Body composition analysis in older adults with dementia. Anthropomentry and bio-electrical impedance analysis: a critical review MAC Martin, B de Mateo Silleras… – European journal of Clinical Nutrition, 2014
Conclusion – Using Bio-electrical Impedance Vector Analysis errors are minimized, as there is no need for the subject to be normally hydrated and it does not require the use of predictive models
BIO-ELECTRICAL IMPEDANCE TECHNOLOGY FOR EVALUATING HUMAN BODY COMPOSITION PARAMETERS:â€œAN ADVANCED DIAGNOSTIC …R Subhedar, V Subhedar, P Dave, P Mishra, A Kaur – Int J Physiother Res, 2014
Conclusion -Thus, Bio-electrical Impedance method proved to be accurate, safe and simple technology in assessing body composition parameters and thereby analyzing physical fitness
Analysis of Body Composition: A Critical Review of the Use of Bio-electrical Impedance Analysis MS Mialich, JMF Sicchieriâ€¦ – International Journal of Clinical Nutrition, 2014 1-10
Conclusion – In general, multi-frequency impedance does not improve the estimate of body composition compared to single-frequency impedance, but can provide an accurate and precise estimate of TBW and ECW
Segmental bio-electrical impedance analysis:an update. Ward LC. Curr Opin Clin Nutr Metab Care 2012; 15 (5):424-9.
Conclusion – Segmental impedance, impedance approaches, provides indirect prediction of body composition whose accuracy is yet to achieve that of reference techniques
Low phase angle determined by bio-electrical impedance analysis is associated with malnutrition and nutritional risk at hospital admission. Kyle U, Genton L, Pichard C. Clinical Nutrition 2012; 1-6.
Conclusion – There is a significant association between low PhA and nutritional risk, LOS and non-survival. PhA is helpful to identify patients who are at nutritional risk at hospital admission in order to limit the number of in-depth nutritional assessments.
A comparison of dual energy X-ray absorptiometry and bio-electrical impedance analysis to measure total and segmental body composition in healthy young adults. Leahy S, Oâ€™Neill C, Sohun R, Jakeman P Eur J Appl Physiol 2012; 112: 589-95.
Conclusion – Though statistically significant, the small difference (~ 4%) between the methods indicates that the BIA may be used interchangeably with DXA in the measurement of appendicular fat free mass in healthy young adults.
Bio-electrical phase angle and impedance vector analysis e Clinical relevance and applicability of impedance parameters. Norman K, StobÃ¤us N, Pirlich M, Bosy-Westphal A. Clinical Nutrition 2012; 1-8.
Mally, K, Dittmar M. Comparison of three segmental multi-frequency bio-electrical impedance techniques in healthy adults. Annals of Human Biology 2012; Early Online: 1-11
Conclusion – After this review, we conclude that BIA is an important instrument for health professionals and that its use can provide safe data about body composition, in addition to complementary data about the clinical course of patients followed up on a medium- and long-term basis.
Bio-electric impedance phase angle is associated with hospital mortality of geriatric patients. Wirth R, Volkert D, Rosler A, Sieber CC, Bauer JM. Arch Gerontol Geriatr 2010; 51: 290-4.
Conclusion – A significant difference of PA (50 kHz) between survivors (4.2Â±1.1Â°) and non-survivors (3.6Â±1.2Â°; p<0.001) of the hospital stay could be detected.
Estimation of segmental fat free mass in Taiwanese elderly females by bioelectrical impedance analysis with new mathematical model. Hsieh K, Kao M, Jang T et al. African Journal of Biotechnology 2011; 10 (75): 17339-46
Conclusion – After this review, we conclude that BIA is an important instrument for health professionals and that its use can provide safe data about body composition
