Changes in the morphological profile of adolescents in Penza and Penza region over 15 years

Abstract

Determining the physical development of the population of the regions is quite convenient within the framework of identifying the level of public health, while it is very important to track changes in the physical health of adolescents entering the reproductive phase of life, depending on the periods of development of the country. The aim of this study was to identify significant changes in the morphological profile of adolescents in Penza and Penza region over 15 years. Material and methods. The object of the study were 492 people of both sexes, 16 to 21 years of age, born and permanently residing in Penza and settlements of Penza region, divided into two groups according to the year of birth (group 1 – born in 1986–1990, 2 group – born in 1999–2004). Anthropometry and somatometry were carried out by the method of V.V. Bunak with subsequent comparative analysis of statistical indicators. For a comparative assessment of the level of physical development and identification of significant differences between the two groups, the following index methods were used: body mass, Rohrer, Erisman, Pignet, Rees-Eysenck, Tanner. Results and discussion. Based on the results of the study, it was concluded that Penza residents of 1999–2004 birth, compared with predecessors, there was a significant increase in the studied absolute anthropometric parameters with a simultaneous shortening of the hand and shin length. Among the representatives of the modern youth of the region, when compared with the group of 1986– 1990 birth, the number of people with mesomorphy increased by 2.2 times, the number of people with overweight – by 1.5 times, the number of individuals with a narrow chest – by 1.3 times, the number of cases of a low degree of physical development, hypersthenic type (according to the results of calculating the Rees-Eysenck index) – by 1.2 times, at the same time the number of normosthenics increased by 1.1 times (according to the results of calculating the Pignet index). Conclusions. Comparative analysis showed significant changes in the constitution of the autochthons of Penza region of adolescents over 15 years.
