This research aims to analyze the maternal mortality transition in China and the subnational disparities between GBD 2023 estimates and NMMSS data from 1990 to 2023.
Integrated model-based GBD estimates with National Maternal Mortality Surveillance System (NMMSS) data.
Used Joinpoint regression to identify changes in temporal trends.
Applied Bayesian age-period-cohort models for scenario-based projections toward Healthy China 2030 target.
GBD estimates showed a decline in China's maternal mortality ratio from 121.9 (1990) to 10.7 (2023) per 100,000 live births; NMMSS reported 15.1 per 100,000 live births in 2023.
Leading causes shifted from maternal hemorrhage (GBD) to consistently identified obstetric hemorrhage (NMMSS).
Urban-rural disparities narrowed significantly, yet subnational inequities persist, particularly in western provinces.
