OBJECTIVE:To estimate the isolated and combined prevalence of anemia, vitamin A deficiency and zinc deficiency in pre-school children, as well as the distribution of isolated deficiencies according to gender, age and prior supplementation with vitamin A.METHODS:Cross-sectional study with pre-school children in the state of Paraíba, Brazil. Analysis of the average concentrations of hemoglobin, serum retinol and serum zinc, according to gender, age and previous vitamin A supplementation of children were carried out as well as the risk of simultaneous occurrence of micronutrient deficiencies in the presence of these deficiencies.RESULTS:The prevalence of anemia, vitamin A deficiency and zinc deficiency were 15.4%, 23.3% and 13.8%, respectively. The anemia was significantly associated with age (p<0.01). Children previously supplemented by vitamin A had higher serum retinol concentrations than children without supplements, an effect that was not observed for concentrations of hemoglobin or serum zinc. The prevalence of anemia associated with vitamin A deficiency was 5.8%, with the chance of vitamin A deficiency and anemia coexist 2.21 times (95%CI=1.03-4.84) higher in the case of vitamin A deficiency or anemia rather than in the absence of these conditions.CONCLUSION:The high prevalence of micronutrient deficiencies which are important in child growth, as well as the coexistence of nutritional deficiencies, point out the need to strengthen nutrition intervention strategies that consider this issue.
