“…In agreement with other research (Fuller et al, 1994), our findings indicated that skinfold measurements are less accurate than BIA in estimating BF, although there is still debate in this area (Kamimura et al, 2003;Norgan, 2005). The adjusted R 2 for the novel Tanita instrument equation is higher than the one derived for skinfolds; thus indicating further variation is explained by the Tanita system.…”

Objective: To validate the Tanita BC-418MA Segmental Body Composition Analyser and four-site skinfold measurements for the prediction of total body water (TBW), percentage fat-free mass (%FFM) and percentage body fat (%BF) in a population of rural Gambian children. Subjects/Methods: One hundred and thirty-three healthy Gambian children (65 males and 68 females). FFM estimated by the inbuilt equations supplied with the Tanita system was assessed by comparison with deuterium oxide dilution and novel prediction equations were produced. Deuterium oxide dilution was also used to develop equations for %BF based on four-site skinfolds (biceps, triceps, subscapular and suprailiac). Results: The inbuilt equations underestimated FFM compared to deuterium oxide dilution in all the sex and age categories (Po0.003), with greater accuracy in younger children and in males. The best prediction of %FFM was obtained from the variables height, weight, sex, impedance, age and four skinfold thickness measurements (adjusted R 2 ¼ 0.84, root mean square error (MSE) ¼ 2.07%). Conclusions: These data suggest that the Tanita instrument may be a reliable field assessment technique in African children, when using population and gender-specific equations to convert impedance measurements into estimates of FFM.

“…Skinfold measurement at four standard sites (biceps, triceps, subscapular and suprailiac) was performed for determining body fat, as the method seems to be superior to bioelectrical impedance analysis for the measurement of this compartment (Kamimura et al, 2003). Body density was calculated from the sum of the four skinfold measurements according to Durnin and Womersley (1974), and the percentage of body fat was then calculated by Siri's (1961) equation . Resting energy expenditure REE measurements were obtained by indirect calorimetry using an open-circuit ventilated computerized metabolic system (Vmax series 29n; SensorMedics Corp; Yorba Linda, CA, USA).…”

Resting energy expenditure and its determinants in hemodialysis patients

Objective: Chronic kidney disease is associated with several metabolic disturbances that can affect energy metabolism. As resting energy expenditure (REE) is scarcely investigated in patients on hemodialysis (HD) therapy, we aimed to evaluate the REE and its determinants in HD patients. Design: Cross-sectional study. Setting: Dialysis Unit of the Nephrology Division, Federal University of São Paulo, Brazil. Subjects: The study included 55 patients (28 male, 41.4712.6 years old) undergoing HD therapy thrice weekly for at least 2 months, and 55 healthy individuals pair matched for age and gender. Subjects underwent fasting blood tests, as well as nutritional assessment, and the REE was assessed by indirect calorimetry. Results: REE of HD patients was similar to that of pair-matched controls (13797272 and 14407259 kcal/day, respectively), even when adjusted for fat-free mass (P ¼ 0.24). REE of HD patients correlated positively with fat-free mass (r ¼ 0.74; Po0.001) and body mass index (r ¼ 0.37; Po0.01), and negatively with dialysis adequacy (r ¼ À0.46; Po0.001). No significant univariate correlation was found between REE and age, dialysis vintage, serum creatinine, urea, albumin, bicarbonate, parathyroid hormone (PTH) or high-sensitivity C-reactive protein (CRP). In the multiple linear regression analysis, using REE as dependent variable, the final model showed that besides the well-recognized determinants of REE such as fat-free mass and age, PTH and CRP were the independent determinants of REE in HD patients (R 2 ¼ 0.64).

“…[16] In addition, analysis of body composition with different techniques, such as bioelectrical impedance analysis [BIA] and dual energy X-ray absorptiometry [DEXA], has also been used to determine nutritional status in this population. [17][18][19] Dual energy X-ray absorptiometry is the gold standard for evaluating body composition in HD patients because this method measures three body components: fat mass, lean body mass, and bone. [20] However, this technique is expensive and not available at all centers.…”

Objective. The aim of the study was to assess the body fat (BF) composition in hemodialysis (HD) patients using anthropometry and bioelectrical impedance analysis (BIA) and investigate relationships between BIA-determined BF composition and nutritional parameters in different weight groupings. Design. Cross-sectional study. Setting. A tertiary-care university hospital. Methods. 164 HD patients (M/F: 89/75, mean age: 48.4 ± 15.8 years, mean HD duration: 58.2 ± 42.6 months) were divided into three groups according to body mass index (BMI): normal weight (NW: BMI 18.5-24.9), overweight (OW: BMI 25-29.9), obese (OB, BMI ≥ 30). Biochemical parameters and BF composition using anthropometry and foot-to-foot BIA were compared between three groups. Results. Ninety-six (59%) patients were NW, 40 (24%) were OW, and 28 (17%) were OB. Average mean skinfold thickness (p = 0.005), mid-arm circumference (p = 0.001), BF% (p = 0.001), and fat-free mass (FFM) (p = 0.03) were all significantly greater in the OB group than in the NW group. Compared to the NW patients, the OB group had significantly higher serum levels of glucose (p = 0.03), total cholesterol (p = 0.02), and triglycerides (p = 0.02), but significantly lower serum albumin (p = 0.05) and blood urea nitrogen (p = 0.05). The OB group also had significantly higher white blood cell count (p=0.002) and serum CRP (p = 0.001) than the NW group. Conclusions. The results suggest that BIA-determined BF composition is correlated with body mass index. In addition, obesity is associated with elevated CRP and white blood cell count and lower serum albumin level in HD patients.
