Introduction. The work of many employees in the service sector is associated with a constant stay in a forced working position sitting at the computer for up to 60-80% of the time of the entire work shift, which leads to fatigue. The rate of fatigue depends on the specifics of work: it is much more likely to occur when working with monotony, muscle tension. An important role in the appearance of fatigue is also played by the attitude of a person to the work performed. The aim of study is to study the motor activity of knowledge workers in social service centers for the development of preventive measures aimed at reducing hypokinesia and hypodynamia during the work shift. Materials and methods. The following methods were used in the study: questionnaire and working day timing, calculation methods to determine whether the actual body weight corresponds to the ideal one using the Broka’s index and the Ketle’s index. The study involved employees of the integrated social service center "Raduga" in Bugulma. Results. An assessment of the motor activity of employees of the social service center of the population was made, and it was concluded that the problem of hypokinesia and hypodynamia is relevant and significant for employees of social service centers of the population both in their daily activities and during the work shift. Most of the employees showed an increase in actual body weight compared to the ideal one, which is to some extent due to hypokinesia and hypodynamia both during the working day and at home. Conclusions. Preventive measures aimed at compliance with the principles of rational nutrition and a healthy lifestyle, work and rest regimes, high-quality preliminary and periodic medical examinations are proposed.

The creation of conditions for improving public health and reducing risks from the effects of environmental and industrial factors are among the priority tasks in the development of the country's healthcare system in the long term [1, 2]. The purpose of the study is to conduct a hygienic assessment of the influence of the main pollutants (nitrogen dioxide, formaldehyde) contained in the ambient air on the health of the working-age population and to compare the identified nosologies with the causes of temporary disability of the population by classes of diseases in the period of 2008–2017 in Samara. Materials and methods. The main object of the study was atmospheric air. Sampling in the city was carried out at stationary posts located in all administrative districts of the city during the study period. A study of the registration form No. 16‑VN «Information on the Causes of Tempo rary Disability» of the Samara population for 2013–2017 was carried out. Results: The maximum concentrations of nitrogen dioxide were recorded in the Kirovsky and Promyshlenny regions in the period of 2011–2015 which averaged 0.042 mg/m3. Characterizing the distribution of formaldehyde concentrations by city districts in 2015 and 2017, it should be noted that it prevailed in the Kirovsky region compared to others (more than 40 %). The highest indicator of the air pollution index in Samara was registered in the period of 2008– 2013, which adversely af fected the health of the population. When assessing the spatial distribution of levels of atmospheric air pollution with nitrogen di oxide, its highest concentration was recorded in places of vehicles concentration and in the locations of fuel and energy enterprises and industrial plants in Samara (mainly Promyshlenny and Kirovsky regions). Conclusion: The priority diseases caused by exposure to air factors (nitrogen dioxide, formalde hyde) are respiratory diseases and malignant neoplasms. It should be noted that these diseases can occur in the adult working-age population both as a result of exposure to environmental factors and as a result of work in industries with harmful and hazardous chemical factors. Ethics. The study was conducted in compliance with all norms and principles of modern medi cine. The research is reliable, objective, and the information is provided in full. It complies with the Code of Ethics of the Russian Physician, approved at the 4th Conference of the Association of Physicians of Russia and the Declaration of Helsinki of the W orld Medical Association.

Objective: to analyze the incidence of temporary disability and take into account the labor factors of workers in the social service sector of a large city. Material and methods. The initial data were the number of employees of the Center for Social Services for the Population "Central" g. o. Samara, cases and days of temporary disability for 2018-2021. According to the compiled questionnaire, a survey was conducted of 150 social workers for a subjective assessment of health disorders, factors of conditions and nature of work. Results. In 2020, compared to 2019, the number of cases of temporary disability increased by 2.8 times, in 2021 — by 2.5 times; the number of missed days increased by almost 3 times, the largest number of cases of temporary disability in 2021 was registered in the group with 5-9 years of work experience (31 out of 128 cases; 24%). When interviewing social workers for the presence of their health disorders and affecting their ability to work, the most common symptoms were those of the respiratory system (56%), the musculoskeletal system and connective tissue (16%). It was revealed that the factors of the severity of the labor process correspond to the harmful class of working conditions of degree 3.1, the factors of intensity of the labor process — the harmful class of working conditions of degree 3.2. Conclusion. The identified features of morbidity with temporary disability must be taken into account when planning and conducting treatment and preventive work with social workers.

Introduction. Due to the increased psychoemotional load, the emergence of new sources of chemical, physical and microbiological effects on the health of medical workers, the study of the incidence of this category of workers is becoming increasingly important. The aim of study is to study social and hygienic issues related to the assessment of working conditions and health status of medical workers in the Samara Region. Materials and methods. Retrospective analysis of the results of medical and social monitoring of working conditions, health status and occupational morbidity of medical workers in the Samara Region. Results. Based on the analysis of data from the sanitary and epidemiological service and the Ministry of Health of the Samara Region on demographic and socio-economic situations, morbidity, and labor characteristics of medical workers in the Samara Region, a socio-hygienic assessment of working conditions of medical workers at the regional level was carried out. The high informative value of medical and demographic indicators in relation to the assessment of the impact of factors of the production environment on the health of health care workers and social services is shown. It is established that medical organizations generally do not meet the requirements of the current sanitary legislation in terms of ensuring safe working conditions for employees who come into contact with carcinogenic substances. Conclusions. The study of the demographic, socio-economic situation, and morbidity of medical workers with a hygienic assessment of health risk is a priority and serves as the basis for a comparative analysis of their morbidity and material for comprehensive hygiene studies.

The article presents the priority factors of the environment affecting the health of the working population. Measures to improve the quality of atmospheric air and drinking water in populated areas in the Samara region are indicated.
