The institutional ethical committee has approved the study. The medical records of eligible cases were reviewed. To assess the risk factors of PPROM, the data of the cases with PPROM in 2016 were compared with the data of pregnant women who did not have PPROM and delivered at term.

In 2016, 252 pregnant women were diagnosed PPROM and data of 199 cases were compared with the data of 199 control cases. Mean latency period was 2 days and mean gestational age at birth was 34.7 weeks in PPROM group. Logistic regression analysis showed that diabetes mellitus, poor weight gain and history of previous preterm birth were the factors that significantly associated with PPROM, with adjusted odds ratio (OR) 3.22 (95% confidence interval [CI] 1.47\u20137.05), 2.58 (95% CI 1.63\u20134.07) and 8.81 (95% CI 2.81\u201328.69), respectively (<jats:italic>P<\/jats:italic> &lt; 0.05), while multiparity decreased the risk of PPROM (adjusted OR = 0.36, 95% CI 0.23\u20130.57) (<jats:italic>P<\/jats:italic> &lt; 0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The incidence of PPROM during 5\u2010year period was 2.93%.
