Evaluation of maternal risk factors for preterm delivery in Fatemieh Hospital of Hamadan, Iran, 2019: A case-control study.

Abstract

Background:The present study aimed to evaluate maternal risk factors of preterm delivery in Fatemieh Hospital in Hamadan, Iran, 2019.Methods:In this case-control study, 7,478 hospital files of live-born neonates and their mothers in Hamadan Fatemieh Hospital in 2019 were examined. According to statistical estimates, 261 preterm deliveries and 736 term deliveries were studied. Information files of neonates and mothers were used to complete the study questionnaire. The data were compared in two separate groups and logistic regression was performed to estimate the crude relationship between demographic and clinical characteristics of term and preterm delivery.Results:The mean age of women was 27.89 ± 6.48 years. Analysis of data revealed that academic education (OR: 2.02, P = 0.014), age group 25-34 years (OR: 1.5, P = 0.016), age of 35 years and above (OR: 1.66, P = 0.018), previous history of preterm delivery (OR: 5.3, P < 0.001), history of abortion (OR: 1.67, P = 0.004), history of surgery (OR: 1.54, P = 0.007), history of infertility (P = 0.016), and a history of cesarean (OR: 2.11, P < 0.001) were potentially associated with a higher odds of preterm delivery (P < 0.2).Conclusion:Based on the results, it is important to identify potential risk factors of preterm delivery in mothers and corrective interventions in strengthening consultation and education of pregnant women during pregnancy. Such a measure helps select the type of delivery and strengthen prenatal care in identifying mothers in high-risk groups and performing timely interventions.
