The study examines certain aspects of the physiological and mental states of students caused by the conditions of social isolation caused by the COVID-19 pandemic and the need to study remotely. 189 respondents (84.6% female, 15.4% male) aged 17 to 27 years were interviewed. The data was collected remotely (using a Google form) between November and December 2020. The following methods were used: the author’s questionnaire aimed at evaluating the regime moments, eating habits and physical activity of students, as well as their academic load; the questionnaire “Well-Being, Activity, Mood”; the Beck Depression Inventory; the Spielberger-Hanin anxiety scale. The results showed that in the conditions of distance learning, the lifestyle of a significant proportion of students is characterized by pronounced deviations from the recommended values. Sleep deprivation, an unbalanced diet, a decrease in physical activity — all this, along with a pronounced academic load of medical students, leads to a deterioration in their functional state. A close relationship between the physical and emotional well-being of students was revealed. At the same time, the main predictors of physical well-being are regular physical activity and commitment to a healthy life- style, while emotional well-being is largely determined by the personal characteristics of students and the ability to adapt to a new learning regime.
As part of the study, the physical development of adolescents was evaluated depending on the level of daily motor activity and individual anthropometric indicators of professional athletes. The physical development indicators of 423 boys aged 16 to 18 years were analyzed, which were divided into 3 groups depending on the level of daily physical activity: professional athletes, with additional physical activity, with the usual level of physical activity. The data were collected as a result of a routine medical examination in the period from June to October 2022. The results showed that children aged 16 and 17 with a normal level of motor activity were statistically significantly lower and had less body weight compared to the other groups. The analysis of the fatness index also confirmed the data obtained in the age group of 18‑year-olds. The largest proportion of children (at 16 years — 17.6 %; at 17 years — 33, %) with disharmonious or distinct disharmonious physical development was revealed in the group of children with normal physical activity; no cases of distinct disharmonious level of physical development were found among adolescent athletes. Statistically significant differences in anthropometric indicators among professionally engaged in sports adolescents aged 16 to 18 years were not revealed, while in children with a normal level of physical activity in these age groups, changes in indicators are pronounced, which may indicate an earlier and smoother biological development of adolescent athletes. The use of mass-growth indicators makes it possible to more accurately assess the achieved level of physical development and the level of its harmony.
The problem of eating disorders among young people is becoming more common. Exactly at a young age that basic habits are formed, a food culture is laid. At this age, there is a period of increased attention to one»s own appearance, a desire to meet the «standards» accepted in modern society. However, for a significant part of modern youth, nutrition and the level of physical activity do not meet hygienic standards. In turn, a balanced diet and an adequate level of motor activity are predictors of optimal functioning of the body, determining the quality of human life. In this regard, it is relevant to study the relationship of the characteristics of eating behavior with the parameters of quality of life, depending on the level of physical activity. 60 adolescent girls aged 14–17 years were examined, who were divided into 2 groups depending on the level of physical activity. The diet and nutrition regime (questionnaire data), features of eating behavior (DEBQ), the emotional state of respondents (Zung Scale) and quality of life parameters (PedsQL questionnaire) were analyzed. It was found that the majority of respondents have irrational nutrition, but more significant eating disorders were found in girls who do not play sports. Athletes are characterized by higher indicators of physical and emotional functioning and quality of life in general. Girls who do not play sports demonstrate high indicators of social and role functioning, while they have a high intensity of depressive symptoms. There is a relationship between the integral indicator of quality of life and the emotionogenic type of eating behavior. For female athletes, this connection is mediated by external factors, and for female students — by internal experiences. The revealed interrelations between the peculiarities of eating behavior and the quality of life of young people determine the need for additional attention to the issues of hygienic regulation of the diet, increasing physical activity, which will increase adherence to the principles of a healthy lifestyle.
The coronavirus pandemic has made significant adjustments to the educational process, including the higher education system. The purpose of the study: to study the features of the daily routine, motor activity and nutrition, to assess the psycho-emotional indicators, including the level of depression, anxiety in junior students of various specialties during distance learning. Materials and methods: the survey involved 133 respondents (84.6 % female, 15.4 % male) aged 17 to 22 years (M = 18.89; SD = 1.52). The data was collected remotely between November and December 2020. The following methods were used: the author’s questionnaire aimed at studying the regime moments, eating habits and physical activity of students, as well as the assessment of the academic load, the questionnaire «Well-being, activity, mood», the Beck Depression Inventory, the Spielberger — Hanin anxiety scale (STAI). The results obtained showed that within the framework of distance learning in self-isolation, such deviations from the recommended hygienic parameters were revealed in junior students, such as an unbalanced diet, a reduced level of physical activity, an increase in school time and sleep deprivation. Conclusion: a close relationship between the physical and emotional states of students is revealed. At the same time, it is the nature of physical activity that is a parameter that combines the physical and emotional well-being of students. The lack of formation of psychohygienic attitudes among students actualizes measures aimed at better coordination of the educational process, activation of curatorial support for students, as well as the development and communication of recommendations to students on the organization of regime moments during distance learning.
