Repeat induced abortion in 30 Chinese provinces: A cross-sectional study

Characteristics and contraceptive practices among Chinese women seeking abortion: a multicentre, descriptive study from 2019 to 2021

INTRODUCTION

Despite the widespread provision of free contraceptives and post-abortion care (PAC) services, China grapples with a high rate of unintended pregnancies and subsequent abortions. We aimed to study the evolving characteristics of women seeking abortion and their contraceptive practices before and after abortions, to shed light on the optimisation of Chinese PAC services.

METHODS

This study utilised data from an abortion cohort between 2019 and 2021. We studied their demographic features, contraception and abortion histories, reasons and choices using chi-square or linear-by-linear tests. We also explored the potential impact of receiving services at PAC facilities on post-abortion contraception use and repeat abortions using logistic regression models.

RESULTS

Among the 9005 participants, 43.4% experienced repeat abortion, without a discernible trend over the 3 years. Noteworthy increases were observed in the percentages of college students (from 1.7% to 6.6%, p<0.01) and middle-aged women (from 23.2% to 26.8%, p<0.01) seeking abortions. Surgical abortion was chosen by nearly 90% of participants with a continuously increasing trend (p trend <0.01). Nearly half of the participants experienced unintended pregnancies due to non-use of contraception. Of the remainder, the majority preferred less or the least effective methods both before and after abortion. Women residing in moderate-gross domestic product (GDP) regions faced a higher risk of repeat abortions (OR 1.33, 95% CI 1.16 to 1.54). Despite this, high-quality PAC services may encourage the use of reliable contraceptive methods, with 86.8% of women changing from least effective or no methods to (most) effective methods post-abortion, and prevent repeat abortions (OR 0.65, 95% CI 0.56 to 0.75).

CONCLUSIONS

Increased proportions of college students and middle-aged multiparous women seeking abortions were observed, together with inappropriate preferences for less effective contraception and increasing choice of surgical abortions. Future research should extend the focus to cover the entire abortion period, advocate the rational selection of contraceptive methods, and emphasise the specified PAC services tailored to different socioeconomic groups.

Knowledge, attitude and practice of contraceptive methods among women with an unplanned pregnancy

OBJECTIVES

The study aimed to investigate the knowledge, attitude and practice (KAP) of contraceptive methods among women with an unplanned pregnancy, aiming to improve their reproductive health and increase their understanding of contraceptive methods.

DESIGN

This is a cross-sectional study.

SETTING

The study was conducted at the Maternity and Child Healthcare Hospital of Hubei between 20 November 2022 and 20 January 2023.

PARTICIPANTS

Women with an unplanned pregnancy were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

The questionnaire was in the Chinese language and included demographic data, KAP assessments. Multivariate linear regression was performed to explore the factors associated with knowledge or practice scores.

RESULTS

During the study period, 510 participants with valid questionnaires were included. The KAP scores were 7.30±2.91, 32.61±3.13 and 28.58±3.59, respectively. Place of residence (urban vs non-urban; B=0.66, 95% CI 0.02 to 1.29, p=0.043) and educational level (master's degree or above vs post secondary or below; B=1.07, 95% CI 0.17 to 1.96, p=0.020) were positively associated with knowledge. Knowledge (B=0.25, 95% CI 0.17 to 0.32, p<0.001) and attitude (B=0.26, 95% CI 0.19 to 0.32, p<0.001) were positively associated with practice.

CONCLUSIONS

This study indicates a low level of KAP regarding contraceptive methods among women facing unplanned pregnancies. Place of residence and educational level were positively associated with knowledge scores. These findings may help improve future sex education policies and programmes.

The body mass index and the risk of ectopic pregnancy: a 5-year retrospective case-control study

PURPOSE

Acknowledging the associated risk factors may have a positive impact on reducing the incidence of ectopic pregnancy (EP). In recent years, body mass index (BMI) has been mentioned in research. However, few studies are available and controversial on the relationship between EP and BMI.

METHODS

We retrospectively studied the EP women as a case group and the deliveries as a control group in the central hospital of Wuhan during 2017 ~ 2021. χ2 test of variables associated with ectopic pregnancy was performed to find differences. Univariate and multivariate binary logistic regression analysis was conducted to analyze the association of the variables of age, parity, history of induced abortion, history of ectopic pregnancy, history of spontaneous abortion, history of appendectomy surgery and BMI (< 18.5 kg/m2, 18.5 ~ 24.9 kg/m2, 25 kg/m2 ~ 29.9 kg/m2, ≥ 30 kg /m2) with EP.

RESULTS

They were 659 EP and 1460 deliveries. The variables of age, parity, history of induced abortion, history of ectopic pregnancy and BMI were different significantly(P < 0.05). Multivariate analysis showed that the variables of age > 35 years old [(OR (Odds Ratio), 5.415; 95%CI (Confidence Interval), 4.006 ~ 7.320, P < 0.001], history of ectopic pregnancy (OR, 3.944; 95%CI, 2.405 ~ 6.467; P < 0.001), history of induced abortion(OR, 3.365; 95%CI, 2.724 ~ 4.158, P < 0.001) and low BMI (< 18.5 kg/m2) (OR, 1.929; 95%CI, 1.416 ~ 2.628, P < 0.001])increased the risk of EP.

CONCLUSION

The history of ectopic pregnancy, history of induced abortion and age > 35 years old were the risk factors with EP. In addition to these traditional factors, we found low BMI (< 18.5 kg/m2) with women may increase the risk to EP.

Impact of the intensive psychological intervention care on post-traumatic stress disorder and negative emotions of teenage female patients seeking an induced abortion

Aim

This study aimed to investigate the effects of intensive psychological intervention care on adverse emotions and post-traumatic stress disorder (PTSD) symptoms in female teenage patients after induced abortion.

Methods

This prospective cohort study included 100 teenage female patients seeking induced abortion who were randomly divided into two groups: the intervention group (n = 50) and the control group (n = 50). The intervention group received intensive psychological intervention care, while the control group received standard routine nursing. The scores of the PTSD checklist for DSM-5 (PCL-5), self-rating depression (SDS), and self-rating anxiety scale (SAS) were compared between the two groups at 1 month and 3 months after the operation.

Results

The intervention group had lower risk of developing PTSD (24% vs. 44%), depression (10% vs. 32%), and anxiety (0% vs. 12%) symptoms at 1 month after the surgery. However, there were no significant differences observed between the two groups at 3 months after the surgery. Furthermore, the intervention group had significantly lower scores in PCL-5 (27.4 ± 5.4 vs. 31.8 ± 5.7; 20.5 ± 7.1 vs. 25.0 ± 7.5; p < 0.05), SDS (31.8 ± 5.4 vs. 37.8 ± 6.6; 26.8 ± 5.0 vs. 31.4 ± 7.2; p < 0.05), and SAS (32.7 ± 5.0 vs. 39.8 ± 6.9; 25.0 ± 2.7 vs. 27.5 ± 2.8; p < 0.05) at 1 month and 3 months after induced abortion.

Conclusion

These findings suggest that intensive psychological intervention care can reduce the incidence and severity of depression, anxiety, and PTSD symptoms in teenage patients who undergo induced abortion.

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

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.

Prevalence of stress and depression and associated factors among women seeking a first-trimester induced abortion in China: a cross-sectional study

Objectives

To determine the prevalence of stress and depression and associated factors among women seeking a first-trimester induced abortion in China.

Methods

A cross-sectional study was conducted in a tertiary hospital in Beijing, from April 1st to Oct 31st, 2021. Women seeking termination of an intrauterine first-trimester pregnancy were invited to participate and complete a digital self-administered questionnaire. The survey included socio-demographic and health questions, Perceived Stress Scale-10 (PSS-10), and Patient Health Questionnaire-9 (PHQ-9). Descriptive analyses and binary logistic regression analyses were performed using SPSS 23.0.

Results

A total of 253 women participated. Prevalence of high perceived stress (cut-off ≥ 20) and depressive symptoms (cut-off ≥ 10) was 25.3% and 22.5%, respectively. Women were more likely to suffer high stress if they reported low resilience (aOR = 16.84, 95% CI 5.18–54.79), were not-using contraceptives (aOR = 3.27, 95% CI 1.39–6.29), had low social support (aOR = 2.95, 95% CI 1.39–6.29), were non-local residents (aOR = 2.51, 95% CI 1.15–5.92), were dissatisfied with their intimate relationship (aOR = 2.44, 95% CI 1.15–5.16), or held pro-life attitudes towards abortion (aOR = 1.04, 95% CI 1.18–3.53). Odds of experiencing depression were higher among women who also reported high perceived stress (aOR = 19.00, 95% CI 7.67–47.09), had completed higher education (aOR = 12.28, 95% CI 1.24–121.20), and were non-local residents (aOR = 3.38, 95% CI 1.37–8.32).

Conclusions

The magnitude of perceived stress and depression was high among Chinese women seeking a first-trimester induced abortion. It is necessary to comprehensively evaluate the mental health of women seeking an abortion, especially those with high risk. Interventions to mitigate relevant associated factors could improve the psychological wellbeing of women.

Abortion is a stressful life event. Understanding how women perceive having an abortion and their psychosocial responses will enable health providers to understand women’s needs and provide high-quality care. This study aims to determine the frequency of stress and depression among women seeking an induced abortion in early pregnancy in China and associated factors Around 25.3% of women reported high stress and 22.5% reported depression. Women were more likely to suffer high stress if they reported low resilience, were not-using contraceptives, had low social support, were non-local residents, were unhappy with their intimate relationship, or held pro-life attitudes towards abortion. High perceived stress, high education level, and non-local status were associated with depression. The findings indicate stress and depression are quite common among women seeking an abortion in China, especially those with high-risk factors. It is necessary to evaluate and promote the mental health of women seeking an abortion.

Repeat Induced Abortion among Chinese Women Seeking Abortion: Two Cross Sectional Studies

Background: In China, there were about 9.76 million induced abortions in 2019, 50% of which were repeat abortions. Understanding the tendency of repeat induced abortion and identifying its related factors is needed to develop prevention strategies. Methods: Two hospital-based cross-sectional surveys were conducted from 2005–2007 and 2013–2016 in 24 and 90 hospitals, respectively. The survey included women who sought an induced abortion within 12 weeks of pregnancy. The proportion of repeat induced abortions by adjusting the covariates through propensity score matching was compared between the two surveys, and the zero-inflated negative binomial regression model was established to identify independent factors of repeat induced abortion. Results: Adjusting the age, occupation, education, marital status and number of children, the proportion of repeat induced abortions in the second survey was found to be low (60.28% vs. 11.11%), however the unadjusted proportion was high in the second survey (44.97% vs. 51.54%). The risk of repeat induced abortion was higher among married women and women with children [OR_adj and 95% CI: 0.31 (0.20, 0.49) and 0.08 (0.05, 0.13)]; the risk among service industry staff was higher when compared with unemployed women [OR_adj and 95% CI: 0.19 (0.07, 0.54)]; women with a lower education level were at a higher risk of a repeat induced abortion (OR_adj < 1). Compared with women under the age of 20, women in other higher age groups had a higher frequency of repeat induced abortions (IR_adj: 1.78, 2.55, 3.27, 4.01, and 3.93, separately); the frequency of women with lower education levels was higher than those with a university or higher education level (IR_adj > 1); the repeat induced abortion frequency of married women was 0.93 (0.90, 0.98) when compared to the frequency of unmarried women, while the frequency of women with children was 1.17 (1.10, 1.25) of childless women; the induced abortion frequency of working women was about 60–95% with that of unemployed women. Conclusions: The repeat induced abortion proportion was lower than 10 years ago. Induced abortion seekers who were married, aged 20 to 30 years and with a lower education level were more likely to repeat induced abortions.
