THE CENTILE METHOD IN THE CHARACTERIZATION OF ANTHROPOMETRIC AND BIOIMPEDANCE PARAMETERS OF YOUNG MEN IN YAKUTIA

Assessing the level of physical development of individual population groups is necessary for the formation of a personalized approach in medicine. The purpose of the study was to develop centile tables on anthropometric and bioimpedance parameters of young men in the Sakha Republic (Yakutia). The young men of the Yakut ethnicity aged 17-21 years were examined; under the age classification of human ontogenesis, they belonged to the youth age period. Anthropometric measurements were carried out according to the classical method of V.V. Bunak. The length and weight of the body, the girths of the chest, waist and buttocks are determined. Absolute and relative values of the main components of the body were determined by bioimpedance measurement (BIA). The analyzer of body composition and balance of water sectors of the body ABC – 01 “Medass” was used. Measurements were carried out according to a standard four-electrode scheme with the attachment of disposable electrodes (Shiller Biotabs® with Ag/AgCl coating) in the area of the wrist and ankle joints. The obtained material was processed by the method of variation statistics using the SPSS 17.0 application software package. To assess the distribution of anthropometric and bioimpedance indicators of young men in Yakutia in percentage terms, a centile analysis was carried out. The cents P5, P10, P25, P75, P90, P95 were applied. The study revealed regional peculiarities of overall dimensions and body composition of young Yakut men. Lower indicators of body weight, fat mass, active cell mass and musculoskeletal mass of Yakuts were established in comparison with the data of young men from other regions of Russia. Centile tables of parameters of body length and weight, girth dimensions of the chest, waist and buttocks, body mass index, bioimpedance indicators of fat mass, active cell mass, musculoskeletal mass, lean mass of Yakut boys were developed. These tables allow us to assess the level of physical development of young Yakut men for the formation of a personalized approach in medicine. The results obtained can be used in conducting comparative analyses with the indicators of young men living in other regions.
