Research Abstract	The aim of this study was to determine total energy expenditure (TEE), resting energy expenditure (REE), and physical activity energy expenditure (PAEE) in Japanese infant. Subjects were 30 boys and 30 girls (age : 68.1 +/- 8.0 months, BMI : 15.4 +/-1.2kg/m2). TEE was measured in free-living conditions using doubly labeled water method. PAEE was determined from TEE and REE. Simultaneously, anthropometry and body composition by bioelectrical impedance analysis were measured. In present study, no gender differences in TEE, REE, and PAEE were observed. Additionally, they were no significant correlations with body composition. This study showed that DLW-derived TEE and PAEE were 1374.5+/-223.8kcal/day (TEE/Wt : 74.3+/-10.4kcal/kg/day) and 353.7+/-194.3(PAEE/Wt : 19.1+/-10.5kcal/kg/day), respectively.
