![]() ![]() ![]() The Mifflin-St Jeor equation was most accurate method for REE assessment in extremely obese women. A further difficulty is that many of the suggested stress factors were developed at a time when it was common to adjust the body weight used in the Harris. The Harris-Benedict with actual body weight and WHO equations were less accurate on individual terms, with 29% and 42% of the predicted REE values, respectively, falling outside +/-10% of IC REE. The healthy equation most often used is the Harris-Benedict equation, making prediction methods difficult to update to one of the more contemporary equations such as MifflinSt Jeor. According to the individual data, the Mifflin-St Jeor was most accurate (14% outside +/-10% IC REE). The mean predicted REE values by all other equations were different from the IC REE values (p <. The Mifflin-St Jeor, Harris-Benedict with actual body weight, and the WHO equations were the most accurate in terms of mean predicted REE. Accuracy was also evaluated on an individual basis, defined by the percentage of individuals within +/-10% of IC REE. In 2005 The American Dietetic Association (ADA) compared the BMR formulas of Harris-Benedict, Mifflin-St. Accuracy was determined by mean difference data (IC REE - equation REE Student's paired t-test), correlation coefficients, and agreement between methods by Bland-Altman plots. In 1990 the Mifflin-St Jeor formula was introduced. ![]() Predicted REE was evaluated by several equations, including Harris-Benedict with actual body weight, Harris-Benedict with several adjustments to body weight, Cunningham, Mifflin-St Jeor, Owen, World Health Organization (WHO), and Bernstein equations. The purpose of this study was to elucidate which prediction equation is most accurate for REE assessment in extremely obese women.įourteen extremely obese women (mean +/- SD body mass index: 49.8 +/- 6.2 kg/m(2) age: 49 +/- 10 years) were measured for height and weight and REE via indirect calorimetry (IC) by a metabolic cart system. The most common clinical method for resting energy expenditure (REE) assessment is prediction equations. ![]()
