The aim of this study was to determine simple predictive factors of the resting energy expenditure (REE) in children. Two groups, A (n = 14) and B (n = 23), were defined by their weight-for-height index, less than 90% and greater than 90%, respectively. Anthropometrically assessed lean body mass (LBM), 24-h urinary creatinine, and REE were measured. From multiple-regression analysis, the best-fitting equation for calculating REE (REE = 54.4 LBM (kg) + 0.095 creatinine (mmol/kg) + 4.7) was highly significant (r = 0.987, p less than 0.0001). Although the regressions of REE on weight were significantly different between the two groups, the equations using LBM or 24-h urinary creatinine did not discriminate between them. These findings suggest that an equation based on LBM or 24-h urinary creatinine excretion could be a more accurate estimate of REE than are conventional methods based on weight or height, and it may be applicable to diverse nutritional states.
