Abstract:A razão nitrogênio ureico/creatinina (N u/c) foi medida em indivíduos de ambos os sexos nos grupos de 3 a 10 anos, 11 a 15 anos e acima de 15 anos de idade, em uma amostra das populações das comunidades de Vila de Icapara, Pontal do Ribeira e diaristas de Iguape, localizadas no litoral sul de São Paulo, no Vale do Ribeira. Foi calculada a adequação do consumo de proteínas entre as famílias, através dos resultados de um inquérito alimentar feito pelo método das pesagens. Partiu-se da hipótese de que haveria mai… Show more
“…The present data agrees with that found among 6-10 year old Dutch children, while many Africans excrete much less urea N/creatinine, and figures as low as 2 gN/g have been reported from New Guinea. Comparisons between urea N/creatinine results and dietary analysis have been made (Martins, 1972). By taking a cut off point at 5 gN/g, there was considerable agreement between feeding unsatisfactory diets and the urea N/creatinine.…”
A comparison of the excretion of urinary metabolites was made between seven years old schoolgirls from the upper and lower socioeconomic strata. The hydroxyproline index was lower in the children from the lower income groups, thus agreeing with anthropometric data which indicated that the children probably had lower growth rates than the children of professional people. No difference in protein status was found, but the results of urinary sulfate and nitrogen indicated that the amino acid composition of the dietary protein was a function of socioeconomic status. Children of professional people excreted four times as much riboflavin as those in the lower socioeconomic strata. Professionals' children also excreted significantly more vitamin C. No significant differences were found for thiamin or N-methyl nicotinamide. In the light of these findings, certain recommendations are made for improving school meal feeding in Iran.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
