Abstract
The physical status and food intake were examined for the healthy 61 boys and 33 girls (6-15years old) living under the institutional care in Osaka City in August, 1974. Urine and feces of the subjects were also collected for the nitrogen balance study.
Positive nitrogen balance was observed except for one subject who showed almost zero balance. The correlation between nitrogen intake and nitrogen accumulation per day or body weight was significantly positive in boys, but the correlation was observed only between nitrogen intake and nitrogen accumulation per body weight in girls. Age or body weight of children showed significant inverse correlation with nitrogen accumulation per body weight regardless of sex.
Protein intake per body weight differed between boys and girls of 12 to 15 years of age; less in girls. From the fact that the physical development was well in all the subjects, it seemed that their protein intake was adequate.
