Objective to establish the value of the resting energy expenditure (REE) in healthy newborns and evaluate relative factors of REE.
目的检测我国健康新生儿静息能量消耗值(REE)，评估不同因素对其的影响。
Methods:Methods including time-motion, body weight balance, activity index and REE(resting energy expenditure) calculation were used.
方法：采用“生活观察法”、“体重平衡法”、“生活活动指数法”、“REE推算法”。
The resting energy expenditure (REE)of newborn infants is influenced by many factors and energy metabolism in the newborn infants varies considerably.
新生儿静息能量消耗受多种因素影响，而且新生儿的能量代谢变化率很大。
Resting energy expenditure can be measured with the use of indirect calorimetry or more conveniently estimated with the use of standard predictive equations.
静息时的能量消耗可采用间接测热法测量，或更方便地采用标准预测方程进行估计。
Physical activity is defined as any bodily movement produced by the contraction of skeletal muscles that result in a substantial increase over resting energy expenditure.
体力活动是指由骨骼肌收缩所引起的、导致在静止的能量消耗的基础上能量消耗增加的任何身体运动。
The Thermic Effect of food is defined as: the increment in energy expenditure above resting metabolic rate due to the cost of processing food for storage and use.
食物热效应的定义是：机体摄入食物过程中，机体能量代谢比基础代谢增高的部分。
