Aims: Preterm labor is the most common cause of mortality among neonates. The risk of spontaneous preterm labor is increased due to various maternal factors. Therefore, the objective of this study was to investigate the maternal factors involved in preterm labor.
Materials & Methods: This cross-sectional study as a descriptive-analytic and retrospective study was conducted on 2432 women referred to Sarem women’s hospital in 2013. The patients' data including demographic information and risk factors for preterm labor were collected by a researcher-made-questionnaire. The data were analyzed by Mann-Whitney U, Fisher's exact and Chi square tests using SPSS 22 software.
Findings: The prevalence of preterm labor was found as 237 (9.75%). The maternal factors including body mass index (BMI), maternal age (more than 35 years), history of thyroid disease, intrauterine fetal death (IUFD), premature rupture of membranes (PROM), preeclampsia, parity, two or multiple pregnancies and abnormal volume of amniotic fluid showed significant correlation  with the occurrence of spontaneous preterm labor (P <0.05). However, the other factors including hypertension history before pregnancy, history of abortion, history of diabetes and ectopic pregnancy did not show statistically significant correlation with preterm labor (P>0.05).
Conclusion: Maternal factors including BMI, maternal age, thyroid disease, IUFD, PROM, preeclampsia, parity, two or multiple pregnancies and abnormal volume of amniotic fluid can influence the occurrence of spontaneous preterm labor.
