目的:了解江西省南昌市已婚育龄妇女人工流产人数率及其人群分布情况。方法:采用多阶段分层随机抽样方法抽取南昌市2县(进贤县、安义县)2区(青山湖区、西湖区)5468例已婚育龄妇女,对其2004年7～12月的社会人口学特征、婚姻、生育状况进行问卷调查。结果:随着年龄的增加,人工流产的人数率亦增加(P<0.001);初孕年龄在20～24岁和25～29岁年龄段的人工流产人数率较高(P<0.001);结婚年数在10～14年和15～19年的人工流产人数率较高(P<0.001);随着妊娠次数的增加,人工流产的人数率亦增加(P<0.001);教师和专业技术人员的人工流产人数率较高(P<0.001);文化程度越高,人工流产人数率越高(P<0.001);居住城镇的人工流产人数率明显高于乡村(P<0.001);有避孕的人工流产人数率明显高于无避孕的(P<0.001)。在各年龄段,随着人工流产次数的增加,人工流产的人数和人次率均逐渐减少,人工流产1次的人次率在30～34岁和35～39岁年龄段较高(P<0.001)。两分类Logistic回归分析显示,结婚年数、专业技术人员和教师是人工流产的危险性因素,行政干部有人工流产的危险趋势;文化程度越低、初孕年龄越大、家庭人年均收入越低,以及居住农村,则人工流产率越低。结论:晚育可以减少人工流产的发生;预防人工流产发生的重点人群为初孕年龄在20～29岁年龄段和居住城镇的育龄妇女,以及专业技术人员、教师和行政干部等较高学历者。避免婚后第二次及以上妊娠是预防人工流产的重要举措。
OBJECTIVE: To understand the rate of abortion and the distribution of its population in married women of childbearing age in Nanchang, Jiangxi Province. Methods: 5468 married women of childbearing age in 2 districts (Qingshan Lake and Xihu District) of 2 counties (Jinxian County and Anyi County) in Nanchang were enrolled in this study. The women of childbearing age from July to December in 2004 Demographic characteristics, marital status and fertility survey. Results: The number of induced abortion increased with age (P <0.001). The incidence of induced abortion was significantly higher in first trimester women aged 20-24 years and 25-29 years (P <0.001) The number of induced abortions was higher in years 10-14 and 15-19 (P <0.001); the number of abortions increased with the number of pregnancies (P <0.001); the number of teachers and professional technicians (P <0.001); the higher the education level, the higher the rate of induced abortion (P <0.001); the rate of induced abortion in urban areas was significantly higher than that in rural areas (P <0.001); the rate of artificial abortion Abortion rate was significantly higher than without contraception (P <0.001). At all ages, with the increase of the number of induced abortions, the number of abortion and the number of visits decreased gradually. The incidence of abortion was higher in 30-34 and 35-39 age groups (P <0.001) . Logistic regression analysis showed that the number of years of marriage, professional technicians and teachers were the risk factors of abortion and that of administrative cadres was the risk of induced abortion. The lower the educational level, the higher the age of first trimester, the lower the average annual income of family members , As well as living in rural areas, the lower the rate of induced abortion. Conclusion: Late childbearing can reduce the incidence of induced abortion. The key population for prevention of induced abortion is the women of childbearing age and the higher educated persons such as professional technicians, teachers and administrative cadres who are 20 to 29 years old and living in urban areas. Avoiding second and subsequent pregnancies is an important measure to prevent induced abortion.
