Recent trend and correlates of induced abortion in China: evidence from the 2017 China Fertility Survey

Abstract

Abstract Background 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. Methods 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. Results 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. Conclusion 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.
