Daily Calorie Intake, Level of Physical Activity and Morphological Status of Children and Adolescents in Three Cities of Russian Federation

The study is devoted to identifying the intergroup variability of morphological characteristics, body composition, in-dicators of physical activity and nutritional status in modern adolescents of the cities of Elista, Arkhangelsk and Moscow. The increased body weight of 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 musculo-skeletal component, that is, increased body weight values are associated in this group to a greater extent with its fat component. Residents of Moscow have intermediate values among the three groups surveyed for most morphological in-dicators and minimum indicators of exchange. 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-eco-nomic differences in the surveyed cities

Secular Changes in Mongolia: Shift in Tempos of Growth

The patterns of secular changes in children and adolescents of the city of Ulаan-Baatar in the Republic of Mongolia measured in 2010–11 by the authors and in the group of children observed by Uranchimeg in the same place in 19891 have been analyzed. Total number of the investigated children and adolescents from 9 to 17 years of age was 1351. The last survey was conducted in accordance with bioethical procedures. The program included standard anthropometric measurements, descriptive characteristics2 and pubertal stages evaluation3. Mean age of development of secondary sexual characteristics was calculated graphically. For most of the anthropometric indices significant differences between the Mongolian teenagers of two series of measurements were revealed. The patterns of secular changes in body size confirmed the interaction of »tempo and amplitude«4: significant changes in pubertal growth were observed with the same average values at 16–17-year old boys and girls. The increase in body circumferences observed in modern Mongolian schoolchildren was possibly based on the increase of body fat component, parallel to the global trend worldwide

Changes in the Anxiety of Moscow Students during the COVID-19 Pandemic

This work is devoted to assessing the changes in anxiety among Moscow students during the COVID-2019 pandemic. The material was collected in comprehensive examination of 18–25-year-old students studying at Lomonosov Moscow State University (residents of Moscow and the Moscow region). The study included longitudinal and cross-sectional components. The methodology included a social questionnaire about the peculiarities of the self-isolation regime, living conditions of the respondent, professional employment, etc. and the scale of situational and personal anxiety of C.D. Spielberger in the Russian-language adaptation of Yu.L. Khanin. A total of 284 questionnaires have been analyzed. In 2020, two consecutive waves of infection were recorded in Russia: in May and in December. During the first wave, severe social restrictions and a temporary lockdown were introduced in Moscow, and the second one took place under conditions of significantly less restrictions, although it was marked by a large number of infections. Different social load and adaptation to the pandemic led to the fact that the behavioral manifestations of stress and the level of situational anxiety among Moscow students increased significantly at the beginning of the pandemic, but subsequently began to decrease. It can be concluded that among university students there is a social and psychological adaptation to new norms of life, which are dictated by the conditions of the COVID-19 pandemic
