To examine the accuracy of several prediction equations for resting energy expenditure (REE) in children.
REE was measured in 113 prepubertal children (60 girls and 53 boys aged 3.9 to 7.8 years old, weighing 14.7 to 30.0 kg) using indirect calorimetry and compared with values estimated from the prediction equations of Altman and Dittmer, The Food and Agriculture Organization/World Health Organization/United Nations University (FAO/WHO/UNU), Maffeis et al, and Harris and Benedict.
Measured REE (MREE) was compared with predicted REE (PREE) by means of regression analysis. Prediction equations were considered accurate if the regression of MREE vs PREE was not significantly different from the line of identity (slope=1.0; intercept=0). Precision was assessed by the multiple correlation coefficient of the regression of MREE vs PREE.
MREE was 938+/-119 kcal/day, and PREE was 1,057+/-224 kcal/day for the Altman and Dittmer equations, 956+/-84 kcal/day for the FAO/WHO/UNU equations, 948+/-64 kcal/day for the equations of Maffeis et al, and 954+/-102 kcal/day for the Harris-Benedict equations. The regression of MREE vs PREE was significantly different from the line of identity for all prediction equations except the FAO/WHO/UNU equations (slope=0.96, P=.735; intercept=-15 kcal/day, P=.885 for girls and slope=1.08, P=.635; intercept=-62 kcal/day, P=.635 for boys). None of the equations was precise for MREE vs PREE (for all, R2<.6). For the FAO/WHO/UNU equations, less than half of the predictions were within +/-50 kcal/day but 99% were within 200 kcal/day.
Most prediction equations for REE in children do not accurately or precisely estimate REEs. The exception is the FAO/WHO/UNU equations, which are reasonably accurate and precise for practical purposes.
检验几种儿童静息能量消耗（REE）预测方程的准确性。
采用间接测热法对113名青春期前儿童（60名女孩和53名男孩，年龄3.9至7.8岁，体重14.7至30.0千克）的REE进行测量，并与根据奥特曼和迪特默、联合国粮食及农业组织/世界卫生组织/联合国大学（FAO/WHO/UNU）、马费斯等人以及哈里斯和本尼迪克特的预测方程估算的值进行比较。
通过回归分析将测量的REE（MREE）与预测的REE（PREE）进行比较。如果MREE与PREE的回归与恒等线（斜率 = 1.0；截距 = 0）无显著差异，则认为预测方程准确。通过MREE与PREE回归的多重相关系数评估精度。
奥特曼和迪特默方程的MREE为938±119千卡/天，PREE为1057±224千卡/天；FAO/WHO/UNU方程的MREE为956±84千卡/天；马费斯等人方程的MREE为948±64千卡/天；哈里斯 - 本尼迪克特方程的MREE为954±102千卡/天。除FAO/WHO/UNU方程外，所有预测方程的MREE与PREE的回归均与恒等线有显著差异（女孩的斜率 = 0.96，P = 0.735；截距 = -15千卡/天，P = 0.885；男孩的斜率 = 1.08，P = 0.635；截距 = -62千卡/天，P = 0.635）。对于MREE与PREE，没有一个方程是精确的（所有方程的R²<0.6）。对于FAO/WHO/UNU方程，不到一半的预测值在±50千卡/天范围内，但99%在200千卡/天范围内。
大多数儿童REE预测方程不能准确或精确地估计REE。例外的是FAO/WHO/UNU方程，出于实际目的，该方程具有合理的准确性和精确性。
