Factors associated with stress among pregnant women with a second child in Hunan province under China's two-child policy: a mixed-method study

OBJECTIVE

The purpose of the study was to investigate the status of pregnancy stress and to explore factors associated with pregnancy stress among women by China's two-child policy.

METHODS

A mixed-method study involving both quantitative and qualitative methods was conducted using questionnaires and semi-structured interviews. The questionnaires encompassed socio-demographic and obstetric characteristics, as well as the Pregnancy Stress Rating Scale (PSRS) and the Social Support Rating Scale (SSRS). Initially, the participants were required to complete the questionnaires, enabling us to assess their respective pregnancy stress statuses. Subsequently, we selectively interviewed pregnant women with a second child and exhibited at least mild pregnancy stress. The qualitative study sought to uncover the factors contributing to their stress during pregnancy.

RESULTS

A total of 463 subjects were enrolled; of the subjects, 22 (4.8%) had no stress, 407 (87.9%) had mild stress, 34 (7.3%) had moderate stress. Generalized linear regression analysis revealed significant factors (P<0.05) related to pregnancy stress, including family financial burden, subjective support, fertility desire, gender of the first child, and gender preference. Additionally, 16 subjects were interviewed, and through analysis, three major themes emerged, each comprising 12 sub-themes associated with pregnancy stress. These themes were identified as fertility factors (worry about maternal and child health, birth experience, and parenting stress), family factors ( financial burden, second child care problems, first child's acceptance of the second child, family concerns, fertility desire, and gender preference) and social factors (involving life events, career development and workload).

CONCLUSION

The diver factors contribute to pregnancy stress among pregnant women under China's two-child policy. Our study could be used to develop appropriate interventions to reduce pregnancy stress and to enhance the mental health of women pregnant with a second child.

The impact of China's universal two-child policy on total, preterm, and multiple births: a nationwide interrupted time-series analysis

BACKGROUND

Although years have passed since the implementation of China's universal two-child policy, the effectiveness of this policy remains unclear. To address this knowledge gap, we, here, assessed the impact of the two-child policy on total live births, preterm births, and multiple live births.

METHODS

Data identifying pregnancies resulting in at least one live birth between April 1 2013 and December 31 2018 were collected from the Hospital Quality Monitoring System database. Using an interrupted time-series analysis, we estimated immediate level changes and long-term trends in total, preterm (birth before 37 weeks' gestation), and multiple live births that had occurred after July 2016, when the universal two-child policy had taken effect.

RESULTS

A total of 8,273,622 live births were reported during the study time frame. The number of live births (p = 0.277), preterm births (p = 0.052), and multiple births (p = 0.856) per month slightly increased immediately after July 2016, but these increases did not meet statistical significance. Further, all three outcomes showed a significant downward trend that lasted until the end of 2018 (p < 0.0001 for all). Among all live births, the percentage of preterm births remained stable (p = 0.101), while the percentage of multiple live births that were preterm significantly increased (trend change = 0.21% per month, 95% CI 0.14 to 0.28, p < 0.0001). The percentage of live multiple births among all live births significantly decreased (p for trend = 0.0039).

CONCLUSIONS

Overall, our data reveal a transient baby boom, as well as an increase in the proportion of live multiple births that were preterm, after China's two-child policy took effect. The latter should be noted by healthcare professionals due to the high risk of complications and special medical care required by preterm babies.
