To utilize obstetric risk factors and perinatal outcomes of pregnancies complicated by umbilical cord prolapse. Birth records of 76 cases with umbilical cord prolapse and 760 randomly selected controls were reviewed retrospectively. Statistical analysis was performed using logistic regression models. Prolapse of the umbilical cord complicated 0.32% (n = 76) of all deliveries included in the study (n = 23818). Multiparity was more common in patients with umbilical cord prolapse (88.2-58.3% , p< 0.0001). Umbilical cord prolapse occurred in breech presentation in 17 cases (22.4%) and in transverse presentation in 3 of the cases (9.2%). The occurrence of breech presentation among the control cases was 1.2% and of the transverse lie was 0.9%. Fetuses with umbilical cord prolapse had lower fetal weight; Particularly, fetal weight less than 2500 g was a significant risk factor (9.2-3.9%, p< 0.05). We also found that Premature Rupture Of Membranes (PORM) (OR = 0.92; 95%,CI = 0.81-0.99), and polyhydramnios (OR = 0.91; 95%, CI = 0.84-0.97) were risk factors for umbilical cord prolapse. The newborns that were delivered after umbilical cord prolapse graded lower Apgar scores less than 7 at 5 min (9.2-0.6%, p< 0.0001). Abnormal fetal presentation, multiparity, low birth weight, polyhydramnios and Premature Rupture Of Membranes(PORM), are risk factors for umbilical cord prolapse.
