Abstract: Objective: To investigate the correlations between screen time, outdoor activity time, and the physical health of preschoolers, so as to provide suggestions for formulating interventions to prevent myopia and obesity in children. Methods: A cross-sectional study was carried out in Shenzhen city. A representative sample of5,226 preschoolers and their caregivers were recruited by proportional stratified cluster sampling. Data were collected by the Chinese early human capability index (CHe HCI), children's media use in daily family life questionnaire, and body mass index (BMI). Linear regression and binary logistic regression models were used to analyze the effects of screen time and outdoor activity time on physical health of preschoolers. Results: Preschoolers spent (110.30 ± 90.67) min/d on screen and (61.11 ± 41.16) min/d on outdoor activity. 5. 47% of preschoolers were overweight. Screen time negatively predicted preschoolers ' physical health, while outdoor activity time positively predicted preschoolers ' physical health of CHe HCI. There was no significant association between outdoor activity time and BMI of preschoolers. Conclusion: This study suggests parents might need to reduce preschoolers' screen time and increase outdoor activity time to promote the physical health development of preschoolers.

Abstract: This report analyzes the risk of decreasing physical and mental health of adolescents. The research situation in which the rapid development of technologies outpaces the research protocol and methods of psychological diagnostics being developed by scientists to study an objective picture of adolescents' functioning and development in the digital environment are discussed. Assessing the negative effects of the impact of the digital environment on the developing personality requires a particular set of research tasks. Internet overuse refers to excessive time spent online at the expense of other things. Such a behavioral addiction, according to DSM-5, is currently considered a direct threat to the psychological wellbeing of adolescents. PsychoDiagnostic Tools and/or scales traditionally used for diagnostics of various aspects of internet addiction were employed. We used 15 internet addiction tests as empirical material for an overview of the typical criteria of internet addiction. An analysis of the PsychoDiagnostic tools shows the criteria most likely to pose a threat to mental and physical health. The symptoms of internet addiction are: 1) social isolation; 2) emotional problems (depression, anxiety, irritability, etc.); 3) depression / apathy; 4) lack of self-regulation; 5) loss of control over their own behavior. The study results can help create a heuristic model for the study of internet addiction among adolescents, taking into account the research tasks, age of respondents, environmental and individual psychological factors. The pragmatic significance of the results is the possibility of their applicaiton in the design of psychological programs to address teen internet use.

Abstract: The purpose of this work was to analyze morphofunctional indicators of physical fitness in groups of Mongolian children and adolescents with different levels of physical activity. The results of a comprehensive survey of 3,519 boys and 3,617 girls aged from 8 to 17 years living in Ulaanbaatar were used. Children and adolescents were divided into 2 groups: athletes and controls. Greater values of the total body dimensions in athletes indicate that, under the influence of physical loads, the morphological status of the subjects begins to change quite early. By the end of the studied period, the intergroup difference reached its maximum, and was more pronounced in boys. As can be expected, the differences in functional indicators were much more pronounced: characteristics of respiratory and cardiovascular systems were better developed in physically active individuals (especially females). Hand grip strength was higher among athletes. Thus, positive changes in physical strength are directly associated with a higher level of physical activity. In terms of physical performance in non-athletes, agility, flexibility, speed and power endurance stabilized or worsened after puberty, while in athletes they continued to improve. The explosive muscle strength in athletes showed a steady improvement, while the controls were characterized by uneven and less intense increases. In general, the obtained results point to the heterochronic changes in motor coordination associated with the sex of the examined individuals. It can be concluded that systematic physical activity has a positive effect on body systems, significantly improving functional traits. Athletes are more adaptable to the environment in comparison to their less active peers. The greater range of differences in morphological traits in the groups of boys, and functional indicators in the groups of girls, can be interpreted in the context of the traditional way of life, with the typical gender stereotypes and roles present in Mongolian culture.
