Original Communications Predicting Energy Expenditure in Extremely Obese Women

ABSTRACT. Background: The most common clinical method for resting energy expenditure (REE) assessment is prediction equations. The purpose of this study was to elucidate which prediction equation is most accurate for REE assessment in extremely obese women. Methods: Fourteen extremely obese women (mean SD body mass index: 49.8 6.2 kg/m2; age: 49 10 years) were measured for height and weight and REE via indirect calorimetry (IC) by a metabolic cart system. Pre-dicted REE was evaluated by several equations, including Harris-Benedict with actual body weight, Harris-Benedict with several adjustments to body weight, Cunningham, Mifflin-St Jeor, Owen, World Health Organization (WHO), and Bern-stein equations. Accuracy was determined by mean difference data (IC REE equation REE; Student’s paired t-test), corre-lation coefficients, and agreement between methods by Bland
