BERNARDI, Juliana Rombaldi et al. Estimation of energy and macronutrient intake at home and in the kindergarten programs in preschool children. J. Pediatr. (Rio J.) [online]. 2010, vol.86, n.1, pp.59-64. ISSN 0021-7557. http://dx.doi.org/10.1590/S0021-75572010000100011.
OBJECTIVE: To estimate the energy and macronutrient intake at home and at all-day in the kindergarten programs in children aged 2 to 6 and to investigate differences in consumption and intake between children at public and private kindergartens. METHODS: This was a cross-sectional study of 362 preschool children from Caxias do Sul, Brazil. Nutritional status was assessed in terms of weight to height ratios. Foods consumed in the kindergarten were evaluated by weighing the actual foods eaten by the children and home intakes were calculated from a food diary kept by parents or guardians. Statistical analyses were performed using the Mann-Whitney U test (p < 0.05). RESULTS: It was found that 28 children (7.7%) were overweight, 92 (25.4%) were at risk of becoming overweight and seven (1.9%) were classified as having wasting. Analysis of 24-hour nutritional intake demonstrated that 51.3% of the energy, 60.3% of the lipids and 51.6% of the proteins consumed by children were eaten at home, despite the children spending the whole day in the kindergarten programs. Preschool children at kindergartens ate greater quantities of energy (p = 0.001), carbohydrates (p < 0.001), and lipids (p = 0.04) than did children at public kindergartens, but their total daily intakes were similar, irrespective of which type of kindergarten program children attended. CONCLUSIONS: The findings suggest that these children eat proportionally more energy, proteins and lipids in their extra meals at home than they do in their daytime meals in the kindergarten programs. Despite the differences in intake between public and private kindergarten, daily intakes were similar.
