Abstract

<abstract> <title>Abstract</title> <p> <italic>Objective</italic>: To estimate birth population-based perinatal-neonatal mortality and preterm rate in China from a regional survey in 2010.</p> <p> <italic>Study design</italic>: Data of total births in 2010 obtained from 151 level I–III hospitals in Huai'an, Jiangsu, were prospectively collected and analyzed.</p> <p> <italic>Results</italic>: From 61 227 birth registries (including 60 986 live births and 241 stillbirths), we derive a birth rate of 11.3‰ (of 5.4 million regional population), a male-to-female ratio of 116:100 and valid data from 60 615 newborns. Mean birth weight (BW) was 3441 ± 491 g with 13.6% macrosomia. Low BW was 2.8% (1691/60 372) with 8.83% mortality. Preterm rate was 3.72% (2239/60 264) with 7.61% mortality. Cesarean section rate was 52.9% (31 964/60 445), multiple pregnancy 1.8% (1088/60 567) and birth defects 6.7‰ (411/61 227). There were 97.4% healthy newborns and 2.2% (1298) requiring hospitalized after birth. The perinatal mortality was 7.7‰ (471/61 227, including 241 stillbirths, 230 early neonatal deaths). The neonatal mortality was 4.4‰ (269/60 986). The main causes of neonatal death were birth asphyxia (24.5%), respiratory diseases (21.5%), prematurity related organ dysfunction (18.5%) and congenital anomalies (7.7%), whereas incidence of congenital heart disease and respiratory distress syndrome was 8.6‰ and 6.1‰, respectively.</p> <p> <italic>Conclusions</italic>: This regional birth population-based data file contains low perinatal-neonatal mortality rates, associated with low proportion of LBW and preterm births, and incidences of major neonatal disease, by which we estimate, in a nationwide perspective, in 16 million annual births, preterm births should be around 800 000, perinatal and neonatal mortality may be 128 000–144 000 and 80 000–96 000, respectively, along with 100 000 respiratory distress syndrome.</p> </abstract>
