Retinol and Betacarotene Status in Mother-Infant Dyads and Associations between Them.

Background/aims: Assessing the diet and biochemical indicators of vitamin A deficiency (VAD) in high-risk populations is crucial in cases where this deficiency is mainly caused by chronically inadequate intake. This study aimed to determine the retinol and betacarotene status in mother-infant dyads, and to evaluate the associations between them.

Methods: Umbilical cord serum, maternal serum, and colostrum were collected from 134 healthy mothers living in a risk region for VAD.
