dc.description.abstractTo evaluate vitamin A concentration in mature breast milk of nursing mothers aiming to meet the daily needs and the formation of liver reserve in pre-term (PT) and term infants (T) in comparison with the recommended intake for this nutrient in this group.We analyzed the retinol concentration in the milk of 120 nursing mothers (40 of PT infants and 80 of T infants) by collecting 10 mL of mature breast milk, held by a hand spray of one of the breasts 2 h after the last feeding in the morning. the cutoff points adopted for identification of vitamin A deficiency (VAD) and the liver reserve were < 1.05 and > 2.3 mu mol/L, respectively.The concentrations of retinol in the human milk of T infants were superior to concentrations in the milk of PT infants (1.87 + 0.81 > 1.38 + 0.67 mu mol/L, p < 0.0001). They were higher in T compared to PT (352.64 + 152.72 > 217.65 + 105.65 mu g, p < 0.0001), but both were below the recommendation. VAD was 20.0 % (T) and 27.5 % (PT). Only 40.0 % (T) and 22.5 % (PT) of the mothers had retinol concentrations in milk above 2.3 mmol/L.The milk of the nursing mothers studied did not have enough retinol to meet the daily needs and to form liver reserve in both groups, especially in PT newborns. This finding reinforces the idea that supplementation with massive doses of vitamin A in the immediate postpartum period can be used as a protective device of the infant against VAD.en
