The condition of schoolchildren's intake of calorie was investigated as one of the series of researches of the daily living schedule and diet of schoolchildren in the present city, which aimes at the search for the cause of their corpulence due to supernutrition. The object was 44 schoolchildren between 6 and 12 of age, divided into four groups, each of which was consisted of the boys or girls in the upper- or lower-class. Main results were as follows: 1. The ingested calories, compared with the required calories calculated out of the expended calories, were larger in all the objects, esp. was distinguished in the upper-class girls. 2. The ingested calories per a kilogram in body-weight were reduced in boys according as they were heavy in weight, while in girls this interrelation couldn't be gathered. 3. The expended calories per a kilogram were reduced according as girls as well as boys were heavy. 4. Girl's peculiarity described above in 2 and 3 are suspected as a cause for which girls grow over boys in terms of the physique.
The proportion of ingestion in schoolchildren of the three meals and snack in a day was investigated as the 2nd one of the series of researches of the daily living schedule and diet of schoolchildren in the present city. The object was the same 44 schoolchildren as the previous report, divided into four groups, each of which was consisted of the boys or girls in the upper- or lower-class. The view of this investigation was, by measuring their expended calories, to seek for the most adequate ration of the distribution of the three meals in a day. Results obtained were as follows: 1. As to the caloric intake and food intake there was little difference between boys and girls, but in the upper classes and lower ones it made difference. 2. Of the three meals school-feeding was in the highest proportion in the caloric and food intake. Larger quantities of snack was taken than is needed: quality is required to scrutinize further. 3. Calories were expended at the rate of 20% in the morning, 40% in the afternoon and 40% in the night. 4. Calories were taken in at the rate of 20% in breakfast, 50% in lunch and snack in the daytime and 30% in supper and snack in the night. 5. As to the distribution of the three meals: the intake of breakfast matters little: but the intake of lunch and snack in the daytime is too much: 30 to 34% is taken in school-feeding, in snack 16 to 20% is done. Snack in the daytime does, taking less intake of supper into consideration, produce a powerful effect on supper. The content of snack is needed to examine in detail.
