BACKGROUND: Preterm birth (PTB) is one of the most important factors that increase the risk ofchronic diseases and postpartum death in infants. The aim of this study was to determine the maternalfactors that affect the birth of preterm infants in the city of Bandar Abbas.MATERIALS AND METHODS: This is a case–control study that was performed on 400 preterminfants. Sampling was done by a simple method, and information was gathered by interviewing themothers and their medical records. Data were collected by SPSS software version 16. To comparerisk factors in the two groups, conditional logistic regression was used, and P < 0.05 was consideredstatistically significant.RESULTS: Results showed that factors such as type of delivery (odds ratio [OR] = 3.584, 95%confidence interval [CI]: 1.981–6.485), preeclampsia (OR = 2.688, 95% CI: 1.164–6.207), historyof PTB (OR = 4.171, 95% CI: 1.483–11.728), premature rupture of membranes (OR = 3.273,95% CI: 1.745–6.137), care during prenatal (OR = 0.334, 95% CI: 0.159–0.701), placentalabruption (OR = 3.209, 95% CI: 1.209–8.519), placenta previa (OR = 9.333, 95% CI: 2.086–41.770),and cervical insufficiency (OR = 11, 95% CI: 1.381–87.641) were independent risk factors of preterminfant birth.CONCLUSIONS: The PTB risk is higher for women with cervical insufficiency, history of placentaprevia, and history of preterm. Early recognition and management of these high‑risk conditions amongpregnant women may lead to a reduction in PTB rates.
