摘      要：Objective:To analyze the temporal trends of maternal mortality ratio(MMR)due to obstetric hemorrhage and its specific causes in Chinese mainland from 2000 to 2019,to identify whether the rate of change has accelerated or slowed down during this period,and to find the prior cause of obstetric hemorrhage that needs to be intervened in the ***:Individual information on maternal deaths and total number of live births from 336 surveillance sites across 31 provinces in Chinese mainland was collected from the National Maternal and Child Health Surveillance System between 2000 and *** death was defined according to the World Health Organization’s *** final underlying cause of death was confirmed by the national review and was coded according to International Classification of *** trends for changes in characteristics of maternal deaths were assessed using linear or logistic models with the year treated as a continuous *** MMR and 95%confidence intervals(CI)for regions or causes were estimated by Poisson’s *** regression was used to assess the accurate temporal ***:The national MMR due to obstetric hemorrhage was 18.4 per 100,000 live births(95%CI:15.0–22.2)in *** peaked in 2001(22.1 per 100,000 live births,95%CI:18.3–26.4)and was lowest in 2019(1.6 per 100,000 live births,95%CI:1.0–2.3).For specific regions,the MMR due to obstetric hemorrhage in rural areas and western regions both experienced a slight rise,followed by a rapid decline,and then a slow *** specific causes,no change point was found in joinpoint analysis of the national MMR caused by placenta previa,postpartum uterine atony,and retained placenta(the annual percent change was
12.0%,
10.5%,and
21.0%,respectively).The MMR caused by postpartum hemorrhages(PPH)significantly declined by 8.0%(95%CI:1.9–13.6)per year from 2000 to *** annual percent change of MMR caused by PPH accelerated further to
