Abstract：Objective To explore the different types of the premature delivery rate, related factors and pregnancy outcome.Methods From January 2009 to December 2013,clinical data different types of preterm birth pregnant women and neonates in department of gynecology and obstetrics,Xuanwu Hospital of Capital University of Medical Sciences were collected, for different groups of pregnant women ( preterm premature rupture of membranes group was 301 cases, preterm labor group was 234 cases, iatrogenic preterm group was 193 cases) , complications, mode of delivery and the data of the newborn were compared.Results From 2009 to 2013, complications and preterm birth rate were increased year by year.Iatrogenic preterm labor group’ s age,the rate of cesarean section maternal,Apgar score abnormal rate and complications were significantly higher than that of the preterm labor group and preterm premature rupture of membranes group ( P <0.05), and gestational age, birth weight were less than preterm delivery group, preterm premature rupture of membranes group ( P <0.05);3 groups of preterm’ s parous women and not carried out prenatal examination’ s women were obviously higher than that of primipara and received antenatal examination subjects ( P <0.01) , iatrogenic preterm group of preterm’ s parous women and not carried out prenatal examination’s women’ prenatal premature occurrence rate were higher than that of preterm premature rupture of membranes group and preterm delivery group ( P <0.05).Iatrogenic preterm delivery group’s patients with hypertensive dis-order were 67.36%(130/193), placental factors accounted for 15.54%(30/193), fetal factors accounted for 7.77%(15/193), the others was 9.33%(18/193).Conclusion Preterm birth rate has increased year by year, iatrogenic preterm birth, preterm premature rupture of membranes are important factor of preterm birth, while decrease the iatrogenic preterm labor is vital to reduce the rate of premature delivery.
