Comparative characteristics of physical development of children and adolescents of the 1st and 2nd generation of European natives of the Magadan region

In the paper there are presented results of investigations of indices of the physical development of male adolescents aged of 11-17 years - residents of the 1^st-2^nd generation from new coming European migrants in the Magadan region during 2008-2014. There were observed 418 adolescents - representatives of the 1^st generation, and 463 cases from the 2^nd generation. Representatives of the 2^nd generation in the initial period (11-12 years) were established to show higher tempos of growth. Maximal gains in the body length, body mass, and chest circumference in adolescents of the 1^st generation occur at the age of 13-14 years, but in the 2^nd generation it is seen one year later - at the age of 14-15 years. In adolescents of each generation there was noted the high variability of the level of major indices of the physical development. However, among representatives of the 1^st generation there is less proportion of cases with normal or average values of body length, body mass, and chest circumference along with larger proportion ofpersons with diverse deviations, as well deficit as excess in comparison with the 2^nd generation. At the final stage of the puberty age (17 years) more adolescents with microsomatic (25%) and disharmonic (38.2%) body constitution occur among the subjects from the 1^st generation as compared to those of the 2^nd generation (19.7% and 28.2%, respectively).
