Micronutrient Fortification at Child-Care Centers Reduces Anemia in Young Children.

The aim of this study was to evaluate the effectiveness of NutriSUS micronutrient fortification, in infants aged 12-36 months, for the prophylaxis and treatment of iron deficiency anemia. In this cluster-randomized clinical trial study, we evaluated infants aged 12-36 months. Length of intervention was 12 weeks. Children were cluster randomized to either NutriSUS micronutrient fortification (Group A) or control (Group B). Primary outcome variables were change in hemoglobin concentration and anemia prevalence. Two biochemical evaluations were performed to determine hemoglobin concentrations: before and after intervention. This study was conducted in eight child-care centers located within the urban perimeter of the municipality of Sobral, Ceará, in the northeast of Brazil. For Group A, baseline mean hemoglobin concentration was 11.4 ± 1.01 g/dL; after intervention it was 11.9 ± 0.90 g/dL (p = .006); 15 of 20 participants who were anemic at baseline had normal Hb levels after intervention. Number needed to treat = 2. In group B, mean baseline hemoglobin was 11.9 ± 0.89 g/dL; after intervention it was 12.2 ± 0.92 g/dL (p = .58); 4 of 5 participants who were anemic at baseline remained anemic after intervention. In our study, NutriSUS micronutrient fortification provided a beneficial effect on Hb values, reducing the prevalence of anemia. However, further studies are necessary to confirm the effectiveness of this intervention in populations on a larger scale.
