In the article there are presented the results of physiological and hygienic evaluation of studies in kindergarten with the use of educational games on an electronic PC tablet. The study involved 44 foster-children. In one of the groups children in the classroom used the interactive game software on electronic PC tablets «Samsung», the same time while working with the PC tablet did not exceed 10 minutes, in the other - the classes were held traditionally. There were investigated the state of health, psychosomatic and psycho-emotional state of children, determined their functional readiness for systematic training in school, mental performance, the functional state of the central nervous system (CNS) by simple visual-motor reaction (SVMR) and reactions to a moving object (RDO). Developing of game sessions with the use of electronic PC tablets for 10 minutes were established to contribute to the activation of the central nervous system and increase in children resistance to the development of fatigue.

Background: In contemporary conditions of digital transformation of education, the medical community, teachers, and parents are concerned about health effects of electronic learning tools in children. The emergence of new types of digital tools necessitates studies of related fatigue of schoolchildren in the dynamics of learning. A questionnaire-based survey of pupils aimed to establish their main complaints attributed to the use interactive panels, the most common type of educational boards in the classroom, helps identify and analyze weaknesses from the point of view of health maintenance in organization of the educational process. Objective: To study specific health effects of interactive panels used in the classroom in fifth-year pupils. Materials and methods: We conducted a questionnaire-based survey of 130 schoolchildren aged 11 years to establish their self-rated health, visual functions, risk factors and educational experience related to the use of interactive displays. Data processing was carried out using nonparametric methods of statistical analysis; relative risk values were established according to the rules of evidence-based medicine. Results: Some pupils, especially those with vision impairment, had complaints indicative of general and visual fatigue following the exposure to interactive panels. Inappropriate or excessive use of the interactive display in the classroom increased the frequency of such complaints. Conclusion: The reported adverse factors including bright light from the display, small and fuzzy image, rising temperature in the classroom, etc., defined preventive measures to be implemented for ensuring safe learning conditions.

Background: The innovative form of organizing schooling in the mode of dynamic postures providing for alternation of standing and sitting postures at each lesson is implemented in order to prevent detrimental health effects of the long-term stationary sitting posture, reduce static and educational fatigue, preserve and strengthen health in educational institutions. Our objective was to assess the health status of primary school children studying in dynamic postures. Materials and methods: We assessed the health status of 174 pupils aged 7–10 in the first to third grades of primary school studying in the mode of dynamic postures. The health data was obtained from their personal medical records. The assessment was carried out in accordance with the comprehensive methodology for assessing health of children and adolescents based on the 10th revision of the International Statistical Classification of Diseases and Related Health Problems. Physical development was measured using regression scales. Results: We established that visual impairment (137.9‰) and musculoskeletal disorders (109.2‰) ranked highest in the structure of functional disorders (FD) among the first to third graders. The prevalence of functional disorders of the circulatory and respiratory system was 86.2‰ and 80.5‰, respectively. Musculoskeletal conditions dominated in the structure of chronic diseases (63.0%), the prevalence being 293.1‰. These were followed by diseases of the skin and subcutaneous tissue and gastrointestinal diseases with the prevalence rate of 46.0‰ each. The total prevalence of functional abnormalities among the primary school first to third graders was 500.0‰ while the prevalence rate of chronic diseases was 465.5‰. Normal physical development was observed in 82.9% of the subjects. Overweight and obesity were detected in 11% and 0.6% of the children, respectively, while underweight, small and big height were measured in 3.1%, 1.8%, and 0.6% of the children, respectively. Conclusions: The comparative data analysis helped establish lower disease prevalence rates among the children studying in dynamic postures compared to those studying in the seated position. Our findings may serve as a scientific substantiation of efficiency of using the dynamic posture regime in order to maintain and improve health of schoolchildren.

The objectives of reforming the Russian education open up new possibilities for organizing the educational process on the basis of the shaping of principles of a healthy lifestyle embodied in standards of preschool education. The study was conducted in 8 Moscow kindergartens. The questionnaire survey included 437 parents of children of young preschool-age (3-4 years) and older preschool-age (5-7 years). The vital activity of modern preschool children was established to be characterized by the elevated of the static and emotional load against the background of deficiency of physical activity due to the increased use of gadgets and watching television, visiting other classes for preparation for school. Failure to comply with a rational mode of the day in the family has a negative impact on the health status of preschool children. Familiarizing parents to a healthy lifestyle, the optimization of mental and physical loads, the increase in the physical activity for children are the priority areas in health promotion work with preschool children.

Introduction. The foot is the foundation of health, performing essential functions for ensuring human life. The foot’s disorders and deformities significantly limit the body’s capabilities and reduce the quality of life, starting from childhood. A necessary condition for prevention is the assessment and control of the feet, including educational activities. The importance of such studies increases with hygienic studies of innovative forms of education. Materials and methods. The study involved 220 7-9 year children (104 boys and 116 girls), studying in an innovative form of education that implements the mode of dynamic postures sitting at a table and standing at a desk. Plantographic studies were carried out using a copy print of the trace “Bauerfiend” (Germany). For the analysis of plantograms, the Striter method was used. Various symmetrical (two-sided) and asymmetric (one-sided) combinations of right and left foot states were evaluated (11 variants in total). Results. The features of the prevalence of symmetrical and asymmetric forms of states of the longitudinal arch of the foot in students aged 7-9 years are determined. Symmetrical forms of foot conditions were found in 64.1% of children, asymmetric-in 35.9 %. The prevalence of normal bilateral arch of the foot was observed in only 28.6 % of children, flat feet-in 13.2 %, flattening-in 17.3%, elevated arch-in 4.1 %, hollow foot-in 0.9 % of children. In the course of training from the 1st to the 3rd grade in dynamic poses, positive dynamics of the feet states was noted 1.8 times more often than unfavourable. The features of the dynamics of the state of the feet were revealed: the frequency of flat feet did not change, the increased arch of the right foot decreased by 3.5 times, the left - by 11 times; the flattening of the right foot increased by 1.6 times, the left foot - by 1.8 times. It is pointed out that it is necessary to identify asymmetric states of the feet that have a prognostic value in the formation of disorders of the musculoskeletal system in children, including in educational activities. Limitations. The criteria for inclusion of children in the study were the age from 7 to 9 years and the absence of acute diseases at the examination. Conclusion. The obtained data should be considered when conducting and analyzing the results of foot examinations in the process of preventive medical examinations of the child population.
