NUTRITIONAL STATUS, ANEMIA AND ASSOCIATED FACTORS IN CHILDREN AND ADOLESCENTS ATTENDING PUBLIC SCHOOLS IN THE NORTHEAST OF BRAZIL: A BEFORE AND AFTER INTERVENTION WITH IRON SUPPLEMENTATION
Keywords:
Iron deficiency anemia, Nutritional status, Obesity, Children, AdolescentsAbstract
OBJECTIVE: To assess nutritional status and factors associated with iron deficiency in children and adolescents, before and after intervention with iron amino chelate.
METHODS: In this community-based, double-blind, randomized controlled trial, we assessed children aged 3-14 years. Children were cluster randomized to receive either iron supplemented food (intervention), or the same food without supplement (control).
RESULTS: Most participants presented adequate height-for-age and BMI-for-age values. No association between nutritional status and the iron deficiency anemia (IDA), independently of the allocation group, was observed. After intervention, there was a reduction of anemic children in both groups; however there was a more significant reduction in the intervention group when compared to the control group, p<0.0001. There was also a greater reduction in the number anemic individuals with low height-for-age in the intervention group when compared to control, p=0,028. Those who remained anemic during the study were more likely to present short stature at the end, with no association or difference between the two groups.
CONCLUSIONS: It was concluded that in the supplementation group that those who remained anemic during the trial were more likely to continue anemic after intervention, with shorter stature; with no other association or difference between groups.
