Introduction: Premature birth is the most common cause of neonatal mortality and childhood disability, occurring in most cases without a known medical cause, and is an obstetrics complication with complex causes. It is necessary to identify the reasons of preterm birth to predict it and decrease amount of morbidity and mortality of mothers and their infants.
Methods: the study was performed on 7747 cases of mothers who gave birth with in 2016-2017 . 2000 of them which have not included criteria so they excluded from the study. we used a researcher-made checklist based on scientific texts and articles to generate information of their pregnancies and births.The final checklist data was entered in SPSS software version 16. .Logistic regression model was used to determine the factors associated with preterm birth.
Results: we realized that there are significant associations between some risk factors during pregnancy and preterm birth. maternal age older than 35 years old has a significant association with preterm birth (p=0.001). Multiple pregnancies were associated with preterm delivery(p<0.001). Preterm births were increased in mothers who had diabetes pregnancy (p<0.001). there is a significant association between multi-parity and preterm birth (p=0.01).
Conclusion: Maternal age, multiple pregnancy, disease and parity are associated with preterm birth ; thus, identity and prediction preterm delivery to prevent mortality and morbidity mothers and infants are important.
