MARIATH, Aline Brandão; GIACHINI, Rubia Mara; LAUDA, Laíz Guedes  and  GRILLO, Luciane Peter. Iron status and serum retinol levels among children and adolescents attended by a Family Health Strategy team in Itajaí, Santa Catarina State. Ciênc. saúde coletiva [online]. 2010, vol.15, n.2, pp.509-516. ISSN 1413-8123.

The objective of this article is to determine prevalence of iron and vitamin A deficiencies among children and adolescents attended by a Family Health Strategy team in Itajaí, Santa Catarina State, and to assess relations between iron status and serum retinol. A nutritional census of the families was carried out. Socioeconomic and demographic data were collected. Hemoglobin concentration, hematocrite, serum iron and retinal were determined. Thirty-one out of the 156 enrolled families participated in the study. Only 39.1% of the children and 62.0% of the adolescents had their blood samples collected. Mean per capita income was 1.68±1.00 minimum wages. None of the parents was illiterate and most families (80.6%) owned their homes. All homes had public sewage and water supply, and 87.1% were made of brickwork. Iron deficiency was diagnosed in 16.7% of the children and 19.3% of the adolescents. Only one child had vitamin A deficiency. Significant correlations were found between serum iron and retinol among children, and among adolescents between serum retinol and hemoglobin concentration and hematocrite. We found mild prevalences of iron and vitamin A deficiencies, possibly due to the socioeconomic and demographic characteristics.
