Deficiência de vitamina A em pré-escolares da cidade do Recife, Nordeste do Brasil

the purpose of the study was to evaluate the extent of vitamin a deficiency (vad) among preschool children in the city of recife, northeast brazil. the sample comprised 344 children of both sexes, 24 to 60 months old, in 18 public day care centres in the city of recife, in 2007. the nutritional status of vitamin a was assessed by biochemical (serum retinol) and dietetic (vitamin a rich-food consumption) indicators and the pondo-stature status through anthropometric indicators weight-for-age, height-for-age and weight-for-height. the prevalence of hyporetinolemia (<-2 scores -z) in preschool children were 2.5% for the indicator weight-for-age, 8.6% for height-for-age and 1.5% for weight-for-height. the research findings point out to the importance of institutionalization for the appropriate nutritional status of children and maintenance of adequate reserves of vitamin a. however, more studies are needed focusing on non-institutionalized preschool, or children living outside the privileged environment of public day care centres.
