Abstract
A comprehensive multi-stage expedition study of healthy adolescents from different ethnic groups of the Stavropol Territory has been carried out. On the basis of the heart rate variability data, there has been determined dominant influence of the sympathetic nervous system, expressed stress and strain of the regulatory systems in the adolescents, which were more developed in the Russian girls. Taking into account ethnic differences, there have been revealed qualitative and quantitative differences between the basic parameters of the peripheral blood, characterized by a relative increase in the level of red blood cells and hemoglobin in the Russian schoolchildren, a large volume of red blood cells in the Turkmen girls and the largest amount of platelets in the Turkmen boys. The level of these hormones in the groups of the adolescents of different nationalities was within the age norm, with higher cortisol values observed in the Russian adolescents of both sexes, what indicated a higher tension of adaptation mechanisms in the group of the Russian schoolchildren. Concentration of sex hormones in the blood serum was higher in the Russian boys and the Turkmen girls. Identified variations of the studied parameters were probably caused by influence of natural-climatic factors on the body, as well as by specificity of metabolic regulation of the growing organism and the adolescents' ethnicity. © Northern State Medical University
