However, obesity screening of the elderly may be less adequate compared to younger people because the former may have less muscle but more body fat, and they may have osteoporosis, which is often found in inhabitants of low or middle-low income countries, especially in women [36, 37]. We used BIA method to estimate BF%. Review articles are excluded from this waiver policy. The data used to support the findings of this study are available from the corresponding author upon request. The authors would like to thank all volunteers who participated in the study. For the highest tertile of waist and hip, the average difference was between 1.67% and 3.29% compared with the Bod Pod estimation. greater muscle mass, leaner, etc. However, it is unknown if some model types (i.e., hand to hand, foot to foot, and hand to foot) are differing in their validity depending on hip and waist circumferences. Our objectives were to find the relationship between HWDI and BF% and to find a BF% prediction model from HWDI in relation to age and gender. Multiple linear and nonlinear regression analysis were used to construct the BF% prediction model. The discrepancies between the studies may be due to various issues including differences in methodology, equations, and athletic population. 38-43, 2004. This study adds to the literature as no research has attempted to test the accuracy of hand to hand, foot to foot, and hand to foot BIA against a gold standard measure in the same study. BMI was calculated using the following equation: weight (kg)/height (). As such, the following areas of research are needed to expand current knowledge on this topic: To conclude, it is likely that BIA is not a suitable body composition assessment method for athletic populations. Contact Us In addition, the SEE values derived from this study were similar to, yet higher than, those of some other studies [16, 29]. Tertile 3 of Hip Circumference Across BIA models. A. Bergsma-Kadijk, B. Baumeister and P. Deurenberg, “Measurement of body fat in young and elderly women: comparison between a four-compartment model and widely used reference methods.,” British Journal of Nutrition, vol. The primary issues with BIA are: One such limitation is the placement of the sensors, and their ability to give readings of total body composition. The path of the electrical current may differ between this method and the hand-held method, and could potentially influence body composition results; though this issue is discussed later in the article. This study was approved by the Faculty of Medicine, Chiang Mai University Ethics Committee. The Bland-Altman was plotted and 1-sample T-test as well as correlation between the average measure and the difference between the two measures was tested. Strengths of this study include the use of Bod Pod to estimate BF%, a well-accepted measure as the criterion method in the interpretation of results between different BIA models. The proportional bias was nonsignificant for all tertiles and across all BIA apparatus. R.

From the results of this assessment method, the manufacturer constructs an equation using the individual variables mentioned previously to determine what the body fat would be. A. Jebb, T. J. Cole, D. Doman, P. R. Murgatroyd and A. M. Prentice, “Evaluation of the novel Tanita body-fat analyser to measure body composition by comparison with a four-compartment model,” British Journal of Nutrition, vol. The measurement of bioelectrical impedance depends on the difference in electrical conductivity between fat-free mass and fat, and the technique measures the impedance of an electrical current passed between two electrodes (typically 800 μA; 50 kHz). Regardless, all devices are still subject to the same limitations that other BIA devices are. We are committed to sharing findings related to COVID-19 as quickly as possible. Deurenberg et al., [23] reported underestimation of fat-free mass when assessing changes in body composition following weight loss.
