Objectives:
To analyze the maternal and perinatal outcome in varying degrees of anemia.
Methods:
A total of 447 pregnant women were divided into group I (Hb>11 g%, n=123 women), group II (Hb 9-10.9 g%, n=214 women), group III (Hb 7-8.9 g%, n=79 women) group IV (Hb<7 g%, n=31 women). Their maternal and perinatal outcome, mode of delivery, duration of labor and postpartum complications were noted and analyzed using multiple logistic regression to calculate odds ratios (95% CI) for duration of labor, mode of delivery and low birth babies. Chi square or Fisher's exact test was employed for difference in proportions and Student's t-test for testing difference between means.
Results:
Mean age (27+/-4.25 years) and number of women with parity >3 were highest in group IV. The patients with Hb<8.9 g% had a 4-6-fold higher risk of prolonged labor compared to Hb>11 g%. The odds ratios for abnormal delivery (cesarean and operative vaginal deliveries) showed a 4.8-fold higher risk (95% CI 1.82, 12.7) in patients with Hb
Conclusions:
Mild anemia fared best in maternal and perinatal outcome. Severe anemia was associated with increased low birth weight babies, induction rates, operative deliveries and prolonged labor.
