Hipovitaminose A em crianças de áreas rurais do semi-árido baiano

Abstract: Objetivou-se avaliar a distribuição e a magnitude da deficiência de vitamina A e o consumo dietético de 161 crianças de 6 a 72 meses de idade, de áreas rurais do Município de Cansanção-Bahia, Brasil. Os níveis de retinol sérico foram medidos pelo método espectrofotométrico (Bessey-Lowry modificado por Araújo e Flores, 1978). A média do retinol sérico distribuiuse homogeneamente entre as diferentes faixas etárias. Níveis inadequados de retinol sérico (deficiente <10,0 mg/dl e baixos <20,0 mg/dl) foram detectado… Show more

“…These eating habits, together with early weaning and reduced consumption of food sources of carotenoids, may explain the insuffi cient retinol serum levels in children in lower age groups. 12 In this study, no statistical differences with regards to VAD and the children's gender were found, a result similar to those observed in other studies. 5,12,22 According to the WHO, c differences in rates of VAD prevalence related to sex are attributed to cultural differences in eating habits and are not consistent with the existence of a physiological factor in this association.…”

“…e High prevalence of VAD have been found in representative samples of children under 5 in other states in the Northeast of Brazil, such as Pernambuco (22.3%), b Alagoas (44.8%), 21 Bahia (44.7%) 12 and Sergipe (32.1%). 9 According to the National Demographic and Health Survey 17.4% of children have VAD, with the highest rates of prevalence found in the Northeast (19.0%) and Southeast (21.6%) of the country.…”

“…Nossos resultados corroboram com outros estudos realizados no Nordeste do Brasil, que 15 , investigando a hipovitaminose A em crianças de 6 a 72 meses de idade na zona rural do Município de Cansanção, e Santos et al 16 , avaliando esta carência em pré-escolares de nove municípios do Estado, observaram, respectivamente, 44,7% e 54,7% de crianças com valores de retinol sérico < 0,70 µmol/L. Estas cifras refletem a situação no iní-cio da implantação do Programa de Combate à Deficiência de Vitamina A, podendo ter havido alteração a partir de então.…”
