Aqueous coefficient as a new anthropometric index

Keywords: analysis of body composition, bioimpedance, water continuum, aqueous coefficient, anthropometry, regression analysis, factor analysis, physiology of childhood

The aim of the study was physiological substantiation for practical applicability of aqueous coefficient using multidimensional statistical data analysis of the cohort study of body composition in 6,543 relatively healthy children and adolescents aged 5 to 17 years (3,108 girls and 3,435 boys) of the towns of Cheboksary and Novocheboksark and regions of the Chuvash Republic, obtained by bioimpedance method. Using a bioimpedance analyzer ABC 02 "MEDAS" in the settings of the Health Center of the Budgetary Institution “Republican Children's Clinical Hospital” under the Ministry of Public Health and Social Development of the Chuvash Republic and visiting medical teams, 6543 relatively healthy children and adolescents aged 5 to 17 residing in the territory of the Chuvash Republic – the towns of Cheboksary, Novocheboksark and Kanashsky, Sumerlinsky, Yadrinsky and Yalchik regions were examined. The methods of descriptive, regression and factor analysis revealed the presence of gender differences in body composition as well as differences between urban and rural populations. Introduction of two new terms – an aqueous continuum and an aqueous coefficient (extracellular water) / (intracellular water) into the experimental and clinical practice was substantiated. A regular decrease in the aqueous coefficient in ontogenesis was revealed. It is concluded that in children up to the age of nine there is a relative predominance of extracellular volume of water over the intracellular one; the aqueous coefficient is a characteristic parameter that reflects the age of an examinee and can be used for a comprehensive assessment of the current status of the aqueous continuum and the state of the cardiovascular system.
