The incidence, characteristics, and complications of pregnant women who delivered stillbirths under different child policies in central China.

ABSTRACT:

Background

China's evolving fertility policies (one-child to three-child) have shaped maternal and neonatal outcomes, but specific gaps in stillbirth epidemiology during policy transitions.

Methods

This retrospective cohort study analyzed 721,860 singleton pregnancies in 2011-2023, from 18 maternal near-miss surveillance hospitals in Hunan. Stillbirth rates were assessed across four policy periods: one-child (2011-2013), partial two-child (2013-2015), universal two-child (2016-2020), and three-child (2021-2023). Multivariable logistic regression identified risk factors, adjusting for fertility policy period, maternal demographics and maternal comorbidities. Trends over time were analyzed using segmented regression models.

Results

The overall stillbirth rate was 7.02‰
