By contrast, 2 groups of authors (28, 29) applied Segal's algorithm (22), and another group (30) applied Deurenberg et al's algorithm (23). In peritoneal dialysis patients, the Harris and Benedicts equation exhibited similar REE in relation to the reference. WebThe Schofield equation estimate was 798 +/- 595 kcals/24 hrs and the White equation estimate was 815 +/- 564 kcals/24 hrs (p = not significant). Although numerous equations have been formulated for predicting metabolic rates, there is a lack of studies addressing the reliability of those equations in chronic kidney disease (CKD). Skewed variables or non-linearly related variables were log-transformed. Cross-Validation of Resting Metabolic Rate Prediction Equations. 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. Dialysis patients underwent haemodialysis or peritoneal dialysis therapy for at least 3months. However, the US IOM REE data are lower than the present REE data for a German population.

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). 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). According to the WHO criteria (33), a high prevalence of overweight and obesity was found in the whole study population. MJM was responsible for the study design. In two-factor repeated-measures ANOVA, the interaction term (sex age) was significant for all 3 variables (ie, REE, REEadj1, and REEadj2).

The agreement of the REE prediction equations with the indirect calorimetry is shown in Figure2. Federal government websites often end in .gov or .mil. Current standards are based on measurements made in the first part of the past century in various races and locations. FFM, fat-free mass; FM, fat mass; REE, resting energy expenditure. 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. 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. The total number of subjects (children, adolescents, and adults) who served as the basis of this study was 2528 (1027 males and 1501 females). Accuracy of four resting metabolic rate prediction equations: effects of sex, body mass index, age, and race/ethnicity. We found significant and systematic over- and underestimations between measured and predicted REE (Figures 3 and 4, Table 9). sterreichische Gesellschaft fr Ernhrung, Schweizerische Gesellschaft fr Ernhrungsforschung, Schweizerische Vereinigung fr Ernhrung. Should we still use the Harris and Benedict equations?

An assessment of energy needs is a necessary component in the development and evaluation of a nutrition care plan. Physical activity and fat-free mass during growth and in later life. These formulas were cross-validated in subpopulation 2, and a high correlation (r = 0.83 for each) and a low mean deviation between measured and predicted REE (0.04 and 0.07 MJ/d, respectively) were obtained (Table 9). {{{;}#tp8_\. REE prediction from a weight groupspecific formula is recommended in underweight subjects. Sedentary is very physically inactive, inactive in both work and leisure.

Hypermetabolism, is it real? However, whether these formulas adequately address REE in subjects living in modern, affluent societies is unclear. 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.

Physical characteristics of the study population 1. 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. In a comparison of the normative REE data from the IOM (42) with our data, a mean deviation of 82 kcal/d (range: 0187 kcal/d for the different age and sex groups) was observed. 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. The intraclass correlation of the REE measured by indirect calorimetry with the Schofields equation was r = 0.48 (P < 0.001) and with the Harris and Benedicts equation was r = 0.58 (P < 0.001). Acceptable REE prediction, from 90% to 110%, was found in 47% of the patients by using the Harris and Benedicts equation and in only 37% by using the Schofields equation (Figure3). Bland and Altman plot analysis allowed us to evaluate the agreement between the prediction equations and the reference for the REE measurements. Energy metabolism. Dividing the subgroup of underweight subjects from subpopulation 2 into severely (BMI < 17; n = 21) and less severely (BMI of 1718.5; n = 28) underweight showed significantly higher overestimations of REE by WHO models 1 and 2 in the severely underweight group than in the less severely underweight group. Comparisons of REE predicted by the equations with REE measured by indirect calorimetry are presented in Figure1. Magnesium: extracellular, intracellular or total magnesium status? 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]. 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).
