limitations of schofield equation

The present study demonstrated that the most frequently used Nutritional Considerations in Celiac Disease and Non-Celiac Gluten/Wheat Sensitivity. Oxford University Press is a department of the University of Oxford. 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). In this cross-sectional study, the indirect calorimetry test, nutritional assessment and fasting blood tests were all performed on the same day. WHO prediction, which uses body weight as one determinant, systematically overestimates REE at low metabolic rate (Figure 3) and thus low body mass. Bars with different letters are significantly different, P < 0.05 (ANOVA and Bonferroni post hoc test). *P < 0.001 Harris and Benedict > indirect calorimetry; **P < 0.001 Schofield > Harris and Benedict and indirect calorimetry. In peritoneal dialysis patients, the Harris and Benedicts equation exhibited similar REE in relation to the reference. In addition, the analyses by quartiles of TEE exhibited kappa statistic of 0.15 between Harris and Benedicts equation and indirect calorimetry, and 0.12 between Schofields and indirect calorimetry, indicating the lack of agreement between the predicted and measured methods for estimating energy requirement of these patients. Higher differences were seen for children and adolescents (99 and 158 kcal/d for boys and girls, respectively). Blood samples were drawn after an overnight fast of 12h just before the indirect calorimetry test. The site is secure. This figure can then be used to design a dietary regime that places the subject in calorie deficit or surplus, depending on whether The errors are minimized in the presence of comorbidities such as diabetes, inflammation and severe hyperparathyroidism. Bethesda, MD 20894, Web Policies [11] developed predictive equations for BMR The Schofield Equation allows one to estimate the basal metabolic rate (BMR) in calories based on a few simple variables: gender, age, and weight. Most of our subjects were investigated with the use of standard BIA (Table 1). REE prediction from weight groupspecific formulas is superior to that from weight groupunspecific formulas. endobj The relation between REE and FFM in the male adolescents with SCA (upper solid line) was significantly greater than that in the As far as we are concerned, this is the first study that investigated the reliability of prediction equations for estimating REE in a large cohort of CKD population by comparing with indirect calorimetry. Tissue determinants and cellular corollaries. 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). The PALs necessary to meet the IOM recommendations exceed the measured PALs of most subjects in Western Europe (ie, 1.481.70 in old and young females and 1.541.85 in old and young males; reference 17). Resting energy expenditure (REE) prediction equations developed for children and adolescents aged 517 y1. *P < 0.05, **P < 0.01 patients vs control, independent Students t-test or MannWhitneys test. Weight was measured to the nearest 0.1kg and height to the nearest 0.1cm with a stadiometer. The equation proposed by Harris and Benedict, in 1919, has been the most traditionally used for clinical and research purposes [12]. Application of resting energy expenditure (REE) prediction equations from the World Health Organization (WHO) to subpopulation 2 and BMI subgroups of subpopulation 2 and cross-validation of equations derived from data from subpopulation 1 and BMI subgroups of subpopulation 11. 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). 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. When compared with measured REE, REE predicted according to WHO formulas showed considerable deviations (Figure 3). Because obesity research was the main focus in some of the study centers, all age groups except young adults had a high prevalence of overweight and obesity. There was a large limit of agreement between both prediction equations and the reference indirect calorimetry among non-dialysis patients (Figure2A) and, particularly, among dialysis patients (Figure 2B and C). /Creator (Apache FOP Version 1.0) Forty-nine subjects were diagnosed with anorexia nervosa according All subjects were white, nonpregnant, and nonlactating. Eurodiet Core Report. J Am Diet Assoc. Background: Reference standards for resting energy expenditure (REE) are widely used. Although this idea has been questioned (1), it should be readdressed. REE predicted by the equations against the reference indirect calorimetry. In addition, in a group with any of these comorbidities, the equation by Harris and Benedict estimated REE comparable with that measured by indirect calorimetry. SCA. Search for other works by this author on: All data were recorded in a database with the use of a personal computer. Chmielewska A, Kujawa K, Regulska-Ilow B. Int J Environ Res Public Health. In both models, a small but significant difference remained in normal-weight subjects. The nephrotoxicity of bortezomib: did we miss a complication after 20 years of use and multiple landmark trials? For sex, female = 0 and male = 1. Bland and Altman comparative analysis for REE predicted by the Harris and Benedicts (HB) and Schofields equations against indirect calorimetry (IC) in non-dialysis, haemodialysis, peritoneal dialysis and controls [men (filled diamonds) and women (unfilled diamonds)]. The total number of subjects (children, adolescents, and adults) who served as the basis of this study was 2528 (1027 males and 1501 females). A reference database has to have a sample size with an acceptable statistical power and be reasonably representative of the variables tested. FFM alone explained 61.7% of the variance in REE in adults. WebSchofield Equation for Females. 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 Overestimation was greatest with the equation proposed by Schofield followed by the one by Harris and Benedict. Demographic, clinical and nutritional characteristics of the patients and controls. Each skinfold value represented the mean of 3 consecutive measurements taken by the same investigator. However, prediction of REE within 10% compared to REE measured by IC (mREE) was only noticed in about 35% of children. Vinken AG, Bathalon GP, Sawaya AL, Dallal GE, Tucker KL, Roberts SB. 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). FFM, fat-free mass; FM, fat mass. These shortcomings are due in part to the heterogeneity of the reference study populations, methodologic drawbacks, and the variability of REE.

Clipboard, Search History, and several other advanced features are temporarily unavailable. However, whether these formulas adequately address REE in subjects living in modern, affluent societies is unclear. REE prediction formulas for specific body mass index groups reduced the deviations.

Physical activity level (PALs) necessary to maintain body weight when following the recommendations from the IOM (PALIOM) or the DACH (PALDACH) were calculated as reference energy intake/REE. Would you like email updates of new search results? Multivariate regression analysis explained up to 75% of the variance in REE. /Length 11 0 R Hypometabolic subjects were below the 10% prediction level (25). Schofield Equation Males. 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). No author used a population-specific algorithm. Height is not 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. Accuracy of four resting metabolic rate prediction equations: effects of sex, body mass index, age, and race/ethnicity. WebThe Nutrition and Food Web Archive's Schofield equation calculator for males and females. Interaction terms between sex and weight and between sex and FFM were significant for adults but not for children and adolescents. Before WHO prediction equations systematically overestimated REE at low REE values but underestimated REE at high REE values. The database includes 2528 subjects with a wide age range. W=weight in kg; H=height in cm. In order to overcome these limitations, Anjos et al. 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). (Carnegie Institute of Washington Publication 279. Normalization of body-composition data for different bioelectrical impedance analyzers and equations used could not be performed (, \[\mathrm{REE}_{\mathrm{adjusted}}{=}\mathrm{REE}_{\mathrm{measured}}{+}{[}(\mathrm{FFM}_{\mathrm{group\ mean}}{-}\mathrm{FFM}_{\mathrm{measured}}){\times}\mathrm{slope}{]}\], With the use of multivariate regression analysis with REE as the dependent variable, 72% of the variance in REE was explained by either, \[\mathrm{REE}\ (\mathrm{kcal}/\mathrm{d}){=}20.695{\times}\mathrm{FFM}\ (\mathrm{kg}){+}475.418\ {[}{\pm}216\ (\mathrm{SE})\ \mathrm{kcal}{]}\], \[\mathrm{REE}\ (\mathrm{MJ}/\mathrm{d}){=}0.0866{\times}\mathrm{FFM}\ (\mathrm{kg}){+}1.989\ {[}{\pm}0.905\ (\mathrm{SE})\ \mathrm{MJ}/\mathrm{d}{]}\]. The Schofield equations resulted in positive estimates in all but one woman and one man. CO 2/RQ Age (years) Men Women Schofield equation (kJ/day) 1017 (74 W) + 2754 (56 W) + 2898 WebThe Schofield equation estimate was 798 +/- 595 kcals/24 hrs and the White equation estimate was 815 +/- 564 kcals/24 hrs (p = not significant). There were no significant differences between the subgroups in any of the measured variables (Mann-Whitney U test). Sedentary is very physically inactive, inactive in both work and leisure. 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. The WHO reference population also included a substantial number of subjects with a BMI < 17. An important element for promoting adequate nutritional status relies on the adequate management of energy balance. Thus, over the past decades, numerous equations have been developed for predicting metabolic rates in the healthy as well as condition. This number increased to 71% with the further inclusion of FM, age, and sex (Table 7).

SCHOFIELD EQUATION: BASAL METABOLIC RATE; Weight The deviations between measured and predicted REE were significant in model 2. They were instructed to avoid hyperventilation, fidgeting or falling asleep during the test. Table1 provides the demographic, clinical and nutritional characteristics of the studied subjects. Front Oncol. @Rt CXCP%CBH@Rf[(t CQhz#0 Zl`O828.p|OX Unauthorized use of these marks is strictly prohibited. 441. RMR estimation errors would be eliminated by valid measurement of RMR with indirect calorimetry, using an evidence-based protocol to minimize measurement error. Basal metabolism related to sex, stature, age, climate and race.

Chronic kidney disease (CKD) is recognized as an important public health problem, in which the incidence has increased markedly in the last few years [1]. Nineteen (20%) measurements were >110% above the age-appropriate Schofield-predicted equation, and 30 measurements (32%) were <90% below that predicted by Schofield. Should we still use the Harris and Benedict equations? The agreement of the REE prediction equations with the indirect calorimetry is shown in Figure2. These numbers are 5.8% higher than the respective PALs derived from the DACH estimates (ie, 1.491.73). Two most traditionally used equations for estimating REE were chosen for comparison with the REE measured by indirect calorimetry: (i) the equation proposed by Harris and Benedict, and (ii) the equation proposed by Schofield that is currently recommended by the FAO/WHO/UNU. 63 W + 2 896. All control subjects had normal renal and thyroid function, and none of them were taking any medication. 16.969W + 1.618H + 371.2. FFM, fat-free mass; FM, fat mass; REE, resting energy expenditure. ], Grundri der Ernhrungslehre. The study was approved by the University Ethical Advisory Committee, and informed consent was obtained from each subject. 700. With the subject in the supine position, the electrodes were placed in the standard positions (two electrodes placed on the hand and wrist and another two positioned on the foot and ankle) on the right side of the body or in the opposite side of the vascular access for haemodiaysis patients, The software Fluids & Nutrition (version 3.0) provided by the manufacturer was used to estimate body composition.
