Total energy expenditure was measured in a cohort of 33 normal, full term infants at 12 weeks of age using the doubly labelled water technique. These data were related to Quetelet's index and the sum of the triceps and subscapular skinfold measurements at 9 months and 2 years of age. Correlation coefficients were used to determine the relationship between total energy expenditure and later indices of body composition. Total energy expenditure was expressed as kcal/kg per day; kcal/kg0.5 per day (in order to negate the effect of body weight) and kcal/kg fat free mass per day (in order to take into account body composition). Using this approach there was no relationship between the level of total energy expenditure at 12 weeks of age and later indices of body fatness. The highest correlation coefficient being 0.09 (n = 33, P greater than 0.10). These findings are contrary to recent reports that a reduced total energy expenditure is related to the development of obesity in certain selected groups of individuals.
采用双标记水技术对33名足月正常婴儿在12周龄时的总能量消耗进行了测量。这些数据与9个月和2岁时的克托莱指数以及肱三头肌和肩胛下皮褶测量值之和相关。使用相关系数来确定总能量消耗与后期身体成分指标之间的关系。总能量消耗表示为每天千卡/千克；每天千卡/千克0.5（为了消除体重的影响）和每天千卡/千克去脂体重（为了考虑身体成分）。采用这种方法，12周龄时的总能量消耗水平与后期身体脂肪指标之间没有关系。最高相关系数为0.09（n = 33，P大于0.10）。这些发现与最近的报道相反，那些报道称在某些特定个体群体中，总能量消耗降低与肥胖的发展有关。
