Analysis of the causes of premature birth, asphyxia of prematurity, perinatal morbidity and mortality. Results: Premature rupture of membranes, unexplained, placenta previa, pregnancy-induced hypertension syndrome in the top four.

The perinatal mortality rate was 243.0 ‰, indicating that the perinatal mortality rate of preterm birth was significantly higher than that of natural premature birth. <32 weeks gestational age, body weight <1500g, perinatal mortality greater than 500 ‰.
