title: Effect of vitamin A supplementation on plasma and breast milk vitamin A levels in poorly nourished Gambian women.
abstract: Plasma and breast milk vitamin A and plasma carotenoids were measured in groups of pregnant and lactating women in two neighbouring rural Gambian villages. One of the groups (Keneba) received a 650 micrograms daily vitamin A supplement. During pregnancy, plasma retinol values were significantly (19 per cent) higher in the supplemented group. During lactation, breast milk values were significantly (23 per cent) higher in the supplemented group. Changes in plasma and breast milk vitamin A levels during the cycle of pregnancy and lactation and with season are also described, and the value of a combined index of plasma retinol and plasma carotenoids is illustrated. The significant effect of a prolonged low level vitamin A supplement to pregnant and lactating women has important implications for nutrition intervention programmes.
