Objectives to reveal cause-and-effect relationships in the system "air pollution morbidity of the population" in a large industrial city. Material and methods.The dynamics of the pollutants concentration, such as formaldehyde and benzopyrene, through the period of 20152017 was analyzed in relation to the indicators of the morbidity of the respiratory system in the population of Samara. In particular, the study focused on the ratio of allergic rhinitis and asthma cases and the concentration of the formaldehyde and benzopyrene. Results.The incidence of respiratory diseases and the general morbidity increased both among children (by 46.7%) and adults (by 11.4%). There was the causal correlation between the effect of benzopyrene on the development of allergic rhinitis and bronchial asthma in children(r = 0.57 and r = 0.76) and in adults (r = 0.45 and r = 0.51) in Samara. The significant differences between the level of the pollutants and the frequency of the respiratory system diseases were registered in children and adults in different areas of Samara. Discussion.As a result of the increase of the maximum allowable concentration (MAC) of formaldehyde in atmospheric air, this pollutant has now ceased to be a priority. The revealed negative correlations point to the absence of an adverse effect of formaldehyde on the development of allergic rhinitis and bronchial asthma in both children and adults in Samara. Conclusion.According to the results of the study, the preventive measures aimed at reducing the impact of main air pollutants on the health of children and adults in Samara were suggested. Their implementation is possible by the immediate informing of the executive authorities to ensure they can make timely management decisions to improve the quality of the environment.

Studies have found that regardless of the place of residence, with an increase in the severity and intensity of the labor process in obese medical workers there is a marked decrease in the quality of life. The working conditions have an impact on the growth of morbidity in obese doctors.

INTRODUCTION: On the basis of competent statistical materials updated in accordance with the All-Russian Classifier of Types of Economic Activity (ARCoToEA 2) and ICD-10, a retrospective analysis of occupational morbidity in different types of economic activity and professional cohorts of the industrial sector of the Saratov region in 20092019 was carried out by generally accepted methods. AIM: This a comprehensive analysis of current trends and trends in the prevalence, dynamics and nosology of occupational morbidity of workers in the industrial sector in the context of types of economic activity on the example of the Saratov region. MATERIALS AND METHODS: The information base of the study was presented by statistical materials of Rosstat, the Rospotrebnadzor Department for the Saratov Region and the Ministry of Labor and Social Protection of the Saratov Region, updated by us in accordance with ARCoToEA 2 (version OK 029-2014). A retrospective epidemiological statistical analysis of occupational morbidity for the period from 2009 to 2019 was carried out. RESULTS: During the analyzed period, the number of people employed in the industrial sector of the regions economy decreased by 17.5% from 380.3 (2009) to 313.7 (2019), while the level of primary occupational morbidity decreased by 2.7 times from 0.68 to 0.25 per 10,000 workers against the background of an increase in the share of workers in harmful working conditions in the extraction of minerals (+27.9 percentage points), in construction (+16.8 percentage points) and manufacturing industries (+11.5 percentage points). The main risk factors for occupational morbidity were physical effects (noise, general and local vibration), pollution of the respiratory zone with industrial aerosols, and the severity of the labor process. The nosological structure of the accumulated occupational morbidity was mainly represented by sensorineural hearing loss (SHL) 48.7%, vibration sickness (VS) 15.4%, radiculopathy 9.6% and chronic dusty non-obstructive bronchitis (CDNB) 7.7%. Workers in manufacturing industries were mainly identified by SHL (32.4%), VS (17.2%), CDNB (12.4%); transport workers SHL (77.2%), radiculopathy (10.9%), VS (7.9%); those employed in oil and gas production SHL (35.7%), VS (28.6%), radiculopathy (17.9%); in construction VS (22.2%), SHL (18.5%), radiculopathy (18.5%). CONCLUSION: The results of the identification of deterministic nosologies of the occupational morbidity, characteristic of certain sectors of the economy and professional cohorts, should form associative diagnostic alertness during regulated medical examinations and serve as a scientific basis for the development of targeted regional programs to promote health in the workplace.
