江苏省已婚育龄妇女的人工流产分布模式及其影响因素

Study on the distribution and affect factors of induced abortion among married women in Jiangsu province

目的 :了解江苏省已婚育龄妇女的人工流产的实际发生率 ,及其分布模式和影响因素 ,为采取相应的干预措施提供依据。方法 :应用多阶段分层整群随机抽样方法 ,在全省范围内抽取2 6个调查点 ,调查了符合条件的对象 112 6 9人。由经省培训的调查员 ,采用统一信息表逐户登门询问调查。结果 :我省已婚育龄妇女中进行过人工流产者占总数的 2 7 0 7% ;1999年人工流产率为12 1‰。导致我省已婚育龄妇女人工流产的原因主要是避孕失败和非意愿妊娠 ,占 86 86 %。单因素分析表明 :人工流产组初婚年龄及初产年龄均明显低于非人工流产组 ;年龄越大发生过人工流产的可能性越大 ;男孩数少的妇女更有可能发生过人工流产 ;不同职业人流率存在显著差异 ,其中以工人和农牧渔民最高 (χ2 =92 2 8,P <0 0 1)。多因素非条件logistic回归分析提示年龄、农民、工人、文化程度为人工流产的危险因素 (其OR值分别为 1 0 4 6 ,1 5 36 ,1 5 5 4和 1 133) ,而初产年龄和男孩数为保护因素 (其OR值分别为 0 94 6和 0 5 95 )。结论 :本省已婚育龄妇女的总人工流产率和年人工流产率均低于全国平均水平 ,但高于香港和欧美发达国家 ,说明本省的人工流产现象仍较常见 ,应该采取有效措施 ,降低人工流产率 ,切实保护妇女生殖健康。

Objective: To learn the incidence rate, distribution and affect factors of induced abortion in Jiangsu province so as to take specified measurements for intervention. Method: Multi-stage, stratified, cluster randomization is used to select 26 townships in the province. Well-trained interviewers interviewed 11,269 eligible women, and information was collected from every household using the same questionnaire. Result: 27.07% of the married women have the experience of abortion; the annual abortion rate in 1999 is 12.1‰. Contraceptive failure and unwilling pregnancy counted up to 86.86%, are major causes of abortion. Single variable analysis shows that the age of first marriage and the age of first delivery of abortion group are significantly younger than that of the none-abortion group; The probability of abortion was often high with the age of the women increased, as well as the women have fewer boys; among the workers and farmers are high rate of the abortion various professionals (χ 2=92.28, P <0.01). Multivariate unconditional logistic regression indicates that the risk factors include the age, profession and education level (OR=1.046, 1.536, 1.554 and 1.133, respectively), while the protective factors are age of first delivery, and the number of boys the women own (OR=0.946, 0.595, respectively). Conclusion: The total and annual abortion rates of Jiangsu province are lower than that of the national level, but higher than that of the developed countries. The study shows that induced abortion is still a provincially phenomenon that needs to be well controlled by effective interventions to promote the reproductive health of women.
