Estimation of Free-Living Energy Expenditure using Doubly Labelled Water Method in Japanese Children

本研究的目的是确定日本婴儿的总能量消耗（TEE），静息能量消耗（REE）和体力活动能量消耗（PAEE）。受试者为30名男孩和30名女孩（年龄：68.1 ± 8.0个月，BMI：15.4 ± 1.2kg/m2）。在自由生活条件下，使用双标记水法测量TEE。PAEE由TEE和REE测定。同时，人体测量和身体成分的生物电阻抗分析。在本研究中，没有观察到TEE，REE和PAEE的性别差异。此外，它们与身体组成没有显著的相关性。本研究显示，DLW衍生的TEE和PAEE分别为1374.5+/-223.8 kcal/d（TEE/Wt：74.3+/-10.4 kcal/kg/d）和353.7+/-194.3（PAEE/Wt：19.1+/-10.5 kcal/kg/d）。

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.
