Antenatal vitamin A supplementation increases birth weight and decreases anemia among infants born to human immunodeficiency virus-infected women in Malawi

Abstract

Vitamin A is essential for immunity and growth. A controlled clinical that involved 697 human immunodeficiency virus (HIV)-infected pregnant women was conducted to determine whether vitamin A prevents anemia, low birth weight, growth failure, HIV transmission, and mortality. Women received daily doses of iron and folate, either alone or combined with vitamin A (3 mg retinol equivalent), from 18-28 weeks' gestation until delivery. In the vitamin A and control groups, respectively, the mean (± SE) birth weights were 2895 ± 31 g and 2805 ± 32 g (P = .05), the proportions of low-birth-weight infants were 14.0% and 21.1% (P = .03), the proportions of anemic infants at 6 weeks postpartum were 23.4% and 40.6% (P
