RESUMO

Childhood and adolescence are considered periods that involve a series of changes in which some of them are worth enlightening: the physical growth and development that requires a higher intake of energy and nutrients. It is important that these subjects have a balanced food intake concerning energy and nutrients to reassure that the changes such as in body composition and sexual maturation are guaranteed. One of the most important goals of this work is the assessesment of the nutritional status, the energy and nutrients intake, and the macronutrients present in diets of a sample of 1325 students, enrolled in 20 public schools in 10 Brazilian states. The data on the students food intake were obtained using the 24-hour Recall Method. To the nutritional analyses the software Virtual Nutri was used. It was identified among the main findings an average of energy intake (1503.4 kcal) which was considered below the recommended allowance for the group. When the distribution of the students according to the participation of the macronutrients in the total energy value of the diet was analyzed, it was observed that most of them (55%) has inadequate diets, being the worst situations among students of the Northeast Region (Parnaíba and Brasileira) and the North Region (Abaetetuba and Tailândia). The opposite was found among the students from Joinville-SC (71,3% of the group had diets classified as adequate). The analyses of the nutritional status found no prevalence of low weight among the students in the study. Most of them (around 92.6%) were classified as eutrophic and an expected rate (5%) was identified as overweight. Nonetheless among the students from Joinville (14.7%) and Ponte Serrada (16.3%) the results related to overweightness (percentages practically 3 times higher) distinguished by the superiority over the others. Regarding the consumption of minerals, it is surprisingly the low intake of calcium: most of them hadn’t had 50% of the recommended allowance. In relation to the average intake of vitamins the situation can be classified as more regular, except when the reduced intake of folacin and pantotenic acid is considered. The average content of fibers in the diets of all the students is cause of worries especially when the recommended daily allowance (25 to 38g): the highest intake was observed in students from Paraiba (14.3g) and the lowest was identified in students from Joinville. There are no doubts that the group of children and adolescents, especially the ones who attend public schools deserve close attention from the health and educational institutions concerning to food comsuption.
