Luhrmann et al developed several equations for estimating the resting metabolic rate (RMR) of an older adult. The authors are from the University of Giessen in Germany.
Patient selection: adult >= 60 years of age without thyroid disease
Output: RMR in kJ per day (1 kcal = 4.184 kJ; 1 kJ = 0.239 kcal)
Parameters:
(1) body weight in kilograms
(2) age in years
(3) sex (0 if female, 1 if male)
The equation which accounted for the largest variance (R^2 74%) is:
