“…HR variability (HRV) is highly efficient in studying the effects of educational environmental factors on the growing body in children. The factors primarily include lack of exercise [ 3 – 5 ] and digital educational technologies, which have come into broadly use in the past years [ 6 , 7 ].…”

Indicators of the cardiovascular system, including heart rate (HR) and blood pressure (BP) variability parameters, were analyzed in primary school students with different computer screen times. The study included 4084 students of grades 1–4 (age 7–12 years) from 66 Moscow schools. The screen time at school and out of school was assessed by teachers, based on the national Sanitary Rules and Regulations: 0, no screen time; 1, screen time matching hygienic standards; 2, screen time at least twice greater than recommended. Physiological examinations were carried out by spiroarteriocardiorhythmography with a face mask, the conditions corresponding to the functional stress test (mild hypercapnia/hypoxia). Testing took place in spring and autumn (independent samples). Statistical data processing was performed using nonparametric criteria. It was revealed that the introduction of computer technologies in school lessons within the limits of hygienic standards was accompanied by an increase, within the normal range, of systolic BP in girls at the end of grade 2 and 4 and in boys at the beginning and end of grade 4. Screen time at least twice higher than the hygienic standard did not have an additional effect on BP, but provoked shifts in the function of autonomic regulation. Boys were more sensitive to the influence of this environmental factor. Their pattern of seasonal variability in total power (TP) of the HR variability spectrum was reversed compared to that of children who did not use computers at school; i.e., higher TP values were observed in spring. In grade 4, the process was accompanied by an increase in spontaneous arterial baroreflex sensitivity and a decrease in the relative power of the LF range in the variability spectrum of systolic BP. The changes were assumed to reflect the adaptive response to changes in educational environment.

Introduction: A widespread intensive use of electronic devices by modern young people negatively affects their health emphasizing the importance of raising awareness of users about health risks of the uncontrolled use of gadgets and developing appropriate safety skills. High school students can get necessary information in medical institutions, at school, and at home. The objective was to study the role of parents, teachers, and healthcare professionals in forming knowledge, skills and abilities of the safe use of digital devices and related components of a healthy lifestyle in seniors. Materials and methods: In the light of the objective, a special online questionnaire-based survey was conducted in 2019 using Google Forms. It involved 200 schoolchildren in grades 9-11 (15-17 years of age), 251 parents, 389 school teachers, and 220 healthcare professionals. Results: The survey data demonstrated the lowest subjective assessment of risks of the uncontrolled use of digital devices among schoolchildren (p≤0.05) and, at the same time, the highest prevalence of the considered risk factors among them. About 30% of the schoolchildren, 20% of parents and 20% of teachers underestimate behavioral risk factors of the uncontrolled use of gadgets (p≤0.05). I established the leading role of parents in forming the skill of long-term screen time in young people and noted low competence of healthcare professionals in issues of the safe use of digital devices and related components of a healthy lifestyle (using devices in poor lighting, inappropriate places and positions, lacking regular breaks, underestimating risks of low physical activity and eating less than 3 meals a day). I also found that teachers, being aware of safety requirements, comply with them but do not use this experience in their professional activities. Only 65% of schoolchildren and parents and 60% of teachers (p≤0.05) have skills of a safe screen use and take measures to preserve and maintain visual acuity. Conclusions: The survey revealed the importance of improving awareness of the population in issues of the safe use of digital devices, increasing the number of school subjects providing knowledge on this issue and contributing to the development of related healthy lifestyle components, and using all possible sources of transmission of relevant information.

Introduction. The process of involving children, adolescents and youth in the constantly developing information space is an objective reality. At the same time, the lack of monitored indices of the safety of electronic devices (ED) for the health of children and adolescents, the lack of a clearly built system of preventive measures require its development and improvement, which will reduce the risk of the digital information environment impact on the health of the younger generation. Materials and methods. The survey using a questionnaire, developed by specialists from the Research Institute of Hygiene and Health Protection of Children and Adolescents in 2017-2020, was used to collect data on the nature of ED using by schoolchildren and students in educational and leisure activities (1218 questionnaires). In 2017-2020, 805 schoolchildren and students from the Moscow gymnasium №12 and the Pirogov Russian National Research Medical University underwent an ophthalmological examination. Results. All the surveyed schoolchildren and students used ED. Analysis of the questionnaire data allowed us to determine the duration of continuous use of ED (computer, laptop, tablet, smartphone, etc.) by children, adolescents, and young people during school and vacation time. All categories of respondents both during the academic period and during holidays showed a high duration of continuous use of ED. Thus, the presence of a behavioral risk factor for the uncontrolled use of ED (long duration of continuous work with ED) was shown among all categories of respondents, which may cause the development of eye diseases. The analysis of the results obtained revealed significant negative values of the correlation coefficients between students’ visual acuity and the duration of their continuous use of both stationary (computer) and mobile (smartphone, tablet) ED. Discussion. The introduction of these preventive measures into the daily routine and lifestyle of children, adolescents, and young people will help prevent visual acuity disorders. Conclusion. It is necessary to introduce hygienic rationing of the frequency and duration of the possible influence of ED not only during the educational process but also in leisure time to increase the awareness of parents and the degree of their control over the use of ED. To elevate awareness of all ED users’ categories it is necessary to intensify work to promote the rules for the safe use of ED and related foundations of a healthy lifestyle and self-control over ED use. In connection with the development of the digital educational environment, it is advisable to improve the hygienic standardization of text information in electronic publications for children, adolescents, and students. To prevent the symptoms of eye fatigue, it is advisable to limit continuous work with a bright screen (no more than 60 minutes), followed by a break of at least 15-20 minutes, not related to viewing the illuminated screen, in compliance with the recommendations for relieving stress from the visual analyzer.
