南通市区中期妊娠引产状况调查与分析

摘要

目的：通过对近两年来中期妊娠引产的原因进行调查，了解其人群分布特点，对重点人群进行教育干预，以期达到降低中期妊娠引产的发生。方法选择2010年10月至2012年10月在南通大学附属妇幼保健院进行中期妊娠引产的568例患者为研究对象，对其年龄、婚姻状况、生育史、避孕史、居住地、职业等进行调查，运用描述统计、χ2检验的方法进行分析。结果在568例中期妊娠引产妇女中有流动人口400人，占引产总人数的70．42％，其中未婚215例，占引产总人数的37．85％；已婚的流动人口231人，占引产总人数的40．67％，未婚的流动人口169人，占引产总人数的29．75％。胎儿畸形引产52例，占引产总人数的9．15％。本地人口、流动人口引产者中未婚、无职业的比例比较均具有显著性差异（χ2值分别为11．12、25．94，均P＜0．01）。结论已婚、无业的流动人口是中期妊娠引产的主要人群；其次是未婚的流动人口；随着产前筛查水平的提高，胎儿畸形引产的比例已近10％。因此，加强对流动人口的计划生育管理是减少中期妊娠引产的最重要环节。%Objective To reduce the incidence of induced abortion in second trimester through investigating the causes of induced abortion in second trimester performed in last two years , understanding its population distribution characteristics , and providing educational intervention for the population .Methods From October 2010 to October 2012 568 patients underwent induced abortion in second trimester in Nantong University Affiliated Maternal and Child Health Hospital , and they were recruited for the study .Patients’ age, marital status, reproductive history , contraceptive history , residence and occupation were investigated and analyzed using descriptive statistics and chi -square test methods.Results Among 568 women with induced abortion in second trimester , 400 (70.42%) were floating population, of whom 215 (37.85%) were unmarried.There were 231 married floating people, accounting for 40.67%, and there were 169 unmarried floating people, accounting for 29.75%.There were 52 cases with fetal malformations, accounting for 9.15% of the total number of induced abortion .There were significant differences in the proportions of unmarried and unemployed people between native population and floating population undergoing induced abortion (χ2 value was 11.12 and 25.94, respectively, both P<0.01).Conclusion The married and unemployed floating populations are the main people with induced abortion in second trimester , followed by unmarried floating population .With the improvement of prenatal screening level , the proportion of induced abortion of malformed fetuses is nearly 10%.
