Previous issue date: 2015-08-07 / Foram considerados os indicadores nutricionais, funcionais e bioqu?micos para determinar os intervalos de refer?ncia e o status de zinco s?rico em crian?as saud?veis do Nordeste brasileiro. Foram estudas 131 crian?as aparentemente saud?veis, 72 meninas e 59 meninos, entre 6-9 anos de idade. A avalia??o antropom?trica foi feita pelo IMC/idade; a avalia??o diet?tica por registro alimentar prospectivo de 3 dias e da avalia??o de par?metros bioqu?micos. As amostras de zinco s?rico foram analisadas em triplicada por meio da espectrofotometria de absor??o at?mica. Todos os indiv?duos eram eutr?ficos de acordo com a classifica??o de IMC/idade. Com rela??o ? avalia??o diet?tica, somente a ingest?o de fibras e c?lcio estavam abaixo das recomenda??es para idade e g?nero. Todos os par?metros bioqu?micos estavam de acordo com os par?metros de refer?ncia. Os intervalos de refer?ncia para a concentra??o de zinco s?rico foram: nos meninos de 0,70-1,14 ?g/mL; nas meninas de 0,73-1,17 ?g/mL; e na popula??o total de 0,72-1,15 ?g/mL. Este estudo apresenta intervalos de refer?ncia pedi?tricos para a concentra??o de zinco s?rico, que s?o ?teis para estabelecer o status de zinco na popula??o ou em grupos espec?ficos. / Objective: To determine the zinc status and reference intervals for serum zinc concentration considering dietary, functional, and biochemical indicators in healthy children in the Brazilian Northeast.
Methods: The study included 131 healthy children, 72 girls and 59 boys, between 6-9 years old. Anthropometric assessment was made by BMI/age; dietary assessment by prospective 3-day food register, and evaluation of total proteins was performed. Zinc in serum samples were analyzed in triplicate in the same assay flame using atomic absorption spectrophotometry.
Results: All subjects were eutrophic according to BMI/age classification. With respect to dietary assessment, only the intake of fiber and calcium were below the recommendations by age and gender. Biochemical parameters were all within the normal reference range. Reference intervals for basal serum zinc concentration 0.70-1.14 ?g/mL in boys, 0.73-1.17 ?g/mL in girls, and 0.72-1.15 ?g/mL in total population.
Conclusions: This study presents pediatric reference intervals for serum zinc concentration, which are useful to establish the zinc status in the population or in specific groups.
