Objective of the study was to identify the intergroup variability of morphological characteristics, as well as indicators of physical activity and nutritional status in modern adolescents.
Materials and methods. The paper provides the results of a comprehensive examination of adolescents in the cities of Elista, Arkhangelsk and Moscow. The analysis included morphological characteristics, body composition indicators, as well as personal data, taking into account the calorie daily calorie intake, as well as the amount of time spent on physical activity and work in conditions of hypodynamia.
All calculations were performed with the Statistica 12.0 software package. The choice of data processing methods was determined after checking the normality test for the number of indicators, therefore, to compare the means in the case of metabolic parameters, as well as indicators of the caloric content of the diet and the level of physical activity, the Kruskell-Wallis test was used (the non-normal distribution was confirmed by the Kolmogorov-Smirnov test). In other cases, the assessment of intergroup differences was carried out using the methods of one-way ANOVA
Results and conclusion. It has been recorded that the overweight in Arkhangelsk adolescents of both sexes determines the high values ​​of basal metabolic rates in this group. At the same time, a low level of physical activity has a negative effect on the development of the musculoskeletal component, that is, increased body weight values ​​are associated in this group to a greater extent with its fat component. Residents of the capital have intermediate values ​​among the three groups surveyed for most of the morphological indicators and minimum indicators of exchange. In this case, however, it is this group that is characterized by the maximum amount of time allocated to physical activity. The results obtained indirectly indicate the presence of a certain level of socio-economic differences in the surveyed cities.

Keywords: modern children and adolescents, physical activity, calorie intake, body composition, anthropometry
