Thus, the use of total body weight by the prediction equations could be a potential source of overestimation of REE in these particular patients. Search for other works by this author on: Institute of Nutrition, Rio de Janeiro State University, REE was measured by indirect calorimetry using an open circuit ventilated computerized metabolic system (Vmax series 29n; SensorMedics Corp; Yorba Linda, CA, USA). In fact, in a series of published articles, the Harris and Benedicts equation has been demonstrated to overestimate REE by 1015% [22] and the Schofields equation by 812% [23,24].

Clinical outcomes of surgical treatment for end-stage ankle osteoarthritis in patients aged?=?75years: a multicenter, retrospective study.

Nineteen (20%) measurements were >110% above the age-appropriate Schofield-predicted equation, and 30 measurements (32%) were <90% below that predicted by Schofield.

sharing sensitive information, make sure youre on a federal Most authors used manufacturer's equations, which differed from each other, changed over time, and are partly unknown. WHO formulas are widely used to predict REE. Haemodialysis patients were dialysed for 4h thrice a week, and the predominant vascular access was arteriovenous fistula (92% of the patients). Indirect calorimetry is among the methods that most accurately measure the REE.

The database includes 2528 subjects with a wide age range.

eCollection 2023. In a subset of 2066 participants, body composition was assessed by either bioelectical impedance analysis (BIA; n = 1813 subjects) or skinfold-thickness measurements (n = 250 subjects). Previous reports, based on calorimetric methods, indicate reduced REE in non-dialysed CKD patients [6,7] and a normal to increased REE among dialysed patients [811] when compared with healthy subjects. Resting energy expenditure (REE) plotted against body weight or fat-free mass (FFM) in children and adolescents and in adults (total n = 2348).

P < 0.001 (Wilcoxon's signed-ranks test). WHO prediction equations systematically overestimated REE at low REE values but underestimated REE at high REE values. CKD patients were older, had higher serum concentrations of glucose and C-reactive protein, and had reduced body fat and energy intake in comparison with the healthy control. W=weight in kg; H=height in cm. <<

Pullicino E, Copperstone C, Luzi L, McNeill G, Elia M. Black AE, Coward WA, Cole TJ, Prentice AM. Methods. To find a simple method able to predict accurately the REE of CKD patients would be of relevant importance for the routine care of these patients. Serum creatinine, urea and glucose were determined by a standard autoanalyser. WebSchofield Equation for Females.

This number increased to 71% with the further inclusion of FM, age, and sex (Table 7).

Body weight was measured to the nearest 0.1 kg and standing height to the nearest 0.5 cm while the subject wore underwear and no shoes. The major finding of our study is that the widely used REE prediction equations are not adequate for a population living in a modern, affluent society in Germany. Regarding biological determinants of REE, FFM was found to be it's major determinant (see Results). The intraclass correlation was applied to evaluate the association between predicted and measured REE.

The WHO reference population also included a substantial number of subjects with a BMI < 17. Significantly different from M (Mann-Whitney U test): P < 0.05. Disclaimer. Careers. Of the entire group, 89% was taking diuretics and/or antihypertensive medications, and 33% was using -blockers.

Accessibility Results. The results from the Harris and Benedicts equation [36.9 (34.939.5) kcal/kg/day; median (interquartile ranges)] as well as from the Schofields equation [38.4 (36.041.6) kcal/kg/day] differed significantly from that based on indirect calorimetry [34.3 (31.438.2) kcal/kg/day; P < 0.001]. A biometric study of basal metabolism in man. Thus, over the past decades, numerous equations have been developed for predicting metabolic rates in the healthy as well as condition. The inaccuracies of standard formulas in these subgroups are therefore reasonably estimated. The different sex and age groups differed significantly in REE (Table 5 and data not shown). In the control group, the correlations between measured and predicted REE were similar (Harris and Benedict r = 0.65; P < 0.001 and Schofield r = 0.62; P < 0.001). According to the WHO criteria (33), a high prevalence of overweight and obesity was found in the whole study population.

These shortcomings are due in part to the heterogeneity of the reference study populations, methodologic drawbacks, and the variability of REE. Indirect calorimetry and blood sample collection were performed after a 12-h fasting.

J Sci Med Sport. REE was obtained by using indirect calorimetry with different ventilated hood systems, mouthpiece measurements, or a metabolic chamber (seeTable 1 for the description of the individual measurement procedure, technical details about instrumentation, and its calibration; references 2431).

Mean (SD) resting energy expenditure (REE), REE adjusted for fat-free mass (FFM), and REE adjusted for FFM and fat mass (FM) in underweight (n = 98 F, 9 M), normal-weight (n = 551 F, 375 M), overweight (n = 313 F, 220 M), and obese (n = 345 F, 194 M) women () and men (). There were no significant differences between the subgroups in any of the measured variables (Mann-Whitney U test). However, in agreement with the present study, the errors of both equations were relatively large. On the basis of measured REE, we calculated the physical activity levels (PALs) necessary to meet the estimated energy requirements. None declared.

Flack KD, Siders WA, Johnson L, Roemmich JN. Vinken AG, Bathalon GP, Sawaya AL, Dallal GE, Tucker KL, Roberts SB. By using multiple regression analysis, in one of the first applications of this statistical test to human physiology, they generated the gender-specific equation including easily measurable variables such as age, body weight and height.

Two prediction formulas including weight, sex, and age or fat-free mass, fat mass, sex, and age, respectively, were generated in a subpopulation and cross-validated in another subpopulation. By contrast, BMI groupspecific REE prediction equations reached a higher accuracy in these underweight subgroups than in the other subgroups.

By contrast, a lower ratio of REE to body mass (or FFM) is observed in overweight and obese subjects (20, 37, 38).

Nutritional Considerations in Celiac Disease and Non-Celiac Gluten/Wheat Sensitivity. Predictions below or above the limits were defined as underestimation or overestimation, respectively. BMI was calculated with weight (kg) and height (m) measurements. 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. Adjustments for FM were performed accordingly.

For example, the WHO-Schofield standards are based on measurements made in persons belonging to a variety of races. These numbers are 5.8% higher than the respective PALs derived from the DACH estimates (ie, 1.491.73). Multivariate regression analysis explained up to 75% of the variance in REE.

4 0 obj The database should consist of data obtained with the use of accurate and up-to-date indirect calorimetric methods (eg, excluding results obtained with the use of closed systems). Mean (SD) differences between measured resting energy expenditure (REEm) and REE predicted according to World Health Organization (WHO) formulas (REEWHO) for underweight (n = 98 F, 9 M), normal-weight (n = 551 F, 375 M), overweight (n =313 F, 220 M), and obese (n = 345 F, 194 M) women () and men (). Energy metabolism. However, whether these formulas adequately address REE in subjects living in modern, affluent societies is unclear. >>

Hypermetabolism, is it real?

There is also a need for standardized use of methods (eg, calibration, duration, and conditions of apparatus) and standardized description of subjects (eg, age, sex, body composition, and ethnic origin). This simplified equation predicted measured REE in the validation dataset with much higher accuracy (narrow limits of agreement) compared to the Schofield equation. Epub 2008 Oct 23.

The oxygen and carbon dioxide sensors were calibrated before each REE measurement with the use of mixed reference gases of known composition.

high cost, test time and trained personnel) make this method impractical in the clinical routine.

Commonwealth Bureau of Animal Nutrition Communication No. Supported by Deutsche Forschungsgemeinschaft (DFG M 8-1). 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.

Bethesda, MD 20894, Web Policies This is true for measurements of REE as well as for assessment of body composition. All subjects were healthy (defined as the absence of a clinical condition) except for 97 adults who were underweight (BMI < 18.5), with a mean (SD) BMI of 16.2 1.6 (range: 12.418.4). Objective: The aim of the present study was to investigate the application of the World Health Organization (WHO) equations from 1985 in healthy subjects living in a modern, affluent society in Germany and to generate a new formula for predicting REE. The recent population goals for a healthy lifestyle in Europe (ie, a PAL of >1.75; reference 41) also exceed the calculated PAL values.

WebSchofield equation. All correlation coefficients were significant, P < 0.001. Bicarbonate (normal range: 2327mmol/L) was measured by an automated potentiometer, thyroid-stimulating hormone (TSH, normal range: 0.34.0mIU/L) by immunofluorometric assays and albumin (normal range: 3.44.8g/dL) by bromcresol green technique. For the adults, data from 180 subjects whose REE was measured with a closed system are depicted in the insets.

Twenty-six patients (9%) had diabetes, 25% had inflammation (defined as CRP 1.0mg/dL) and 20% had severe hyperparathyroidism (defined as PTH 700pg/mL).

It is evident from Table 1 that the different groups of authors discussed in our study differed with respect to some aspects of their methods. A total of 281 CKD patients (124 non-dialysis, 99 haemodialysis and 58 peritoneal dialysis) were included in the present study. Actually, a number of equations have been developed for such a purpose. NCI CPTC Antibody Characterization Program. In conclusion, REE prediction by WHO formulas systematically over- and underestimates REE and is inadequate for use in underweight subjects. The generation of new REE prediction formulas showed no clear advantage of body compositionderived formulas compared with the use of body weight as a predictor (Tables 7 and 9). Hasson RE, Howe CA, Jones BL, Freedson PS.

Firstly, the error of such equations might be attributed to the fact that they were developed for estimating basal metabolic rate and not REE. Resting energy expenditure (REE) prediction equations for adults based on data from subpopulation 1 and from BMI (in kg/m2) subgroups of subpopulation 11. Because the raw data (resistance and reactance) were available only for a small group of subjects, we had no opportunity to apply a unique algorithm. Front Oncol. Accuracy of four resting metabolic rate prediction equations: effects of sex, body mass index, age, and race/ethnicity.

Subpopulations 1 and 2 were matched in age, BMI, and REE (Table 3). WebThe Schofield equations were widely used by dietitians in clinical practice (Reference Judges, Knight and Graham 45) until relatively recently, but key advisory groups now recommend For children and adolescents, the prevalence of BMI under or over a certain percentile (according to reference 32); for adults, the prevalence of underweight (BMI < 18.5), normal weight (BMI of 18.5 to <26), overweight (BMI of 26 to <30), and obesity (BMI 30).

For sex, female = 0 and male = 1. Shetty P, Henry CJK, Black AE, Prentice AM. The knowledge of REE is essential for determining energy requirement since REE is the predominant component of the TEE [19].

Should we still use the Harris and Benedict equations? However, several factors related to subjects (e.g.

WebSchofield equations provided the most accurate REE predictions so are useful for groups.

Takes into account: - Patients weight; Likely stresses imposed by their illness; Current activity levels; Stimulus to metabolism of giving food itself (thermic effect of feeding) Unusual fluid or nutrient losses; Any need to make up nutrient deficits; References 1. As part of a larger project to determine the role of indirect calorimetry in clinical practice, an evidence team identified published articles that examined the validity of various predictive equations for resting metabolic rate (RMR) in nonobese and obese people and also in individuals of various ethnic and age groups.

Do handheld calorimeters have a role in assessment of nutrition needs in hospitalized patients? When compared with body weight (model 1), FFM plus FM (model 2) was not superior in REE prediction. CPT1A in AgRP neurons is required for sex-dependent regulation of feeding and thirst.

The REE error (predicted minus measured) correlated inversely with serum glucose (Harris and Benedict r = 0.15; P = 0.01 and Schofield r = 0.17; P = 0.004), parathyroid hormone (Harris and Benedict r = 0.17; P = 0.004 and Schofield r = 0.14; P = 0.02) and C-reactive protein (Harris and Benedict r = 0.24; P < 0.001 and Schofield r = 0.22; P < 0.001).

Owen OE, Holup JL, D'Alessio DA, et al. MJM and AB-W performed data analyses and wrote the manuscript. Higher differences were seen for children and adolescents (99 and 158 kcal/d for boys and girls, respectively).

Webthe Schofield equation may overestimate energy requirements in older and hospitalized patients, since the data used to develop the equation were based on young males 700.

All values are x SD.

The site is secure. 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).

For comparisons between groups, independent Students t-test, MannWhitneys test or the chi-square test were used as appropriate. and transmitted securely. <<
