title: Vitamin D, vitamin A, maternal-perinatal considerations: old concepts, new insights, new questions.
abstract: Vitamins A and D are essential nutrients that play important roles in growth and development. Preterm and low birth weight infants have low levels of these nutrients and are at risk for developing detrimental health consequences associated with vitamin A and vitamin D deficiencies. Preliminary data suggest that vitamin A and D supplementation is needed to prevent deficiency. More work is needed to define optimal doses, timing, and modes of administration to ensure that an adequate supply of these vitamins is available to meet the critical needs during pregnancy and in high-risk neonates.
