There are almost no data on the calorie requirement for infant and child. The standard value of the calorie requirement for the nutrition of infant and child now in use in Japan is also merely a rough presumed value. In order to establish the standard value of the calorie requirement firmly, the author has determined basal metabolism and the maintenance metabolism at the time of waking and at the time of sleep of infant and child of a nursery by a open system calorimetric method employing a specific respiration sack. Further, the author determined the quantity of motion and the total consumed calorie of the above infants and children. Roughly the following results were thus obtained. 1. When the consumed calorie determined continuously was compared with that calculated from the results of the determination of the maintenance metabolism, exercise metabolism and the time distribution of daily life, almost no difference was shown between them. In both cases, the value was approximately 80 Cal. per 1 kg body weight for infants more than 2 months of age. 2. The calorie requirement for the infants under investigation, which is consisting of the consumed calorie plus the calorie converted from the increment in the body weight, was found roughly approximate to the standard value of the nutritional calorie requirement published by the World Health Organization of the United Nations. 3. There was as large a discrepancy as 5-20% between the calorie up-take and calorie requirement for the infants under investigation. This discrepancy was particularly large in the cases of infants of 1-5 months of age, at which they were vigorously growing. Though the above discrepancy may be due to the loss accompanied with growth metabolism, but it was considered mainly due to markedly unfavorable rate of digestion and absorption in the case of artificial nutrition. 4. When the calorie requirement for the vigorously growing infants under invetigation was estimated by adding 10% wasted calorie, it was found somehow corresponding to the value which has recently been published by the Calorie Committee of the Food and Agriculture Organization. However, when it was converted for an infant or child having the Japanese standard body weight, it became as a small value as 5-20 Cal. due to smalll increment in the body weight. 5. When the calorie requirement for an infant having Japanese standard body weight was calculated taking the active nutrition for the growth and the functional adaptation of the digestive system into consideration, it became roughly as follows per 1 kg body weight per day. 0- 1 month 80 Cal. 1-3 months 120 Cal. 4-9 months 105 Cal. 10-12 months 95 Cal. 1- 2 years 95 Cal.
