Prevalência de deficiência de vitamina A e fatores associados em pré-escolares de Teresina, Piauí, Brasil

Abstract: A deficiência de vitamina A constitui um problema de saúde pública no Nordeste brasileiro. O objetivo deste estudo foi determinar a prevalência da deficiência de vitamina A e os fatores associados em pré-escolares de Teresina, Piauí, Brasil. Os níveis de retinol sérico foram determinados por HPLC, e foram investigadas as características sócio-econômicas e demográficas de 631 crianças com idade de 36 a 83 meses.

“…18 The prevalence of 13.1% of the inadequate retinol levels (<0.70 µmol/L) found in the present study characterizes moderate public health problem in the studied population, according to the World Health Organization criteria. 2 This result was similar to another study conducted with preschool children in the state of Piaui, 19 confirming the data of a literature review on micronutrient deficiency in Brazilian children attending day care found an average prevalence of 12.5% of vitamin A deficiency. 20 On the other hand, some studies have found the prevalence of superior hypovitaminosis 9,10,21,22 as well as the National Survey on Demographics and Child and Woman Health (PNDS) with a prevalence of 17.4% higher in the Northeast (19.0%) and the Southeast (21.6%) of Brazil.…”

“…There was no association statistically significant differences found in the previous supplementation of vitamin A with inadequate levels of serum retinol according to another study, 21 however, other studies found benefits in the supplementation of vitamin A. 19,26 In this present study preschool children were assessed probably already received the preventive supplementation for a longer time, so the delay on the last dose could not interfere in the stocks of vitamin A. This study did not investigate the reason for high inadequacy in relation to the coverage of vitamin A supplementation, however many mothers reported lack of vitamin A in the health units.…”

“…Os estudos realizados nos últimos anos no Nordeste do Brasil indicam que a DVA se apresenta como um problema de Saúde Pública em crianças da região, apesar do decréscimo nas taxas de prevalência observado em estudos mais recentes 11,13 . No presente estudo, a prevalência de 9% de DVA, encontrada em crianças institucionalizadas de 36 a 83 meses de idade, concorda com dados do estudo recente conduzido em Pernambuco por Fernandes e col. 2005 11 que estimaram uma prevalência de 7% (IC96%:4,2 -10,2%) em pré-escolares de creches públicas da cidade de Recife.…”
