Formulas and Characteristics of 6 Commonly Used RMR Prediction Equations for Women
| Prediction Equation | Formula | Characteristics of Population Included in the Development of Equation |
|---|---|---|
| Harris-Benedict12 | kcal/d = 655.0955 + 9.5634 × weight (kg) + 1.8496 × height (cm) – 4.6756 × age (y) | n = 103 Predominantly normal weight women Weight (mean) = 56.4 kga Weight (range) = 35.6-94.1 kg Age range = 15-74 y No specific racial/ethnic information provided |
| Robertson and Reid13 | kcal/d = BSA (m2)b × 24 × (age-specific value) | n = 1323 Female nurses in training at Middlesex Hospital, England, medical students, and other hospital staff, children attending welfare clinics and on tonsillectomy waiting lists, and members of the public who responded to newspaper advertisements Age range = 3-74 y (included men aged up to 80 y) No specific weight information provided No specific racial/ethnic information provided |
| Cunningham14 | kcal/d = 500 + 22 × lean body massc | n = 223 Original participants of the Harris-Benedict study,12 excluding 16 male athletes Weight information was not published Weight (mean)d = 59.8 kg Weight (range)d = 33.2-94.1 kg Age ranged = 15-74 y No specific racial/ethnic information provided Not a gender-specific equation |
| FAO/WHO/UNU15 | 18-30 y: kcal/d = 13.3 × weight (kg) + 334 × height (m) + 35 30-60 y: kcal/d = 8.7 × weight (kg) – 25 × height (m) + 865 >60 y: kcal/d = 9.2 × weight (kg) + 637 × height (m) – 302 |
Developed using data from the Schofield study16,17 n = 11 000 (included men, women, and children) Included healthy adults of varying weights, heights, and ages Multiethnic cohort; included a large number of Italian participants |
| Owen et al18 7.18 × weight (kg) | Nonathletese: kcal/d = 795 + Athletes: kcal/d = 50.4 + 21.1 × weight (kg) | n = 44 (included 8 athletes) Participants represent a wide range of weight categories: underweight (n = 1), normal weight (n = 23), overweight (n = 4), obese (n = 10), and extremely obese (n = 6); excluding athletes: underweight (n = 1), normal weight (n = 15), overweight (n = 4), obese (n = 10), and extremely obese (n = 6) Weight (mean) = 74.9 and 79 kgf (excluding athletes) Weight (range) = 43-143 kg Age range = 18-65 y No specific racial/ethnic information provided |
| Mifflin-St. Jeor19 | kcal/d = 9.99 × weight (kg) + 6.25 × height (cm) – 4.92 × age (y) – 161 | n = 247 Healthy working-class women Participants represented normal weight (n = 135) and obese (n = 112) categories Weight (mean) = 78.9 ± 16.7 kg Weight (range) = 46-120 kg Age range = 20-76 y No specific racial/ethnic information provided |
Abbreviations: BSA, body surface area; FAO/WHO/UNU, Food and Agricultural Organization/World Health Organization/United Nations University; RMR, resting metabolic rate.
Calculated from the original Harris-Benedict study (Table D).12
BSA estimated from stature and body weight by the DuBois and DuBois formula20 : Area (cm2) = Weight (kg)0.425 × Height (cm)0.725 × 71.84.
In the present study, lean body mass was determined by dual-energy x-ray absorptiometric analysis.
Calculated from the original Harris-Benedict study tables (Tables C and D).12
In the present study, the Owen et al equation for nonathletes was used.
Calculated from the Owen et al clinical measurements and body composition table.18
