临时性行为,具有HIV传播流行的风险,应加强对其进行相关健康教育和行为干预。
