目的了解建筑工地农民工的艾滋病知识-态度-行为以及综合性干预措施的效果。方法利用分层整群抽样抽取了8个工地的646名农民工,进行现场流动式教育、同伴教育、免费发放安全套和建立免费的艾滋病宣传点与咨询中心等综合性干预措施。结果通过对比干预前646名和干预后573名农民工的艾滋病知识、态度和行为,综合性干预措施使农民工的艾滋病知识得分从11.41±6.57提高到15.10±6.02,传播途径知识错误率下降了10.29%～19.66%;对艾滋病病人的态度也发生了变化,不安全性行为中安全套经常使用率从52.27%提高到74.7%。结论该干预措施对建筑工地农民工预防和控制艾滋病方面具有较好的效果,值得在其他类似弱势人群中进行推广。
Objective To understand the knowledge, attitudes and behaviors of migrant workers in construction sites and the effects of comprehensive interventions. Methods A total of 646 migrant workers from 8 sites were sampled by stratified cluster sampling, and were provided with on-the-spot mobile education, peer education, free condom distribution, and free AIDS awareness and counseling centers. Results By comparing the knowledge, attitude and behavior of AIDS among 646 pre-interventions and 573 migrant workers after intervention, comprehensive interventions increased migrant workers’ AIDS knowledge score from 11.41 ± 6.57 to 15.10 ± 6.02, and the knowledge-based error rate of transmission route decreased by 10.29 % ~ 19.66%. The attitudes toward AIDS patients also changed. The frequent use of condoms in unsafe sex behaviors increased from 52.27% to 74.7%. Conclusion This intervention has good effect on prevention and control of AIDS among migrant workers in construction sites and should be promoted among other vulnerable groups.
