Background: Preterm birth is the leading cause of neonatal mortality and a major public health concern. This study aimed to determine factors influencing preterm labor in women referring to hospitals in Khorramabad in 2009-10. Materials and Methods: This case-control study was conducted on 524 mothers (262 subjects in each group) referring to hospitals in Khorramabad (west of Iran) in 2009-10, selected through consecutive sampling. A questionnaire was completed through interviews for each newborn after being examined. Collected data, were analyzed by using the logistic regression and odds ratios and a significant level of 5%. The logistic regression model sensitivity in detecting cases of preterm labor was 86%. Results: The frequency of preterm labor in mothers under 20 was 5.83 times higher than that in mothers in the age range of 20-35 (CI=2.99, 11.37, and P < 0.001). The odds ratios for preterm birth were highest for multiple pregnancies and preterm delivery in mothers with a history of obstetric complications as preterm delivery, low birth weight, stillbirth and abortion is seen more than that in other mothers. Conclusion: These findings will be useful for medical staff and public health workers in attempting to identification and management of risk factors and unfavorable social environment and provide early intervention to reduce the risk of preterm delivery.
