Patient selection: obese Caucasian children and adolescents from 7 to 18 years of age
Paramters:
(1) gender (female 0, male 1)
(2) body weight in kilograms
(3) height in meters
(4) Tanner pubertal stage (from 1 to 5)
(5) fat-free mass in kilograms
(6) fat mass in kilograms
BMR in MJ/day =
= (0.044 * (body weight)) + (2.836 * (height)) – (0.148 * (Tanner stage)) + (0.781 * (points for gender)) – 0.551
BMR in MJ/day =
= (0.082 * (fat free mass)) + (0.037 * (fat mass)) – (0.125 * (Tanner stage)) + (0.706 * (points for gender)) + 2.528
Performance:
• Both equations have an adjusted R-squared of about 0.70.
• The root mean squared error (RMSE) for the first equation is 0.954 and for the second 0.943.
