Abstract
This study sought to identify the association between the concentration of hemoglobin and socio-environmental, maternal, biological-nutritional and health condition characteristics in preschool children; as well as the serum concentrations of zinc and retinol. It involved a cross-sectional study with 335 individuals, a representative sample of children enrolled in child day care centers in the city of Campina Grande, Paraíba. In the 294 children studied, the adjusted model showed lower concentrations of hemoglobin when the house was not made of bricks; there was no sewerage system; no public garbage collection; no treatment of drinking water; maternal difficulties for reading, writing and making calculations; age between 9 - 24 months; weight/age < - 2 score Z and health problems in the last 15 days, as well as in cases of lower serum concentrations of zinc and retinol. The multicausality of lower hemoglobin levels included socio-environmental conditions and child-maternal characteristics that reinforce the importance of measures that prioritize the younger children of mothers with lower education levels and prejudiced in weight, health and nutritional status of other important micronutrients for growth.
