摘　　要：目的用活动记录辅助加速度仪测量人体日常活动的能量消耗，为监测个体总能量消耗（TEE）提供简便易行的方法。方法采用气体代谢法标定加速仪不同活动强度记录所对应的能量消耗；41名受试者连续佩戴加速度仪7d，同时记录每日活动，间接估算每日总能量消耗。结果加速仪测量TEE，男性（9761±866）kJ／d[（2332±207）kcal／d，休力活动水平（PAL）1．46±0．11]，女性（7526±879）kJ／d[（1798±210）kcal／d，PAL1．43±0．09]；加速仪结合活动记录的测量结果为，男性（10573±804）kJ／d[（2526±192）kcal／d，PAL1．58±0．10]，女性（8191±737）kJ／d[（1957±176）kcal／d，PAL1．56±0．08]。结论加速度仪配合活动记录所得TEE值在既往报道的范围之内，可以作为监测个体TEE和体力活动水平变化的简便方法。Objective Using accelerometer and physical activity logs to evaluate daily energy expenditure, as to providing a simple and convenient method to survey the total energy expenditure（TEE）. Methods The different activity intensities recorded by accelerometer were distinguished into a certain different energy expenditure value by gas metabolism method. Forty-one participants wore the accelerometer for 7 days continuously and completed physical activity logs everyday at the same time. The total energy expenditure was evaluated by these methods. Results Total energy expenditure evaluated by accelerometer was （9761 ±866）kJ/d[ （2332 ±207） kcal/d,PAL 1.46±0.11] for male and （7526±879 ）kJ/d [ （1798 ± 210）kcal/d ,PAL 1.43 ± 0. 09 ] for female; whereas combining accelerometer and physical activity logs data showed that the total energy expenditure was （ 10 573 ± 804） kJ/d [ （2526 ± 192） kcal/d, PAL 1.58±0.10] for male, and 8191 ± 737 kJ/d [（1957 ± 176）kcal/d, PAL 1.56 ± 0.08] for female. Conclusions Using accelerometer and physical activity logs to evaluate the total energy expenditure might be consistent with the existing data, so this method might be used to survey the individual energy expenditure and physical activity levels.
