目的研究建立男性农民工使用共用剃刀的重复干预模式,并评估干预效果。方法将423名男性农民工随机分成重复干预组、干预组和对照组。采用先填问卷后干预的模式,对3组人员进行不同程度的知识和行为干预,在45 d和90 d后回访,采用广义估计方程和χ2检验进行统计学分析。结果重复干预组、干预组和对照组收到的有效问卷分别为121、127和131份。比较前后2次回访结果,各组人员在理发店使用共用剃刀比例分别为:重复干预组30.6%和29.8%,干预组29.1%和44.1%,对照组46.6%和48.9%。重复干预组干预效果较另外2组有统计学意义。结论干预可减少研究对象使用共用剃刀,重复干预效果好于一般干预,更有利于促进男性农民工减少甚至拒绝使用共用剃刀。因此,重复干预模式的意义值得研究和探讨。
Objective To establish a repeated intervention model for male migrant workers using a common razor and to evaluate the intervention effect. Methods 423 male migrant workers were randomly divided into repeated intervention group, intervention group and control group. After questionnaire intervention, knowledge and behavior intervention were conducted on 3 groups of people at different levels. After 45 days and 90 days, interviews were conducted. Generalized estimation equation and χ2 test were used for statistical analysis. Results In the repeated intervention group, effective questionnaires received by the intervention group and the control group were 121, 127 and 131 respectively. Comparing the results of two visits before and after, the proportions of the common razors in the barbershop were 30.6% and 29.8% in the intervention group, 29.1% and 44.1% in the intervention group and 46.6% and 48.9% in the control group respectively. Intervention intervention group than the other two groups were statistically significant. Conclusion Intervention can reduce the use of shared razors, repeated interventions are better than general intervention, and more conducive to promoting male migrant workers to reduce or even refuse to use a common razor. Therefore, the significance of repeated intervention patterns deserves research and discussion.
