Comparación del aporte de vitamina A en leche materna y alimentos complementarios en la dieta de lactantes de 6 meses de Jujuy y Buenos Aires / 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

El objetivo fue comparar el patrón alimentario en poblaciones en dos contextos socioculturales diferentes, con énfasis en el aporte de vitamina A de la leche materna y los alimentos complementarios consumidos con mayor frecuencia. Se realizaron encuestas de alimentación del niño al 6º mes a madres lactantes en Jujuy (n= 44) y en Buenos Aires (n= 95). El retinol lácteo se determinó por cromatografía líquida; en los alimentos, se estimaron valor calórico y vitamina A. En Jujuy y Buenos Aires, el 75,6% y el 64,5% de los lactantes recibían alimentos complementarios al 6º mes; más del 50% los habían incorporado antes. El retinol lácteo varió entre 0,02 y 1,19 µg/mL y 0,09 y 1,94 µg/mL para Jujuy y Buenos Aires. Se observaron valores < 0,30 µg/mL, indicativos de déficit, en 67,4% y 26,1% de leches, respectivamente. Los alimentos habituales aportarían suficiente vitamina A en Buenos Aires e insuficiente en Jujuy.

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

Patrón alimentario de una comunidad aborigen de la patagonia Argentina / Pattern fo food consuption of south patagonian aboriginal groups in Argentina

Objetivo: Caracterizar el patrón alimentario y determinar el aporte nutricional de grupos de alimentos, hidratos de carbono, proteínas de origen animal y vegetal, lípidos, energía, calcio, hierro y vitamina C. Material y Método: Encuesta de recordatorio de 24 horas a 14 de las 40 familias que residían en Colonia Pastoril Cushamen, durante Junio de 2002. Resultados: La mediana del valor energético total de la dieta por persona y por día fue de 1260 kilocalorías (IC95 por ciento: 1056,2- 1747,4). Del total de proteínas (mediana: 46,1 g), el porcentaje de origen animal fue importante (mediana: 67,2 por ciento; IC95 por ciento: 45,6- 73,6). Se destaca una ingesta de hierro favorable respecto a otras regiones del país. El consumo de calcio y vitamina C fue extremadamente bajo. Conclusión: En base a trabajos previos, se evidencia un deterioro de la diversificación de la dieta, a pesar de las estrategias que procuran conservar el patrón alimentario propio.
