Increasing academic load, intensification of academic activity, use of not priorly certified innovative pedagogical technologies have been linked with steadily declining health in students. This is how a search for new effective methods of formation, strengthening and increasing health of students is initiated. An important task is to provide for scientific justification of the innovative approach to health control in students from general educational institutions of various types. Heavy academic activity, research of the functional condition of the central nervous, respiratory and cardiovascular systems were assessed in lyceum and school students in Grades 9–10. Students from an ‘at‑risk’ group had their psychophysiological condition corrected; the effectiveness was assessed by comparison of psychophysiological indicators before and after the session. When intensive academic activity is involved, adolescents from a lyceum had better operational indicators of the central nervous system, and functional indicators of the respiratory system as compared with schoolchildren. Students from the both groups had reduced biological, social and psychological adaptation. Sessions of functional biocontrol resulted in the increased number of those examined with normal working capacity and satisfactory biological adaptation against the background of a decreasing number of adolescents with a high level of psychoemotional stress. Functional biocontrol is an effective correction method of psychophysiological state of those educated. This determines the necessity of its use in educational institutions of various types.

Socio-economic outcome of long-term SARS-CoV-2 pandemic poses a major health risk to children. A high number of neurological disturbances and nutrition-associated problems are reported. Hygiene is one of the most important measures to avoid the novel coronavirus infection. Children and adolescents commonly constitute a special population, as disease severity in this group significantly differs from that in middle-aged and senior groups. Lockdown and transition to remote learning result in numerous reasons for emotional stress such as a dramatically altered way of life and education, and an important reduction of physical activity. The basic hygienic measures for children and adolescents included lockdown and transition to remote learning. An altered way of life caused strong emotions and poor academic achievements. As time passes, based on numerous statistical data, we can conclude that the role of children in the infection transmission and spread is insignificant. In spite of doubtful effectiveness of transition to online learning and an abundance of negative consequences for children’s mental health, some authors report that closure of schools resulted in a reduced number of those affected and decreased mortality rate. Hand hygiene is a very important way to prevent the spread of infections. Hygiene promotion aimed at children and adolescents is lacking during the pandemic, as explanatory talks are mainly given by parents.

The development of information technologies, their availability for every family, the transition to distance learning could not but affect health status of schoolchildren. In the past year, amid the spread of the new coronavirus infection, the time that schoolchildren spend with gadgets has significantly increased. The relevance of this study is determined by the evaluation of the ever-increasing and, as a rule, negative impact of computer technologies on the health of schoolchildren. The study aimed to investigate the features of the effect information technologies have on the well-being of high school students and to analyze the role teachers play in popularization of healthy lifestyle and reduction of the degree of influence of information technologies on health of modern schoolchildren.

The growth of eye disease incidence in the juvenile population amidst increasing visual load, which, among other factors, results from the use of electronic devices (ED), outlines the search for effective preventive measures, geared towards preservation of health of young people. The study was aimed to assess the impact of life activity upon exposure to digital environment on the organ of sight in schoolchildren and college students. The study was carried out in 2017-2020 at Dolgoprudny gymnasium and Pirogov Russian National Research Medical University. A total of 805 schoolchildren and college students underwent ophthalmologic examination. Accommodative response was registered with Speedy-K Ver. MF-1 autorefractor keratometer (Japan). A standardized questionnaire, tailored by the authors to meet the requirements of the study, was used to assess the regime for the use of ED by students. Inclusion criteria: schoolchild, college student, ophthalmologic examination data and submitted informed consent available, correctly completed questionnaire. Statistical processing was performed using the Statistica 13.0 software. All students were the ED owners. Only 9.9% of primary school students, 2.7% of secondary school students, 1.9% of senior secondary school students, and 0.9% of college students did not use ED every day. Significant negative correlation was revealed between the students’ vision acuity and the daily total time of using the ED, as well as the duration of the ED continuous use (р≤0.05). Accommodation weakness was detected in 88.76% of students with early stage of myopia; accommodative response close to normal was less common (11.24%). The increase in daily total time of using the ED by 2 hours and more results in higher prevalence of functional vision problems (p≤0.05), and the trend of increasing the number of high myopia cases. The data obtained define the need of improving the students’ hygiene training starting from the preschool age.

Adaptive capabilities of young people enrolling at higher education establishments differ from person to person. Depending on the level of these capabilities, a new student may see his/her quality of life deteriorating and a variety of diseases developing. Against this background, investigation of the dynamics of students' adaptation to studying at a higher educational establishment acquires special urgency: the results of such an investigation would enable designing an effective psychological support program for such students. This study aimed to investigate how the quality of life of students changes as studying at a higher education establishment alters their degree of adaptation and lifestyle. The report compares the studied degree of adaptability and quality of life of the same group of students in their first and third years. By design, the study was prospective continuous; it involved 120 students. M. Gavlinova's two-factor questionnaire (SA, social-ANS) enabled study of the degree of adaptability. As for the quality of life of the participating students, it was registered with the help of the SF-36 questionnaire. Lifestyle of the students was assessed relying on the questionnaire designed to uncover the person's attitude to smoking, alcohol, drugs, physical culture and sports. The results obtained enabled development of recommendations aimed at identifying students running risks of maladjustment and illnesses with the aim to render such students targeted medical and psychological assistance and adjust the sanitary and epidemiological conditions of studying.

Wide use of computers, information and communication technologies and gadgets in industry and society unlocks creativity, refines logic, stimulates analytical and research skills, makes work much easier, and allows many types of activities to be performed remotely. But despite their indisputable advantages, information technologies have a downside. The negative impact of computers and electronic gadgets on the cognitive, emotional and mental states, the gastrointestinal tract, vision and the musculoskeletal system have been proved. Children are particularly sensitive to the negative effects of IT. This study provides concise information on some IT-associated health conditions (IT-associated morbidity) and proposes some measure to minimize the negative effects of IT on children’s health.

In the past few years, the number of elderly people has been growing in Russia. Every fifth retired person does not resign and continues to work. The situation with employees that have already reached the retirement age is distinctly special in the country's higher education establishments. Therefore, the task of studying the peculiarities of health of higher school professors that have already passed the retirement age threshold or are approaching it is an urgent one, the purpose of such a study being prolongation of the "healthy old age". It is necessary to factor in gender specifics, since, according to the statistics, men run greater risks of developing chronic non-communicable diseases than women. The purpose of this study was to investigate the gender-related peculiarities of the physical condition and the rate of aging of medical university professors of pre-retirement and retirement age with the aim to develop measures enabling such employees to maintain a high level of working efficiency. The study involved 169 teachers aged 55-70. A set of anthropometric measurements was taken. The participants had their blood pressure measured, level of physical condition and their adaptive potential assessed. The rate of aging and biological age were calculated for all the participants with the help of A.G. Gorelkin and B.B. Pinkhasov's formulas. The study revealed significant differences in most morpho-functional status indicators signaling of the greater cardiovascular system disease risks run by male teachers compared with their female peers. However, female participants presented significantly more cases of obesity, which explains the revealed differences in the rate of aging that was higher among women.

This article focuses on approaches to implementing the principles of P4 medicine, specifically, stimulating prevention-based thinking among students of faculties of general medicine and pediatrics. Below, we describe a pilot approach to teaching hygiene that was implemented at the Department of General Hygiene (Kazan State Medical University). Considering the gnoseological role of empathy, we designed an interactive workbook for students taking a course in Hygiene. The workbook allows the student to engage in empathic interactions and discourse about the studied subject with the teacher and peers. After the course, the students were surveyed; their degree of engagement in the learning process and their expectations were evaluated. The respondents rated their interest in Hygiene before starting the course as 5.6 and 5.7 points on the 10-point scale (for the traditional and innovative courses, respectively). During the course, the score increased to 5.8 and 8.6 points for the traditional and innovative courses, respectively. Our pilot project demonstrates the need for reviewing the strategy of teaching hygiene and prevention-related disciplines at clinical faculties and including the principles of P4 medicine in the medical curriculum, thus allowing the student to effectively perform their professional duties in primary healthcare.
