目的调查上海市未婚青少年重复人工流产的影响因素。方法采用横断面研究,对上海市10家医院门诊终止早期意外妊娠的≤24周岁未婚女性进行匿名问卷调查,并分析资料。结果2343名对象填写了完整问卷,重复人工流产率为38.5%,1年内重复人工流产率为23.5%,高危手术因素为40.2%。年龄>19岁、无职业、文化程度偏低、男朋友年龄偏大以及未婚同居的对象重复流产的危险性高(OR>1)。流产后未更换男朋友及近1年内无任何避孕措施的对象1年内重复流产的危险性高(OR>1)。结论人工流产后没有落实可靠避孕措施是再次意外妊娠的主要原因,无职业、文化程度低的社会弱势群体,同时男朋友年龄较大、未婚同居者,应成为干预的重点人群;鼓励男性参与和落实可靠避孕措施应成为干预的重点措施;流产后1年内应成为干预的重点阶段。
Objective To investigate the influencing factors of repeated induced abortion in Shanghai unmarried adolescents. Methods A cross-sectional study was conducted to conduct anonymous questionnaire survey of unmarried women ≤24 years of age who terminated early unplanned pregnancy in 10 hospitals in Shanghai and analyzed the data. Results A total of 2343 subjects completed the questionnaire. The rate of repeated abortion was 38.5%. The rate of repeated abortion in one year was 23.5% and that of high-risk operation was 40.2%. Patients> 19 years of age who were unemployed, under-educated, older boyfriends and unmarried cohabiters had a high risk of repeat abortion (OR> 1). The risk of repeated abortion within 1 year is high (OR> 1) for those who have not changed their boyfriend after abortion and those who have not had any contraceptives in the recent 1 year. Conclusions Failure to implement reliable contraception after abortion is the main reason for another unwanted pregnancy. There is no social vulnerable group with low occupation and education level. At the same time, the older boyfriends and unmarried cohabitants should be the focus groups for interventions. Encouragement of male participation and The implementation of reliable contraceptive measures should become the focus of intervention measures; one year after abortion should become the focus of intervention phase.
