计划生育优质服务综合干预对3个城市流动人口安全套使用的影响

目的：评估开展计划生育优质服务干预活动对上海、北京、成都三城市流动人口安全套使用的影响。方法采用多阶段整群抽样的方法，在北京、上海、成都三个中心选择流动人口集中的工厂、建筑工地和服务娱乐场所各4个，实际调查流动人口6304例。随机分为干预组（2974例）和对照组（3330例）。在选定的干预组实施计划生育优质服务综合干预方案，对照组开展常规工作。通过结构式问卷调查评估干预对安全套使用的效果。结果基线调查中有1130名流动人口使用安全套。干预后最近3次性生活均坚持使用安全套的比例上升。上海现场干预组从93.5％提高到95.9％；北京现场干预组从87.8％提高到95.5％；成都现场干预组从96.7％提高到97.8％。加权最小二乘估计模型结果提示，北京现场的干预能提高流动人口安全套坚持使用率。结论干预活动促进了流动人口安全套的使用，今后应将干预活动融入常规工作，提高安全套使用率。

Effect of quality service intervention on condom use among migrants in three cities

Objective Toexploretheeffectofinterventionmeasuresoncondomuseamongmigrantsinthree cities,including Beijing,Shanghai,and Chengdu. Methods In the three cities,four districts of each city were selected,using multi-stage cluster sampling,and the districts were randomly divided into intervention group and control group.Intervention measures were implemented in the intervention group, while routine family planning work was conducted in the control group.Then structured questioners were used to assess the effect. Results There were 1 130 migrant workers who used condom in the baseline survey.After the intervention,the proportion of condom usage increased from 93.50% to 95.93% in Shanghai,87.84% to 95.50% in Beijing,and 96.69% to 97.79% in Chengdu.Weighted least squares estimate model showed that intervention measures were associated with sustained condom use. Conclusion Intervention programmes can improve condom use in the floating population.
