ИСТИНА

Due to its simplicity, easy to use, non-invasiveness and relatively low cost, bioelectrical impedance analysis (BIA) represents a most widely used technique for the assessment of body composition both at the individual and population levels. Previously, we have reported the results of bioimpedance study of 819,808 Russian males and females aged 5-97 years, who were assessed cross-sectionally in 2010-2012 within the Russian network of Health Centers (HCs) by the same type of bioimpedance meter, ABC-01 ‘Medas’. Here, we describe an updated 2010-2015 HCs’ bioimpedance measurements database consisting of more than 1.5 mln records. The database represents a significant part (1.2%) of the Russian population and shows fairly good coverage (62 out of 85) of the Russian regions. We provide an updated growth reference curves for anthropometric and body composition parameters as well as estimates of malnutrition prevalences and epidemiological risks depending on age and sex. In addition, geographical distributions of BIA estimates of the Heath-Carter somatotype in children and adolescents are analyzed.
