Aim. To identify the variability of somatometric parameters and body composition in young people of certain constitutional types and social groups. Material and methods. The survey involved 328 people (162 boys and 166 girls) who lived in different social environments. The representatives of the control group were brought up in a well-off family, and the persons of the main group lived in dysfunctional families. The measurement methods included the main indicators of total body size. Results. Data on the degree of severity of the main components of body weight in young people are presented and significant differences are established among representatives of individual constitutions and social groups. The shown relationships between the main tissue components of body weight and soma allow us to scientifically justify the development of corrective rehabilitation programs to reduce the risk of developing prenosological conditions. Conclusions. The comprehensive study of the somatic status and body composition of young people expands the understanding of the differences in the morphofunctional parameters of the human body. The obtained results of the study allow us to more objectively characterize the structural and functional organization of the soma at this stage of development and to establish the influence of social factors on the vital activity of the organism.
