Selected Pregnancy Variables in Women with Placenta Previa

The aim of this study was to investigate risk factors and perinatal outcomes of pregnancies complicated by placenta previa. Birth records of 93 cases with placenta previa and 940 randomly selected controls were reviewed retrospectively. Statistical analysis was performed using Pearson`s Chi-Square method. Placenta previa complicated 0.73% (n = 93) of all deliveries included in the study (n = 12834). Multiparity was more common in patients with placenta previa (78.5%, p<0.001). Placenta previa occurred in male infants in 62 cases (76.6%). Fetuses with placenta previa had lower fetal weight ; particularly, fetal weight less than 2500 g was a significant (40.9.%, p<0.0001). We also found that previous abortion (OR = 0.7; 95% CI = 0.57-0.83), previous placenta previa (OR = 5.17; 95%, CI = 5.61-7.62) and previous cesarean section (OR = 11.5; 95% CI = 3.91-33.41) were risk factors for placenta previa. The newborns that were delivered after placenta previa graded lower Apgar scores less than 7 at 5 min (24.7%, p<0.0001). Multiparity, previous placenta previa, previous abortion and previous cesarean section are risk factors for placenta previa.
