Objective: To evaluate the vitamin A status in serum and colostrum of postpartum women with different socioeconomic status, comparing the colostrum retinol supply with the vitamin A requirement of the newborn. Methods: Cross-sectional study conducted with 424 postpartum women. Vitamin A maternal dietary intake was estimated using a food frequency questionnaire. Colostrum and serum retinol levels were measured by high performance liquid chromatography (HPLC). Serum retinol concentrations <20

Results: The mean maternal vitamin A intake during pregnancy was 872.2 ± 639.2 gRAE/day in low-income women and 1169.2 ± 695.2 gRAE/day for high-income women (p < 0.005). The prevalence of vitamin A deficiency was 6.9% (n = 18) in the low-income group and 3.7% (n = 6) in the high-income group. The estimated mean retinol intake by infants of the highand low-income mothers were 343.3 gRAE/day (85.8% AI) and 427.2 gRAE/day (106.8% AI), respectively. ଝ Please cite this article as: Gurgel CS, Grilo EC, Lira LQ, Assunção DG, Oliveira PG, Melo LR, et al.
