外来务工人员艾滋病知识、行为和艾滋病病毒感染状况调查

目的了解外来务工人员艾滋病相关知识知晓状况、危险行为以及艾滋病病毒感染状况。方法采用分层随机抽样的方法，对东部沿海某市18-60岁外来务工人员进行问卷调查，收集艾滋病知识和行为的信息，并采集静脉血进行艾滋病病毒抗体检测。结果1190名调查对象对艾滋病的传播途径全部回答正确的占71．9％。对于非传播途径和预防措施全部回答正确的分别占18．2％和7．1％，所有问题均能正确回答的仅占2．5％。在有过性经历者中，非婚性行为者占41．7％，有过商业性行为者占11．4％。在与固定性伴和商业性性伴发生性行为时，最近一次性行为时使用安全套的比例分别为32．9％和46．7％。多因素分析显示，正确知晓传播途径与文化程度和有性经历有关。无论与固定性伴，还是商业性性伴，最近一次性行为使用安全套的均与正确知晓传播途径有关。1125名工人艾滋病病毒抗体检测结果均为阴性。结论针对外来务工人员艾滋病知识的薄弱环节，开展宣传教育。通过艾滋病知识知晓率的提高，促进高危行为的改变。同时需要加强对该人群的监测。
