尽管中国每年有超过1000万例人工流产,很少有全面的,系统,以及中国女性人工流产的特征数据。本研究旨在研究中国人工流产的总体趋势,并分析人工流产与一些社会经济因素之间的相关性。
来自2017年中国生育率调查,这项研究从周期和队列的角度对240,957名女性进行了多项指标分析.指标包括流产率和比例,人工流产时的平均年龄,特定年龄的累积比例,以及按队列划分的人工流产数量。分析还根据居住情况进行了区分,种族,教育水平,和婚姻状况。使用二项逻辑回归模型来检查人工流产与社会经济因素之间的关联。
在2006年至2016年期间,在15-49岁的女性中,人工流产率和人工流产妇女的平均年龄有所增加,但堕胎比例下降。婚前妊娠中人工流产的比例高于婚后妊娠,意外怀孕而不是计划怀孕。有人工流产经历的妇女占所有队列的不到30%,每个队列中每名女性的累计人工流产次数小于0.45.这些指标因出生队列而异,residence,种族,教育水平,和婚姻状况。二项逻辑回归的结果证实了人工流产与这些社会经济变量之间的关联。女性胎儿的性别选择性流产仍然存在,尽管政府付出了巨大的努力来消除它们。
人工流产的做法因群体和社会经济特征而异。中国堕胎妇女的形象已经从受过良好教育的城市妇女转向农村,受教育程度较低的妇女。政府应采取更有效的措施,减少堕胎风险较高的妇女的人工流产数量。
Although there are more than 10 million induced abortions per year in China, there are few comprehensive, systematic, and characteristic-based data on induced abortions among Chinese women. This study aims to examine the overall trend in induced abortions in China and to analyze the correlation between induced abortions and some socio-economic factors.
Drawing from the 2017 China Fertility Survey, this study analyzed induced abortions using multiple indicators from period and cohort perspectives on a sample of 240,957 women. The indicators include the abortion rate and proportion, average age at the time of induced abortion, age-specific cumulative proportions, and the number of induced abortions by cohort. The analysis also differentiated based on residency, ethnicity, education level, and marital status. A binomial logistic regression model was used to examine the association between induced abortions and socio-economic factors.
Between 2006 and 2016, among women aged 15-49, there was an increase in the induced abortion rate and the average age of women who had induced abortions, but a decline in the proportion of abortions. The proportion of induced abortion was higher among premarital than post-marital pregnancies, among unintended than planned pregnancies. Women with induced abortion experiences accounted for less than 30% of all cohorts, and the cumulative number of induced abortions per woman in each cohort was less than 0.45. These indicators varied with birth cohort, residence, ethnicity, education level, and marital status. The results of binomial logistic regression confirmed the association between induced abortion and these socio-economic variables. Sex-selective abortions of female fetuses still exist, despite the government\'s considerable efforts to eliminate them.
The practice of induced abortions differs by cohort and socio-economic characteristics. The profile of women who resort to abortions in China has shifted from well-educated urban women to rural, less-educated women. More effective measures should be taken by the government to reduce the number of induced abortions among women with higher abortion risks.
