RESUMEN
The aim of this study was to apply methodological procedures to determine the prevalence of adequacy of Iron and vitamin C in children's diets. It was included 238 children aged 2 to 3 years enrolled in 2009 in 25 day care centers in the municipality of Rio de Janeiro. Dietary intake was assessed by weighing the food and food record. Assessing the prevalence of nutrient adequacy took into consideration the individual and the group. The best estimate of the needs of the individual is given by the estimated average requirement (EAR), since we do not know the true needs of the individual who is being evaluated. To estimate the need of the group method was used EAR as the cutoff. The prevalence of adequacy of iron and vitamin C in children's diets was 91.2 and 62.2%, respectively. All necessary to achieve the method EAR as the cutoff were used, but became unviable the adjustment of the observed consumption data to estimate the distribution of usual intake in this group. We conclude that the study of probability of adequacy of habitual diet in iron and vitamin C in the age group in question was only possible with the use of procedures for the individual.

O objetivo deste estudo foi aplicar procedimentos metodológicos para determinar a prevalência de adequação de ferro e vitamina C em dietas infantis. Foram incluídas na amostra 238 crianças de 2 e 3 anos matriculadas no ano de 2009 em 25 creches no município do Rio de Janeiro. O consumo alimentar foi avaliado por pesagem de alimentos e registro alimentar. Para avaliação da prevalência de adequação de um nutriente levou-se em consideração o indivíduo e o grupo. A melhor estimativa das necessidades do indivíduo é dada pela necessidade média estimada (EAR), já que não se conhece a necessidade verdadeira do indivíduo que se está avaliando. Para estimar a necessidade do grupo foi utilizado o método da EAR como ponto de corte. A prevalência de adequação de ferro e vitamina C nas dietas infantis para cada criança foi de 91,2 e 62,2%, respectivamente. Foram utilizadas todas as premissas necessárias à consecução do método da EAR como ponto de corte, porém tornou-se inviável o ajustamento dos dados de consumo observado para estimar a distribuição do consumo habitual neste grupo. Conclui-se que o estudo de probabilidade de adequação da dieta habitual em ferro e vitamina C no grupo etário em apreço só foi possível com a utilização dos procedimentos destinados ao indivíduo.
