Acceptable prediction of REE (90110% adequacy) was found in 47% of the patients by using the Harris and Benedicts equation and in only 37% by using the Schofields equation. 3060. The IOM physical activity recommendations were based on measurements of total energy expenditure (doubly labeled water) and predicted REE (in the case of children) or measured REE (values for adults).

Triceps, subscapular, and suprailiac skinfolds were measured on the right side of the body to the nearest 0.5 mm with the use of a Lange Skinfold Caliper (Beta Technology Inc, Cambridge, MD; respective equations are given in reference 34). Conclusions: WebThis approach is limited by the choice of equation (Schofield et al 1985) used to calculate basal metabolic rate, and by lack of easily interpretable activity tables for children. There is no doubt that huge databases suffer from several methodologic shortcomings. An assessment of energy needs is a necessary component in the development and evaluation of a nutrition care plan. Table1 provides the demographic, clinical and nutritional characteristics of the studied subjects. Comparisons of REE predicted by the equations with REE measured by indirect calorimetry are presented in Figure1. None of the authors had any conflicts of interest. < 3 years. The determination of resting energy expenditure (REE) is the primary step for estimating the energy requirement of an individual.

Because most of the authors were working in the area of obesity research, there was a high prevalence of overweight and obese subjects. Dietitians should be aware of the limitations of the REE equations when prescribing energy intake for CKD patients. Energy metabolism. Nelson KM, Weinsier R, Long CL, Schutz Y.

FFM, fat-free mass; FM, fat mass; REE, resting energy expenditure. Four prediction equations were identified as the most commonly used in clinical practice (Harris-Benedict, Mifflin-St Jeor, Owen, and World Health Organization/Food and Agriculture Organization/United Nations University [WHO/FAO/UNU]).

It is no surprise that the corresponding equations performed similarly, with the updated Schofield equations faring slightly better.

J Am Diet Assoc. Methods: stream Are metabolic adaptations to weight changes an artefact? Significant deviations were still observed for underweight and normal-weight subjects. WHO prediction equations systematically overestimated REE at low REE values but underestimated REE at high REE values. A total of 281 CKD patients (124 non-dialysis, 99 haemodialysis and 58 peritoneal dialysis) were included in the present study. Regarding biological determinants of REE, FFM was found to be it's major determinant (see Results). Mller MJ, Bosy-Westphal A, Kutzner D, Heller M.

For the adults, data from 180 subjects whose REE was measured with a closed system are depicted in the insets. [BMI percentiles for children and adolescents considering several German samples. Unable to load your collection due to an error, Unable to load your delegates due to an error. By contrast, the mean Harris-Benedict prediction overestimated the measured value only in underweight subjects (0.54 0.84 MJ/d; P < 0.001), whereas in normal-weight, overweight, and obese subjects, the mean REE predicted according to the Harris-Benedict formula was not significantly different from the measured value (differences of 0.02 0.88, 0.00 0.78, and 0.05 0.95 MJ/d in normal-weight, overweight, and obese subjects, respectively). These data should be based on stringent inclusion criteria and be capable of being used mathematically to derive suitable predictors and to generate new prediction formulas for REE (19). The most traditionally used prediction equations overestimated the REE of CKD patients, and the errors were minimized in the presence of comorbidities. Therefore, a systematic review of the literature was undertaken to document the accuracy of predictive equations preliminary to deciding on the imperative to measure metabolic rate.

441. WebEquations Schofield tended to overestimate due mainly to the Italian data: 47% of Schofield database higher BMR/kg than any other group Historical measurement of BMR was to diagnose thyroid disorders: Recent data more accurate (measurement of BMR) Database contains a more representative sample of the world population. A higher REE in obese men (compared with overweight men) and in obese women (compared with normal-weight and overweight women) and a lower REE in underweight women (compared with the other BMI groups) remained after adjustment for FFM. Background: Reference standards for resting energy expenditure (REE) are widely used. Physical characteristics of the study population 1. Accuracy of four resting metabolic rate prediction equations: effects of sex, body mass index, age, and race/ethnicity. The metabolic rate can be measured or estimated by equations, but estimation is by far the more common method. Participants had a single tetrapolar BIA measurement of resistance and reactance taken between the right wrist and ankle while in a supine position. 700. Limitations in the Schofield data are also seen in the FAO/WHO/UNU, since the Schofield equations were formulated as extensions of the FAO/WHO/UNU data. In conclusion, REE prediction by WHO formulas systematically over- and underestimates REE and is inadequate for use in underweight subjects. The whole study population of 2528 subjects is characterized in Table 2. Flack KD, Siders WA, Johnson L, Roemmich JN. All subjects were white, nonpregnant, and nonlactating. Resting energy expenditure (REE) prediction equations for adults based on data from subpopulation 1 and from BMI (in kg/m2) subgroups of subpopulation 11. MJM was responsible for the study design. Resting energy expenditure (REE) plotted against body weight or fat-free mass (FFM) in children and adolescents and in adults (total n = 2348). 17. Dietary reference intakes: energy, carbohydrate, fiber, fat, fatty acids, cholesterol, protein and amino acids. Of these equations, the Mifflin-St Jeor equation was the most reliable, predicting RMR within 10% of measured in more nonobese and obese individuals than any other equation, and it also had the narrowest error range. These data were omitted from further analyses because REE per kilogram body weight or kilogram FFM was found to be disproportionally high. By contrast, adjustment of REE for FFM plus FM showed higher REE in normal-weight men and women than in overweight or obese men and women or in underweight women. Design: The study was a cross-sectional and retrospective analysis of data on REE and body composition obtained from 2528 subjects aged 591 y in 7 different centers between 1985 and 2002. In 180 adults (78 females and 102 males), REE was measured with the use of a closed system. Nutrients. Schofield- Men 18-29 yrs BMR= (74 x This simplified equation predicted measured REE in the validation dataset with much higher accuracy (narrow limits of agreement) compared to the Schofield equation. Thirteen percent of the patients were taking calcitriol. WHO formulas are widely used to predict REE. This figure can then be used to design a dietary regime that places the subject in calorie deficit or surplus, depending on whether Physical activity and fat-free mass during growth and in later life. Accessibility In fact, the 2 prediction formulas have been reported to overpredict but also to underestimate measured REE in more recent studies (615). WebSchofield Equation for Females. According to the WHO criteria (33), a high prevalence of overweight and obesity was found in the whole study population. Before Magnesium: extracellular, intracellular or total magnesium status? *P < 0.001 Harris and Benedict > indirect calorimetry; **P < 0.001 Schofield > Harris and Benedict and indirect calorimetry.

2023 Feb 27;13:1058187. doi: 10.3389/fonc.2023.1058187. Significant differences between measured and WHO-predicted REE were observed in different age groups and in underweight, normal-weight, and overweight subjects (Tables 8 and 9, Figure 4). MeSH REE prediction formulas for specific body mass index groups reduced the deviations.
