Abstract

Background: Placental abruption is one of the most common causes of bleeding during pregnancy. Multiple factors are known to be associated with increase of risk of placental abruption such as alcohol, cocaine use and cigarette smoking. The objective of this study was to identify risk factors for placental abruption in an Iranian women population. Materials and Methods: In a retrospective case-control study birth records included 78 cases with placental abruption and 780 randomly selected controls were investigated. Statistical analysis for comparing the studied risk factors between groups was performed using Pearson's Chisquare test along with presenting relevant odds ratio (OR). Results: From 7301 deliveries included in the study, 78 (1%) was complicated placental abruption. Women aged 35 or more likely for experiencing (OR = 3.650, 95% confidence interval [CL] = 1.57-6.83) and those who had a previous cesarean section (OR = 2.65, 95% CL = 3.91- 33.41) were in higher risk for placental abruption ([50 cases] 64% vs. [28 cases] 36% P < 0.01). Conclusion: The results indicate that among the placental abruption is one of the most common causes of bleeding during the pregnancy and one of the major obstetrical emergency.
