To explore the epidemiological analysis of complications in premature infants.

From January 2017 to March 2018, 1800 premature babies in Ningbo Women and Children Hospital were selected in the study.The clinical data of pregnant women, premature infants and premature complications, and so on were investigated, and summarized epidemiology of premature infant complications.

The probability of premature birth was 9.09%.The differences between different gestational age(χ²=2 481.34) and different body weight(χ²=3 088.21) were statistically significant(all P<0.05). Premature rupture of membranes occurred as the main one of the common factors lead to premature birth, the fetal distress was also more common factors, so in different gestational age, the difference was not statistically significant(P>0.05). However, compared with other factors, the difference of premature infants at different gestational weeks was statistically significant(P<0.05).

Epidemiological study of preterm infants, can promote their perinatal management level and quality, and then pointed to strengthen perinatal health education and health care, for the effective prevention and treatment of common diseases of perinatal, key management and monitoring work earnestly strengthen the high-risk pregnancy, attaches great importance to the establishment of collaborative relationship between made in pediatric claims intrauterine transhipment, making pregnant women can be produced in the hospital for treatment for premature babies, and reduce the mortality and morbidity rates of premature and low birth weight, can reduce the risk of intellectual disability, eventually making the birth population overall quality improved.
