Sarkuland Kenkiyak settlements are located in the Aktobe province, at18-20 km from the oil and gas producing field "Zhanazhol", in the northwest region of the Republic of Kazakhstan. To evaluate the exposure of the adult male and female population living in Sarkul and Kenkiyak settlements, a single medical study was conducted. The nonparametric method of the Spearman correlation analysis was performed between the mean concentration of substances exceeding the Maximum Permissible Concentration and the classes of newly diagnosed diseases. Selection and analysis of air samples was carried out according to the developed research protocol; the qualitative-quantitative analysis was carried out on the Gas analyzer HANK-4 apparatus. Significant pollution of atmospheric air by carbon monoxide, benzapyrene, dust and phenol were identified in places. Correlation dependencies between these pollutants of air and the diseases of the population revealed as a result of medical examination are established, as a result of diseases of the circulatory system, ear and mastoid process, nervous system and digestive organs; between the concentration of carbon monoxide and diseases of the circulatory system, the digestive system, the genitourinary system and the musculoskeletal system; between nitric oxide and diseases of the digestive system and the circulatory system; between benzopyrene and diseases of the digestive system, the genitourinary system and the nervous system.

BACKGROUND: The frequency of breakfast consumption as a determinant of fruit and vegetable intake among children and adolescents has been poorly investigated. AIM: In this article, we examine whether irregular food intake is associated with fruit and vegetable intake among children and adolescents. METHODS: We use a separate analysis, with special attention being paid to the potentially changing effects of gender and age. The methodology of health behavior in school-aged children is used. RESULTS: The obtained results show that irregular breakfast consumption among children and adolescents is associated with a low frequency of fruit and vegetable intake and that gender and age can play a decisive role. Various associations observed in different age and gender groups indicate the importance of a separate analysis of fruit and vegetable intake and types of food. CONCLUSION: The results emphasize the importance of encouraging regular food intake while trying to increase fruit and vegetable intake among children and adolescents.

The formation of the health of adolescent children is carried out under the influence of many risk factors, including non-medical determinants: lifestyle, socio-economic, household factors and living conditions. Conducting epidemiological studies to identify the leading risk factors for the lifestyle and quality of life of adolescents is currently consistent with the basic directions of development of preventive medicine. Aim. Analysis of literature data, leading factors, the impact of social determinants on the health and well-being of children and adolescents. Material and methods. The choice of publications was made according to keywords that reflected between the indicators of the health of children and adolescents and the factors that influence them. Assessment of the influence of social determinants on the health of children and adolescents made it possible to prepare comprehensive measures to improve the health and health of children and adolescents. Conclusions. In the literature review, the social conditions studied have a decisive influence on the formation of the lifestyle, health and well-being of children and adolescents. Keywords: сhildren, adolescents, social determinant.
