Introduction. According to the World Health Organization, among young people, the prevalence of behavioral factors determining the violation of their health is especially increased. It determines the relevance of studying the influence of leading socio-hygienic, behavioral risk factors on the quality of life of modern adolescents. Material and methods. A survey of 15-17-year-old students of schools (n=489) and vocational college (n=292) was conducted. There were determined body mass index (BMI); type of eating behavior - according to the DEBQ questionnaire; quality of life indicators - according to the PedsQLTM4.0 questionnaire. A questionnaire was conducted to identify behavioral risk factors. The data is statistically processed. The significance level of the differences was determined by the Student’s criterion for parametric and the Mann-Whitney U-test for nonparametric features. The differences were considered significant at p<0.05-0.001. Odds ratios (OR) were calculated to establish risk factors. Results. Insufficient level of motor activity was a priority among adolescents. The associations of increased screen time with low physical activity among schoolchildren (OR=1.455) and college students (OR=1.251) were determined. The prevalence of smoking among school and college students was 23.6% and 33.8%, respectively. The components of irrational nutrition were determined; there was a decrease in the frequency of meals as they grew older, eating disorders. 28.5% of schoolchildren had disharmonious physical status. Among college students, body mass disorders were found in 26.2% of cases. The study of quality of life indicators in adolescents showed the highest scores on the scale of social functioning. The indicator of the final assessment of the quality of life was 79 points for schoolchildren, 73 points for college students. The probability of a decrease in the overall quality of life score among schoolchildren most depended on motor activity (OR=1.696) and prolonged use of gadgets (OR =1.550). Insufficient physical activity (OR=1.400) and tobacco smoking (OR=1.615) were statistically significant in the forecast of the probability of a decrease in the overall quality of life score among college students. Limitations. The study is limited to studying the influence of leading socio-hygienic, behavioral risk factors on the quality of life of schoolchildren and college students. Conclusion. Further research is needed to identify causal relationships between socio-hygienic, behavioral risk factors and indicators of the quality of life in adolescents, taking into account the active introduction of modern technological forms of education into the education system in schools and vocational colleges.

Objective to assess the risk of developing the burnout syndrome in medical workers under the influence of working conditions and psychological environment in the team. Material and methods. To evaluate the level of emotional burnout, 134 medical workers of medical institutions of the Saratov region were tested according to Viktor Boiko methodology, based on the study of the working environment and the labor process, as well as according to Fiedlers methodology of assessing the psychological climate in the team. Results. The study results testified the direct influence of the factors of the labor process that determine the class of working conditions on the risks of developing emotional burnout in medical workers. The 2.0 class of working conditions implies the risk of occupational burnout in 30.7% of doctors after five years of work. The 3.2 class of working conditions leads to burnout in 46.7% of doctors after five years of work. Discussion. The high degree of emotional burnout registered in medical workers in the course of this study was naturally determined by both the level of the class of working conditions and the level of the psychological tension in the team. The prognosis of burnout syndrome development in the teams with positive psychological climate is 20.0%, while in the teams with unfavourable psychological situation the risk of occupational burnout reaches 46.6%. Conclusion. The results obtained in the course of this study were used as the basis for the development of a method for predicting the risk of developing burnout syndrome in medical professionals.

The aim of this research paper was a sanitary-toxicological study of the effectiveness and safety of developed functional property products, such as chopped semi-finished products from chicken with wheat bran and shortbread cake with cottage cheese and sea buckthorn, in preclinical studies on laboratory animals. Methods — The effect of new products on the experimental rats was studied using physiological, biochemical, pathomorphological and histological research methods. As a result, it was discovered that the inclusion of foods with wheat bran and fresh sea buckthorn into the diet of experimental animals had a positive effect on the behavioral reactions of rats, the increase of appetite and the rapid growth of animals. Results — The improvement in the metabolic processes physiology of the studied rats was noted in the biochemical and morphological blood parameters. In the experimental group of rats where carbohydrates were partially substituted with cottage cheese shortbread cake and sea buckthorn, a significant decrease in the total bilirubin content was noted; the level of cholesterol in the blood serum of experimental animals from group which received chicken cutlets with bran was 1.4-1.7 times lower than the cholesterol content in animals of the control and other experimental groups. At the same time, statistically significant differences in the number of red blood cells, white blood cells, platelets and hemoglobin level, the activity of alanine and aspartate aminotransferases, alkaline phosphatase and amylase, the level of total protein and the creatinine content were not revealed in the group of experimental rats compared with the control group of rats, receiving a standard diet. The histological data showed that the liver structure of the experimental animals had a more pronounced beam and capillary structure compared with the control group, and the condition of the villi and epithelium of the small intestine showed the positive physiological effect of the studied herbal additives in food technology with functional properties. Conclusion — The research results allow us to conclude that the developed products are functional, intended for the systematic use in the composition of food rations by all age groups of a healthy population, which reduces the risk of gastrointestinal and liver diseases.

The materials on the study of the content of heavy metals and organochlorine pesticides in fish are presented. It has been established that the level of heavy metals and pesticides in fish is influenced by the territorial location of the pond production. Therefore, the content of lead, cadmium and mercury in the liver and gonads of carp was higher than the permissible values for fish growing in ponds located in the city limits near highways. The pesticides DDT and HCH were detected in the organs of fish in the territories of pond fish farming of farms. Residual concentrations of pesticides contained in fish did not exceed the maximum permissible levels. In order to safely consume fish grown near highways by the population, we recommend the removal of internal organs (liver and gonads) from fish products.

The article presents the results of the risk of developing the burnout syndrome in medical workers, taking into account the influence of hygienic working conditions and the psychological situation in the team. 134 medical workers with working conditions class 2.0, 3.1, and 3.2 were under observation. The ratio of the working conditions of medical workers to the corresponding class was established according to the Manual 2.2006–05 «Hygienic assessment of factors of the working environment and the labor process. Criteria and classification of working conditions». The methodological basis for assessing the level of emotional burnout of a medical worker in a team was a questionnaire developed by V. V. Boyko; the psychological situation in the team was assessed using a questionnaire by A. F. Fiedler. The conducted studies found that with the class of working conditions of doctors at the level of 2.0, the risk of developing emotional burnout after five years of work is 30.7 %. At the level of the class of working conditions 3.2, after five years of work, the burnout among doctors will reach 46.7 %. Against the background of a favorable psychological situation in the team, the probability of developing an emotional burnout syndrome was 20.0 %, with an unfavorable one, it increased to 46.6 %. The results obtained in the course of this study were used as the basis for the development of a method for predicting the risk of developing burnout syndrome in medical professionals in the first five years of work with a sensitivity of 78 % and a specificity of 68 %.
