GRECO, Carola Beatriz et al. Comparison of vitamin A intake from breast milk and from complementary foods in the diet of six-month old infants in Jujuy and Buenos Aires. Arch. argent. pediatr. [online]. 2014, vol.112, n.5, pp.439-442. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2014.439.

The objective of this study was to compare the dietary pattern of two socio-culturally different populations, focusing on the vitamin A intake from breast milk and from the most commonly consumed complementary foods. Dietary surveys on six-month old infant feeding were administered to breastfeeding mothers in Jujuy (n= 44) and Buenos Aires (n= 95).For milk, the level of retinol was determined by liquid chromatography; for foods, calorie and vitamin A values were estimated. In Jujuy and Buenos Aires, 75.6% and 64.5% of infants were receiving complementary foods at six months old, and more than 50% had started earlier. Milk retinol ranged from 0.02 to 1.19 μg/ mL and from 0.09 to 1.94 μg/mL in mothers in Jujuy and Buenos Aires, respectively.Values <0.30 μg/mL, indicative of vitamin A deficiency, were observed in 67.4% and 26.1% of milk samples, respectively. Usually consumed foods may provide sufficient vitamin A for Buenos Aires participants, but insufficient for those in Jujuy.
