Schofield et al reported several equations for estimating the basal metabolic rate (BMR) in patients. One group is based on weight. The authors are from the University of Cambridge and the FAO/WHO/UNU Expert Committee.
Patient selection: pediatric and adult patients
Output: BMR in megaJoules per 24 hour
Parameters:
(1) age in years
(2) gender
(3) weight in kilograms
