The World Health Organization reported several equations for estimating the basal metabolic rate (BMR) in patients. One group is based on height and weight. The authors are from an FAO/WHO/UNU Expert Committee.
Patient selection: pediatric and adult patients
Output: BMR in kcal per 24 hour
Parameters:
(1) age in years
(2) gender
(3) weight in kilograms
