Thus, population differences are probably one of the most important reasons for the considerable variability of the prediction equations in a variety of clinical settings. Bland-Altman analysis showed a systematic error for the WHO prediction in males and females (Figure 3). Schofields equation exhibited higher REE [1492 220kcal/day (mean SD)] in relation to Harris and Benedicts equation (1431 214kcal/day; P < 0.001), and both prediction equations showed higher REE in comparison with the reference indirect calorimetry (1352 252kcal/day; P < 0.001). 16.252W + 10.232H - 413.5. Due to the limitations of sophisticated calorimetric methods for evaluating REE in the clinical settings, simple prediction equations of REE are valuable to guide a correct dietary energy supply.

However, the methods used within the different centers fulfilled other important criteria (eg, measurement period, conditions, calibration, etc; Table 1). {{{;}#tp8_\.

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. The five continuum of care criteria that should accompany rectal artesunate interventions: lessons learned from an implementation study in Malawi. The equations used for the predicting REE are as follows: (i) Harris and Benedicts equations [12]: (ii) Schofields equations reported by the World Health Organization [13]: Data are expressed as mean standard deviation (SD), median and interquartile ranges, or proportions. W=weight in kg; H=height in cm. Demographic, clinical and nutritional characteristics of the patients and controls. Thus, the use of total body weight by the prediction equations could be a potential source of overestimation of REE in these particular patients. 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. Nutritional Considerations in Celiac Disease and Non-Celiac Gluten/Wheat Sensitivity.

For instance, the equation developed by Harris and Benedict was based on a sample of young and healthy non-obese men and women and the equation by Schofield was derived mainly from Italian men with relatively high REE values. 2011 Jul;14(4):344-51. doi: 10.1016/j.jsams.2011.02.010. Fat mass (FM) was derived from the equation FM = body weight - FFM, and percentage FM (%FM) was derived from the equation %FM = FM/body weight. REE prediction formulas for specific body mass index groups reduced the deviations. The site is secure. Blood samples were drawn after an overnight fast of 12h just before the indirect calorimetry test. performed a systematic search for publications of REE prediction equations for use in adults, they found a total of 18 equations developed based on gender, age, body weight and/or height. 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. All values are x SD; n in brackets. 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 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. 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 (). /N 3 Schofield equation (SE) A possible additional limitation of this study is the small number of REE data acquired per day. Magnesium: extracellular, intracellular or total magnesium status? 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). In two-factor repeated-measures ANOVA, the interaction term (sex age) was significant for all 3 variables (ie, REE, REEadj1, and REEadj2). It is evident that the WHO prediction equations overestimated REE at low REE, whereas underestimation was observed at high REE (Figure 3). Prediction of REE from 90% to 110% measured by indirect calorimetry was considered acceptable. 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). In the present study, we report an actual German database of REE. Conclusions. However, the US IOM REE data are lower than the present REE data for a German population.

/Creator (Apache FOP Version 1.0) To compare the methodologic approaches used by the various groups of authors discussed in the present study, we tried to obtain as much information as possible from each group of authors. endobj In two-factor repeated-measures ANOVA, the interaction term (sex age) was not significant for any of the 3 variables (ie, REEWHO, REEm REEWHO in MJ/d, and REEm REEWHO as a percentage).

There were also significant differences in REE between underweight, normal-weight, overweight, and obese women and between obese men and the other BMI groups (Figure 2). 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). Hypermetabolism was defined as a measured REE exceeding the predicted values by >20%. Indirect calorimetry and blood sample collection were performed after a 12-h fasting.

There were significant and independent effects of sex, age, body mass or fat-free mass, and fat mass on REE. [Outline of nutritional science.] Schofield- Men 18-29 yrs BMR= (74 x With respect to practical utility, we compared the measured REE of normal and overweight adults with dietary recommended intakes from the Institute of Medicine (IOM; reference 39) and the German (D), Austrian (A), and Swiss (CH) societies for nutrition (DACH; reference 40) (Figure 5). In peritoneal dialysis patients, the Harris and Benedicts equation exhibited similar REE in relation to the reference. We found significant and systematic over- and underestimations between measured and predicted REE (Figures 3 and 4, Table 9). In 180 adults (78 females and 102 males), REE was measured with the use of a closed system. Previous studies using indirect calorimetry have documented the important role of the comorbidities such as diabetes, hyperparathyroidism and inflammation increasing significantly the REE of CKD patients [2933]. In reality, as age increases, the association between weight and Background. For sex, female = 0 and male = 1. The normative data for REE from the Institute of Medicine underestimated our data by 0.3 MJ/d. The duration on therapy was similar between haemodialysis patients [24 (2162)months] and peritoneal dialysis patients [23 (3109)months].

641. CPT1A in AgRP neurons is required for sex-dependent regulation of feeding and thirst. Since there is a lack of studies addressing the applicability of REE prediction equations in CKD, we aimed to evaluate whether the most traditionally used equations of REE are reliable for estimating REE in a CKD population.

Indirect calorimetry may be an important tool when, in the judgment of the clinician, the predictive methods fail an individual in a clinically relevant way. SCHOFIELD EQUATION: BASAL METABOLIC RATE; Weight Our data also provide evidence that prediction could be improved with the use of BMI groupspecific prediction formulas (Table 9). Conclusions: 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. Underweight, normal weight, overweight, and obesity were determined with the use of corresponding actual German BMI percentiles (<10th, >90th, and >97th percentiles, respectively) for children and adolescents (32) and with the use of WHO criteria for adults (33). Thank you for submitting a comment on this article. However, prediction of REE within 10% compared to REE measured by IC (mREE) was only noticed in about 35% of children. Body mass index (BMI) was calculated as body weight divided by squared height.

Shetty P, Henry CJK, Black AE, Prentice AM. A total of 281 CKD patients (124 non-dialysis, 99 haemodialysis and 58 peritoneal dialysis) were included in the present study. This approach provides the calculation of error (mean of the individual differences between two methods) and the limits of agreement (1.96 SD from the mean error). The basis for the FAO/WHO/UNU formulas was the Schofield database covering 114 studies, approximately 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].

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. Rieper H, Karst H, Noack R, Johnsen D. Lhrmann PM, Herbert BM, Neuhuser-Berthold M. Platte P, Wurmser H, Wade SE, Mercheril A, Pirke KM. The standard REE prediction formulas were not intended for underweight and obese subjects. Total energy expenditure (TEE) was calculated as REE multiplied by 1.55, a mean value of the limits of physical activity level factor (1.401.69) for sedentary adults according to the World Health Organization in order to estimate the energy requirement. n = 243. 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. Significant deviations were still observed for underweight and normal-weight subjects.

However, whether these formulas adequately address REE in subjects living in modern, affluent societies is unclear. Do handheld calorimeters have a role in assessment of nutrition needs in hospitalized patients? 8600 Rockville Pike 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). *1 J "6DTpDQ2(C"QDqpIdy~kg} LX Xg` l pBF|l *?

A comparison of FFM calculated with the use of the manufacturer's algorithm (FFMm) with FFM calculated with the use of either Segal's algorithm (FFMs) or Deurenberg's algorithm (FFMd) in a subgroup of 88 subjects from Kiel showed a very close association between FFMm and FFMs and between FFMm and FFMd (R2 values of 0.967 and 0.966, respectively). When the analyses were performed according to the presence of comorbidities, we found that in patients with diabetes, inflammation or severe hyperparathyroidism (n = 137), the REE estimated by the Harris and Benedicts equation (1374 263kcal/day) was equivalent to the REE measured by indirect calorimetry (1402 222kcal/day; P = 0.13).

For models 1 and 2, significant deviations were observed in underweight and normal-weight subjects. The recent population goals for a healthy lifestyle in Europe (ie, a PAL of >1.75; reference 41) also exceed the calculated PAL values. An important element for promoting adequate nutritional status relies on the adequate management of energy balance. Energy expenditure was calculated by using the Weir equation (35) or in the case of chamber measurements by using REE (kJ) = 16.18VO2 + 5.02VCO2 5.99Nexcretion (29, 36).
