摘要

This rapid systematic review aimed to evaluate the diagnostic accuracy (concurrent validity, predictive ability, reliability) of indirect calorimetry (IC) for measuring resting energy expenditure (REE) in adults with overweight or obesity. PubMed and Web of Science searched for studies measuring REE by IC in adults with overweight or obesity and reported primary outcomes: concurrent validity, predictive ability, or reliability. N = 22 studies were included that evaluated n = 10 IC devices. A handheld IC device was reported to have poor concurrent validity and poor reliability. Standard desktop IC devices were reported to have inconsistent concurrent validity, inconsistent predictive ability for weight loss, and good to excellent reliability. Whole-room IC devices were reported to have excellent reliability. Further research is needed.
