[目的]通过对上海市闵行区流动人口避孕节育干预项目对研究对象宫内节育器(IUD)和安全套使用的影响分析,评估干预措施的效果。[方法]多阶段整群抽取上海市闵行区流动人口集中的工厂、建筑工地、服务娱乐场所,随机分干预组和对照组。通过倡导、动员,管理,培训,宣传教育,咨询服务,技术服务,随访服务,转诊机制等干预活动对研究对象进行干预。应用卡方检验及有序多分类Logistic回归分析等方法对其影响进行分析。[结果]本研究基线共调查2001人,评估调查时随访到有效样本1791人(失访率10.49%)。研究期间,干预组对象的查环率、避孕套的坚持使用的比例均显著高于对照组。查环率的多因素Logistic回归分析显示干预活动的调整OR为4.280,95%可信区间为2.912～6.291;最近3次性生活是否均使用避孕套的多因素分析显示干预活动的OR为2.483,95%可信区间为1.226～5.028。[结论]干预项目取得一定成效,促进了流动人口宫内节育器的检查和安全套的正确使用。
[Objective] To evaluate the effect of intervention on IUD and condom use in floating population contraception in Minhang District of Shanghai. [Method] The multistage cluster was used to extract the factories, construction sites and entertainment venues with floating population in Minhang District, Shanghai. Randomly divided into intervention group and control group. Through interventions such as advocacy, mobilization, management, training, publicity and education, counseling services, technical services, follow-up services, referral mechanisms and other interventions, the participants were intervened. Applying chi-square test and ordinal multi-classification Logistic regression analysis to analyze its impact. [Results] A total of 2001 people were surveyed in the baseline of the study. A total of 1791 valid samples were followed up (10.49% of the respondents). During the study period, the detection rate of the intervention group, the condom use rate were significantly higher than the control group. The multivariate Logistic regression analysis showed that the adjusted OR of the intervention was 4.280 and the 95% confidence interval was 2.912-6.291. Multivariate analysis of condom use in the last 3 sexes showed that the OR of intervention was 2.483, The 95% confidence interval is 1.226 ~ 5.028. [Conclusion] The intervention project has achieved some results, which has facilitated the inspection of the IUD for the floating population and the correct use of the condom.
