Accuracy of a Portable Multisensor Body Monitor for Predicting Resting Energy Expenditure in Older People: A Comparison with Indirect Calorimetry

Abstract

The SWA provides a reliable estimate of REE in healthy older subjects and has the advantage of easy handling. The 20-min recording time, which was recommended by the manufacturer, can be applied. However, the SWA overestimates REE in this group, possibly due to age-related changes in skin conductance and thermoregulation, both being measured by sensors of the SWA armband. This requires improving the SWA by developing better fitting algorithms for predicting REE in older people.
