Symptoms of chronic cardiometabolic disease such as hypertension, hyperglycemia, dyslipidemia and inflammation, as well as type 2 diabetes, are becoming more common in obese adolescents. Physical inactivity, lack of sufficient physical activity among young students, the availability of sugar-containing products, sugary drinks and fast food, the high cost of healthy eating, aggressive advertising of unhealthy foods, economic difficulties, the influence of the social environment are factors in the growth of BMI and obesity among students. University students are characterized by the lack of a balanced diet, with habits such as snacking as the main meal, consumption of drinks with artificial sugar, fruit juices, and rare breakfast. Students have high consumption of unhealthy foods that contribute to weight gain and obesity: jerky, smoked sausages, hot dogs, white bread and baked goods, butter, fried foods and energy drinks, alcohol, especially by male vocational school students. Vending machines installed on student campuses provide quick access to unhealthy, sugary foods and drinks, contributing to poor nutritional status and obesity in students.

The widespread use in today's world of radioactive sources d in energy, medicine, engineering and construction, for contaminant tracking and food sterilization increases the likelihood of accidental exposure. The use of ionizing radiation and radioactive elements can directly or indirectly cause life-threatening complications, such as oncopathology, radiation burns, and impaired immunity. Pollution of the environment with radioactive elements and depletion of the ozone layer also contribute to an increase in the level of radiation exposure. To protect the health of the population living in contaminated areas and consuming locally produced products, it is necessary to organize a system for monitoring radioactive damage, as well as special anti-radiation protective measures in the field of agriculture and forestry, hunting and fishing, and providing the population with food.The purpose of the study is to analyze modern scientific data on the effect of ionizing radiation on reproductive function and modern approaches aimed at correcting its violations.Bibliographic, information-analytical methods and methods of comparative analysis were used.

The dynamics of the main indicators of childhood disability is important for determining guidelines in the medical, social, and economic directions of the development of society and the state. In the course of the analysis, it was revealed that during the period of the introduction of mandatory medical examination of the child population in the Republic of Azerbaijan, the increase in the number of children with disabilities in 2019 compared to 2014 was 16.1%. However, the number of children with disabilities with a primary diagnosis decreased by 17.7%. The greatest decrease in the level of primary disability was observed in the following types of diseases: diseases of the circulatory system – by 86.5%; tuberculosis – by 67.4%; respiratory diseases – by 66.8%; injuries, poisoning and some other effects of external causes – by 64.7%, etc. At the same time, an increase in primary disability among children was noted for such diseases as: mental and behavioral disorders – by 70.9%; diseases of the ear and mastoid process – by 52.6%; congenital anomalies (malformations), deformities and chromosomal disorders – by 38.6%, as well as a number of others.

The article presents scientific evidence that new neurons from progenitor cells throughout life in almost all animals with a nervous system are an integral component of neuronal ontogenesis and plasticity.It has been shown that there are neural stem cells in the brain that give rise to adult neurogenesis, occurring primarily in the dentate gyrus, a subregion of the hippocampus important for learning, memory, and emotion. With age, there is a decrease in adult neurogenesis, which is associated with a decrease in cognitive functions. Newly formed neurons and «immature» neurons together constitute a potential reservoir of young cells («brain reserve») that can be used to prevent aging and/or delay the onset/reduce the impact of neurological disorders.The possibility of using neurogenic processes for therapeutic purposes to reduce pain and improve the quality of life of patients is implied.

Adolescence is considered a vulnerable period of life due to the influence of factors that potentially contribute to the formation of unhealthy eating behavior. At the same time, the role and importance of healthy nutrition, as well as the process of forming habits and skills of good nutrition, are especially important for adolescence and adolescence, taking into account their fertility potential.Significant factors influencing the formation and changes in the eating behavior of adolescents and youth are indicators of the economic and social development of the country, place of residence, the level of income of the population, including family income, the level of education of parents, the opportunity to engage in physical education and sports, advertising pressure, including including television and on the Internet, the state of society and industry, the degree of psychological well-being in the family and school environment, the level of complexity of personal and communication problems of young people. In order to improve eating behavior and health, reduce the consumption of unhealthy foods among adolescents and young people, systemic actions are needed that target various eating habits. It is important that the activities take into account the emotional, socio-economic and cultural aspects of the life of young people in different countries.
