Predictive Equations Overestimate Resting Metabolic Rate in Survivors of Chronic Stroke.

ABSTRACT:

Objective

To measure resting metabolic rate (RMR) in survivors of chronic (>3 months prior) stroke (mean ± SEM age, 61±7.5 years) and to compare to predicted RMR using predictive equations in adults without stroke.

Design

Cross-sectional study.

Setting

Hospital.

Participants

Survivors of stroke (N=71).

Intervention

Not applicable.

Main outcome measures

RMR was measured by indirect calorimetry. Participants underwent a total body dual-energy x-ray absorptiometry scan and treadmill test for peak oxygen consumption (V̇o₂peak). RMR was calculated using 9 established equations.

Results

RMR measured (1552±319 kcal/d) was significantly lower than 9 predicted RMR values (all P<.001), with the best being McArdle-Katch (1652±233 kcal/d), L
