Nutrients intake and anemia in children of day nurseries of Goiânia
Introduction: The high prevalence of anemia, which is a serious public healthproblem, together with an early and in appropriate introduction of food for children,shows a close relationship between feeding practices and the presence of anemia.Objectives: To compare anemia among anemic and non-anemic children enrolled inmunicipal day nurseries of Goiânia, the socioeconomic and demographiccharacteristics, nutritional status, distribution of the consumption of macronutrientsand the intake of micronutrients (calcium, iron and vitamin C), for Dietary ReferenceIntakes; evaluate and compare the ingestion of total iron, heme and non-heme ironand the bioavailable iron in the diets of anemic and non-anemic children from 12 to24 months and compare the bioavailable iron according to algorithms developed byMonsen et al. and FAO / WHO. Methods: Observational study of cross-sectionalanalysis with children from 6 to 24 months in Goiânia-Goiás, in the years of 2005 and2006. Investigations of socioeconomic, demographic and food (direct food weighingand 24 hour dietary recall) were applied for 2 days and the anthropometric evaluationand the dosage of hemoglobin were done. The diagnosis of anemia was determinedby the level of hemoglobin less than 11 g / dL. Results: 89 children were studied.The prevalence of anemia was 53.9%. It was observed an statistically significantdifference between anemic and non-anemic children as for per capita income. Theproportion of macronutrients in the diets of the evaluated groups was appropriate andthere was no difference statistically significant. Among the anemic children (n = 47),the prevalence of inadequacy was 12.8% for iron and 8.5% for vitamin C, whereas inthe non-anemic ones (n = 41), the prevalence of inadequacy for iron and vitamin Cwas: 14.6% and 7.3%, respectively. The average intake of calcium was 50% abovethe recommendations in both groups. By the criterion of the World HealthOrganization, it was realized an anthropometric evaluation in three moments and theanemic had greater z-score according to the weight / length than non-anemic in the 2and 3 moments (p = 0.015 p = 0.006) respectively . The average consumption of totaliron, non-heme and bioavailable iron were low in the groups studied, showing nostatistically significant difference. There was an intense positive correlation betweenthe methodologies used to evaluate the iron bioavailable (r = 0.91 r = 0.84) for nonanemicand anemic children, respectively. Conclusion: There was a statisticallydifference between per capita income and anemia. It was observed a greater z-scorefor the index weight / length in the anemic children. There was no statisticallydifference between the two groups in relation to the consumption of calcium, iron andvitamin C, however there was a significant prevalence of inadequacy of iron andvitamin C, besides a high intake of calcium in the diet. There was a low totalconsumption of iron, heme and non-heme and bioavailable iron that reinforces theimportance of the knowledge of food consumption of children, as well as the adoptionof measures that ensure the supply of food sources of iron and food promoters ofbioavailability of this micronutrient.
