Abstract
To evaluate the validity of the currently available regression equations for the calculation of resting metabolic rate (RMR), we compared the measured RMR with those calculated from 4 equations in obese (0) (26 boys, 20 girls; age mean+-SE: 13.3+-0.3 yrs; weight: 72.6+-5.1 kg; height: 162+-1.5 cm; body fat: 38.1+-0.5 %) and nonobese (C) (21 boys, 19 girls; age: 12.8+-0.3 yrs; weight: 41.5+-1.5 kg; height: 153+-1.9 cm; body fat: 19.3+-0.9 %) adolescents. RMR was measured after an overnight fast by means of open circuit indirect calorimeter. The measured RMR (0:1682+-45.4, C:1186+-32.3 kcal/day) were significantly ( p< 0.01) lower than those calculated from the Harris-Benedict equation (0:1882+-48.6, C:1302+-29.3 kcal/day), Mayo nomogram (0:2047+-42.2, C:1446+-31 kcal/day and the equation of FAO/WHO/UNU (0:1920+-60, C:1285+-41.9 kcal/day). The most accurate estimate of RMR was given by the Cunningham equation (0:1685+-40.2. C: 1226+-24.2 kcal/day). The above results confirm the urgent need of new standards for estimation of energy requirements.
