The relative age effect (RAE) has been well studied in adolescent and adult soccer players; however, less information has been available about children engaged in regular soccer training and the role of performance. Thus, the aim of the present study was to examine the prevalence of RAE in children and adolescent soccer players, as well as the role of age and performance. Russian soccer players (n = 10,446) of various ages, playing positions and performance levels were examined for their date of birth. It was observed that RAE was widespread in Russian soccer teams of all age groups. RAE was most pronounced in children teams of the top tier Russian soccer academies and junior Russia national teams, where the proportions of soccer players born in the first quarter were 43.9% and 39.8%, respectively, whereas those born in the fourth quarter of the year were 7.7% and 6.3%, respectively. In top tier soccer academies, RAE did not vary by age group. In the middle tier soccer academies, RAE was less pronounced. It was still prevalent in the junior teams of the top tier clubs of the Russian Premier League, where 14.3% of the soccer players were born in the fourth quarter of the year compared to 42.9% born in the first quarter of the year. RAE can be observed in the top tier Russian adult teams as well, although it is less pronounced there. In summary, RAE is highly prevalent in Russian children and junior soccer and is associated with the level of competitiveness. At the same time, the proportion of players born in the fourth quarter of the year is higher in adult teams than in junior and youth teams, which is most likely due to the wider selection of players, not limited by their age and place of residence. In junior teams, RAE results in a bias towards selection of players who are more physically mature, whereas children who may be more talented but are less developed due to their younger chronological age tend to be overlooked.

An expert analysis of lectures and reports at the XIX Congress of the European Union of School and University Medicine and Health (Belgium, Leuven, 2017) presents issues of school and university medicine: modern approaches to assessment of children’s health; ensuring equal access of all children, adolescents and youth to medical care during the period of education in accordance with the Convention on the Rights of the Child, regardless of socioeconomic status, ethnicity and cultural level; the effectiveness of health services, friendly to students, assessment of medical care for students quality; the role of parents in organizing medical care for students; the role of the media in shaping the identity of children in the process of growth and development. The concept of «positive health» focuses on positive and healthy aspects, and not only on medical treatment. The main elements of «positive health» include: physical functioning, daily routine, mental health, social activity, intentions, quality of life. In Europe prevails a program approach to prevention based on targeted work with relevant groups of children and adolescents. There is a need for assessing the impact of environmental factors, access to care and education for children with special needs, providing preventive care for vulnerable children, infants and their families, promoting healthy behavior among students, special approaches to providing mental health to students through available health services and various programs, incl. based on the welfare of children and interventions in the early stages of emotional problems considering risk factors that can be identified in educational institutions. Modern main directions of research in the field of health protection and promotion of students in educational organizations are due to large-scale changes in the environment (pronounced urbanization), the new way of life and quality of life for children and adolescents, their life conditions in a rapidly changing world combined with unfavorable trends in health and development indicators of the growing up generation of Russians.

The topicality of the research lies in the fact that the challenges of the last decades, especially the last few years, caused the growth of crime, violence, extremist and terrorist sentiments, and extensively involved youth in these processes. For these reasons, there is an acute need to study aggression and social aggression, especially the aggressive behavior of youth. An interpretive comprehension of these phenomena by social philosophers is important because aggression, in any form, is a social construct, is formed and manifested in social interaction; and the use of philosophical methods allows studying all the factors that influence its formation: political, economic, social, psychological and others. In this paper, we present a review and analysis of various approaches to understand human and social aggression, their generalization, and develop a general and comprehensive point of view relate to their nature and determinacy. The methodology of the research is based on the universal laws governing the development of nature, human society, and thought: dialectical synthesis, the transformation of quantity into quality, and the identity of opposites; the philosophical theory of determinism; and system-activity approach. The leading theoretical methods to study this issue are concerned with the content analysis of scientific papers relevant to the research problem, and, hence, consider the factors associated with the formation and manifestation of aggressiveness in general and social aggression in particular. The paper provides a definition of the phenomenon of social aggression considering it as a system of aggressor's attitudes and behaviors in the interaction, his intention of inflicting damage or other unpleasantness upon another individual, the aim to create more efficient (dominant) terms of interaction and activity, and/or cause damage to the target victims. Using system-activity approach to characterize the phenomenon the following features have been distinguished: a specific way of organizing activities, rationality, a temporal duration, purposefulness, practicality, introductory nature, a possibility of control and self-control, invertibility and duality caused by human consciousness as the only factor. The authors hope that the materials of the article might be of theoretical and practical value for developing programs aimed at the prevention of aggression, especially social youth aggression, and bring the process of social adaptation and socialization of young people back to the normal state, thus reducing the risk of destructive tendencies.
