Results: In this descriptive-analytical study, 400 pregnant women were studied. Two hundred of pregnant women had preterm premature rupture of membranes and 200 of pregnant women did not have such condistion and were normal. The mean age of pregnant women was 27.4±5.4 years old and the mean gestational age of pregnant women was 34.1±2.1 weeks. The mean parity of pregnant women was 2.3±1.4. Risk factors such as maternal age (P=0.011), number of pregnancies (P=0.035), maternal education (P=0.018), history of preterm premature rupture of membranes (P=0.046), history of preterm delivery (P=0.019), trauma (P=0.037) and pregnancy care (P=0.037) affected preterm premature rupture of membranes.
Conclusion: The results of this study showed that maternal age, number of pregnancies, maternal education, and history of preterm premature rupture of membranes, history of preterm delivery, trauma, and prenatal care are risk factors for PROM. Therefore, by educating pregnant mothers about these risk factors, the incidence and complications of preterm premature rupture of membranes can be reduced.
