目的建立对建筑行业农民工共用剃刀的干预模式并评估其效果。方法把591名农民工随机分成干预组与对照组,以个体干预为主对干预组进行干预并对效果进行评价。结果农民工干预前后行为与认识有显著变化,干预后61.38%干预组和22.26%对照组的农民工开始在理发店拒绝使用共用剃刀(OR=3.647;95%CI=2.242,5.934);干预组对有关疾病的概念、传播途径及预防知识的认识提高程度超过对照组。结论该行为干预模式在短期内能有效的促使农民工改变共用剃刀的习惯,长期效果有待于进一步研究。
Objective To establish an intervention model for sharing razors with migrant workers in the construction industry and evaluate their effects. Methods 591 migrant workers were randomly divided into intervention group and control group. Individual intervention was used to intervene the intervention group and the effect was evaluated. Results There were significant changes in behavior and cognition before and after intervention among migrant workers. After the intervention, migrant workers in 61.38% intervention group and 22.26% control group refused to use common razor in barber shop (OR = 3.647; 95% CI = 2.242, 5.934) The awareness of the concept, route of transmission and prevention knowledge about the disease increased more than the control group. Conclusion This behavioral intervention model can effectively encourage migrant workers to change the habit of sharing razors in the short term. The long-term effect needs further study.
