In recent years, the problem of youth health preserving does not lose its relevance and occupies significant place in biomedical and psychological-pedagogical research. Bioinformatics technologies implement methods that allow administration of biological objects data. The main goal of bioinformatics - contribute to understanding of biological processes. It focuses on creating and applying intensive computational methods to achieve this goal.
The man and his body, acting as biological object is open system in which there is highly organized system of perception, sorting, distribution information from environment. This ensures the organizational, structural and functional development of biological object, which can be viewed as complex structure of multistage hierarchical sequence of interacting systems and subsystems that are in close contact with the environment (Kelina, 2011, p. 164). Human health is formed in inextricable unity of biological, psychological, social and environmental factors. Figure 1 shows the graphical representation of health as bioinformatics object.

Behavioral, professional and other components of yuoth lifestyle are complex biosocial system. The definition of various states in description of body functional systems of people with different lifestyle features is an actual problem of bioinformatics (Bagnetova, 2012).
The relevance of the conscious attitude of young people to health is due to several reasons: first, the health of the younger generation is of medical and social nature, because in the future it will determine the quality of human and economic potential of the country and its defence potential. Secondly, the health of adolescents is crucial for the reproduction of the population and the health of future generations. Thirdly, an important characteristic of recent years is the health deterioration of younger generations.
The World Health Organization (WHO) defines “health” as a state of not only absence of disease and physical defects, but complete well-being: physical, social, spiritual. Health is “...a qualitative prerequisite for the future self-fulfilment of young people, the ability to create a family and childbearing, complex educational and professional work, social, political and creative activity” (Denisova, 2015: p. 67).
Health is the most important life value; longevity, youth preservation, self-fulfilment largely depend on it (Boyak, 2016: p. 142). The research of Kozyreva P. M., Nizamova A. E., and Smirnov A. I. show that health is closely correlated with a life of happiness. Thus, the share of happy people is 82% in the group of respondents with very good health and only 17% among respondents who assess their health as very bad (Kozyreva, 2016: p. 71).
The concept of “attitude to health” is complex. It includes several aspects: cognitive (ideas, opinions, beliefs and knowledge about health, healthy lifestyle), emotional (feelings and emotions related to health, health as a value), behavioural (actions and activities aimed at maintaining health or eliminating pain) (Moiseeva, 2018). Thus, a person's attitude to health is determined by objective and subjective factors and is manifested in actions verbally reflected in people's opinions and judgements on the factors affecting their physical and mental well-being. Self-assessment of physical and mental state acts as a real indicator of human health, as there is a high degree of compliance between self-assessment and objective health status.
It should be noted that the perception of health as a source of existence in modern socio-economic conditions has two meanings. First, certain categories of respondents interpret health as physical capacity rather than the presence or absence of specific symptoms of a disease. Second, the research showed respondents' assessment of their health from the point of view of their psychological possibilities. Many Russians see health as a condition not preventing them from performing their everyday activities. American researchers highlight a similar perception of health and disease. That is, people tend to view their health as one of the most important resources that allow them to exist in the modern world (Sochnev, 2007).
