Objectives: To determine the prevalence of anemia in pregnant women and characterize its effect on neonatal outcome in Northeast India. Patients and methods: Four hundred and seventy mothers and their newborn infants during a one month period were included. The association between maternal hemoglobin (Hb) at delivery and neonatal outcomes were determined. Results: Anemia (Hb < 110 g/L) was present in 421 (89.6%) mothers with 35 (8.3%) having severe anemia(Hb < 70 g/L). After adjusting for maternal and neonatal variables, each 10 g/L decrease in maternal Hb was associated with 0.18 week decrease in gestational length (p=0.003) and 21 g decrease in birth weight (p=0.093). Severe maternal anemia was associated with 0.63week (95% CI, 0.03-1.23week) shorter gestation, 481 g (95% CI, 305-658 g) lower birth weight and 89% increased risk of small-for-gestation (OR 1.89, 95% CI, 1.25-2.86)in the offspring, compared with those born to mothers without anemia (p < 0.001). Conclusion: Maternal anemia was highly prevalentin this population. Lower gestational age and birth weight, and increased risk of small-for-gestation were associated with maternal anemia, especially when maternal Hb was <80 g/L. Maternal anemia needs urgent attention to improve neonatal outcome in this population.
