The Harris-Benedict equation produced the largest mean difference from measured RMR and the greatest number of participants whose predicted RMR exceeded 10% of measured RMR.
For a female population whose RMR may be higher, the Mifflin equation (optimal range, 1280 to 1595 kcal/day) or the Harris-Benedict equation (optimal range, 1345 to 1630 kcal/day) may be used.
34 Standard error of 131 132 estimate (kcal/day) Number of subjects for 35 35 whom predicted and measured RMR differed by [greater than or equal to] 10% SD = standard deviation (a) Mean [+ or -] SD (b) Harris-Benedict equation (3): 65 5.
8,15) The Harris-Benedict equation (Table 2) is thought to overestimate requirements in healthy people, perhaps by 5% in men or 15% in women.
An advantage of the Mifflin-St Jeor equation (Table 3) is that it is very simple and easy to remember; however, like the Harris-Benedict equation, it requires values for both weight and height.
The studies that derived these injury factors have most commonly used the Harris-Benedict equation, and consequently it has been argued that the factors are not valid to use with other equations.
