Abstract

To establish the anthropo-ecological portrait of the current population of Yakutia, it is necessary to study the regularities of the variability of physical status in different sex groups and develop regional standards of the physical development of different age-sex groups of the population with regard to the peculiarities of the environment. The aim of this study was to do research on the sex features of anthropometric, cephalometric and bioimpedance parameters in ethnic Yakut students. The measures of 228 Yakut girls and 168 Yakut youths born and permanently residing in Yakutia were analyzed. The anthropometric measurements were performed using the V.V. Bunak’s method (1941), somatotypingones - using the Rees-Eysenck index (1945). The head type was determined by the cephalic index, the face type - by the upper facial index. The bioelectrical impedance analysis with the use of ABC-01 Medass analyzer was performed to estimate body composition. The adipose tissue mass (AM), skeletal muscle mass (SMM), lean mass (LM), active cell mass (ACM) and phase angle (PA) were determined. The obtained data were processed by the method of variation statistics with the use of SPSS 17.0 software package. Overall measures of the soma of the examined groups had sex features of body organization that were expressed in significantly higher values of all measured parameters in the youths of Yakutia. In our study, the sexual dimorphism in the distribution of somatotypes by the Rees-Eysenck index was not identified. The analysis of the cephalometric measures revealed reliably higher parameters of absolute head sizes in the youths. Sex differences in the distribution of head and face types were not found in the examined ethno-age group. Significantly larger absolute amount of AM was established in the girls. The measures of SMM, ACM and LM were reliably higher in the youths. The values of active and reactive tissue resistance were reliably higher in the girls. Sex features of the anthropometric, cephalometric and bioimpedance parameters of the students were established. The conducted study presents the anthropo-ecological image of this age-sex group of the population of Yakutia.
