目的通过对南宁市外来建筑工地民工艾滋病高危行为实施干预措施,了解建筑工地农民工干预前后其行为改变,探索有效的干预模式。方法通过分层整群随机抽样方法,采用对南宁市6个外来建筑工地农民工开展系列宣传干预、持续同伴教育等综合干预模式,在干预前后分别抽取264人和366人进行面对面匿名问卷调查,分析干预前后其高危行为改变情况。结果干预前商业性行为时使用安全套的人占33.3%,干预后,最近一次发生商业性行为时使用安全套的比例提高到71.4%(P<0.05),但与女性性工作者的性行为频率及与固定性伴使用安全套的比例和频率均没有显著性的改变(P>0.05)。结论建筑工地民工群体以青壮年为主,与家庭长期分离,且预防艾滋病技能较为缺乏,容易发生商业性行为等危险性行为,安全套使用率低,针对该人群特点实施形式多样的综合干预模式可在一定程度上减少危险性行为的发生。
