Weight also was closely correlated with REE (R2 = 0.56): REE = 15.1 x weight + 371. Fat-free mass (FFM) was the best single predictor of REE (R2 = 0.64): REE = 19.7 x FFM + 413. The Harris-Benedict Equations derived in 1919 overestimated measured REE by 5% (p less than 0.01). Aunque la ecuación de Harris y Benedict (ver artículo anterior) se ha venido utilizando durante casi un siglo, estudios recientes han mostrado que en personas con sobrepeso u obesos la citada ecuación tiende a sobreestimar el consumo energético basal, en algunos casos por encima del 5. The inclusion of relative body weight and body-weight distribution did not significantly improve the predictive value of these equations. Simplification of this formula and separation by sex did not affect its predictive value: REE (males) = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) + 5 REE (females) = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) - 161. A new predictive equation for resting energy expenditure in healthy individuals. Macro calculator by Roy Harrington - Mifflin-St Jeor Equation Sedentary (Little or no Exercise) Lightly active (sports 1 3 days/ week) Moderately active (. Multiple-regression analyses were employed to drive relationships between REE and weight, height, and age for both men and women (R2 = 0.71): REE = 9.99 x weight + 6.25 x height - 4.92 x age + 166 x sex (males, 1 females, 0) - 161. Jeor equation was unbiased (95 confidence interval 26 to +8 kcal/day), the Livingston equation tended to underestimate true metabolic. Mifflin MD, St Jeor ST, Hill LA, Scott BJ, Daugherty SA, Koh YO (1990). Normal-weight (n = 264) and obese (n = 234) individuals were studied and REE was measured by indirect calorimetry. A predictive equation for resting energy expenditure (REE) was derived from data from 498 healthy subjects, including females (n = 247) and males (n = 251), aged 19-78 y (45 +/- 14 y, mean +/- SD).
