Resting energy expenditure in overweight and obese adults: Agreement between indirect calorimetry and predictive formulas

Abstract

This retrospective chart review of 100 overweight and obese white adults enrolled in an ambulatory care weight management program determined the limits of agreement between resting energy expenditure using the MedGem and 5 predictive equations. Data were analyzed using SPSS version 13.0. Alpha was set at .05. Limits of agreement were considered a bias of ± 150 cal and a precision of ±200 cal. Overall, no equation had acceptable bias or precision. However, 4 equations specific for age and gender had acceptable bias and precision for females. An accurate predictive formula for use in the overweight and obese adults is needed. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.
