Abstract

Resting energy expenditure (REE) was measured by a Deltatrac (DT) metabolic cart and a MedGem (MG) handheld indirect calorimetry device in 14 extremely obese women. DT and MG REE measures were compared by Student's paired t test, correlation, and Bland-Altman plots. MG accuracy was also evaluated in comparison to DT by individual data inspection. DT and MG REE values were different on the basis of mean data. MG REE values were outside ±10% of DT REE in 6 of 14 subjects. It may be concluded from these data that the MG device may be unacceptable for clinical measurement of REE in this population.
