目的:分析干预项目对流动人口宫内节育器(IUD)使用和认知的影响,为进一步开展避孕节育促进项目提供参考。方法:采用多阶段整群抽样的方法抽取18~49岁流动人口(6 304人),分为干预组(3 330人)和对照组(2 974人)。对照组开展常规计划生育服务,干预组实施包括倡导、动员、管理、培训等在内的一系列干预活动。分析干预项目对研究对象IUD使用和认知的影响,采用卡方检验、加权最小二乘估计模型等方法进行统计分析。结果:干预后,在基线调查和评估调查中都使用IUD的1 688名研究对象中,对照组调查不知道所用IUD种类的比例由58.28%下降为43.77%;干预组基线调查不知道所用IUD种类的比例由66.56%下降为18.59%,2组组别和时间的交互作用项差异有统计学意义。结论:干预能提高流动人口对所用IUD种类的认识,进一步广泛推广针对流动人口的避孕节育干预项目具有重要的现实意义。
OBJECTIVE: To analyze the impact of intervention programs on the use and cognition of intrauterine devices (IUDs) for floating population and provide reference for further promoting contraceptive programs. Methods: A multistage cluster sampling method was used to collect floating population aged 18-49 (6,304), divided into intervention group (3 330) and control group (2 974). Control group to carry out regular family planning services, the intervention group to implement, including advocacy, mobilization, management, training, etc., a series of interventions. The impact of the intervention program on the use and cognition of IUD was analyzed. The data were analyzed by chi-square test and weighted least-squares estimation model. RESULTS: Of the 1 688 subjects who used IUD in their baseline and assessment surveys after intervention, the percentage of IUDs in the control group who did not know the type of IUD used fell from 58.28% to 43.77%; the intervention group did not know the type of IUD used Decreased from 66.56% to 18.59%, there was significant difference in the interaction between two groups and time. Conclusion: Intervention can improve the floating population’s understanding of the type of IUD used, and further promote the contraceptive intervention program for floating population is of great practical significance.
