Thyroid function was examined in 165 workers of electrolysis shops of aluminum production with more or less expressed signs of chronic fluoride intoxication (fluorosis) by radioimmunoassay of hormones and the test of 13II absorption by the thyroid. The detected thyroid abnormalities were characterized by a moderate reduction of iodine-absorbing function of the thyroid, low T3 with normal T4 level, and a slight increase of TTH concentration. These changes augmented with longer service and fluorosis progress. Hence, the syndrome of low T3 and reduced absorption of 1311 may be considered as diagnostic signs of fluorosis. In case of toxic involvement of the liver in fluorosis patients, low T3 syndrome is observed much more frequently: in 75.6% cases. Liver abnormalities evidently lead to disorders in the peripheral conversion of T4 in T3, occurring primarily in liver parenchyma. Indirect effect of fluorine on the enzymatic system of deiodination cannot be ruled out as well.

Introduction. Th e system of formation of a healthy lifestyle is recognized as the most important area of prevention. Studies of motivation for health and healthy lifestyles in workers engaged in harmful working conditions are few and indicate the negative impact of occupational disease on the psychosocial status of patients, a signifi cant impact of adherence to a healthy lifestyle on the prevalence and course of somatic diseases and the need to develop health-saving behavior.The aimof the studywas to study the prevalence of diff erent levels of motivation for maintaining health and a healthy lifestyle among workers in the metallurgical and coal industries.Materials and methods.72 workers of mines and sections of the South of Kuzbass with the established diagnosis of occupational disease were surveyed; 372 workers of the aluminum plant and 54 people who do not work in harmful working conditions (engineering and technical workers). The surveys were conducted by the method of «Motivation index for health and healthy lifestyle», alexithymia was evaluated by the method of «Toronto scale of alexithymia (TAS)» with the informed consent of the subjects.Results.Th e high level of motivation for health and a healthy lifestyle among employees of the aluminum industry corresponds to the population. Th e group of coal industry workers with occupational diseases surveyed is dominated by a low level of motivation to maintain health and a healthy lifestyle. In the group of workers who are not employed in harmful working conditions, a high degree of motivation for health and a healthy lifestyle is determined. Th e predominance of motivation on emotional and cognitive scales among workers not employed in harmful working conditions was revealed. In the group of coal industry workers with occupational diseases, the number of persons with a high level of motivation on an emotional scale has been reduced. Among persons with alexithymia signifi cantly reduced the level of motivation on an emotional scale. Among the workers of the coal industry with occupational diseases revealed signifi cantly higher prevalence of alexithymia.Conclusions. It is assumed that the link of reduced motivation for health in persons with occupational diseases with the presence of alexithymia.

Introduction. Adverse working conditions can contribute to the development of not only occupational pathology, but also diseases with complex multifactorial etiology, such as hypertension, coronary heart disease, disorders of the musculoskeletal system, chronic non-specifi c respiratory diseases, as well as the formation of combined pathology, which worsens the course of these diseases and leads to the development of complications.The aim of the study is to study the manifestations of somatic pathology in coal industry workers with vibration disease.Materials and methods. We examined 144 coal mine workers with vibration disease caused by local vibration, and 161 control group miners who have been working in contact with local vibration for a long time (15 years or more) and do not have professional pathology.It was found that employees of coal mines with vibration disease more often (70,8%) than workers of the control group (27,3%) (p<0,001), there is a pathology of internal organs: diseases of the cardiovascular system (mainly arterial hypertension), diseases of the digestive system (functional disorders of the biliary tract and non-alcoholic fatt y liver disease), kidney diseases (mainly chronic pyelonephritis), as well as a combination of these diseases. With a more severe course of vibration disease (II degree), pathology of internal organs is more common (81.2%) than in patients with vibration disease of I degree (46.5%) (p<0.001). Conclusions. In miners with vibration disease, more oft en than in the control group, there is a pathology of internal organs: the cardiovascular system, digestive organs, kidneys, as well as a combination of several somatic diseases. In individuals with grade II vibration disease, internal organ pathology is more common than in patients with grade I vibration disease. Th e results obtained should be considered when developing treatment and rehabilitation measures for medical examinations and conducting preventive medical examinations of coal industry workers. 

Introduction. Emotional burnout is a condition common among workers of “assisting” occupations. In workers of the main professions in the coal industry, the frequency of emotional burnout has not been studied enough, especially in terms of its relationship with mental health indices: the presence of sub-depression, negative affectivity, and social inhibition. The purpose of the survey was studying the prevalence of emotional burnout syndrome and its relationship with the development of sub-depression, negative affectivity and social inhibition in the coal industry workers with occupational diseases. Materials and methods. Two hundred forty seven miners with occupational diseases (dust lung pathology, diseases of the musculoskeletal system, vibration disease) were examined using questionnaires (DS14, by V.V. Boyko, and N.I. Vlakh). Results. 38.9% of the workers had emotional burnout syndrome. A reliable relationship between the emotional burnout syndrome and the development of sub-depression, negative affectivity and social inhibition was determined. Limitations. The survey is limited to a sample of 247 miners with occupational diseases examined using questionnaires (DS14, by V.V. Boyko, and N.I. Vlakh). Conclusion. Coal industry workers are subject to developing emotional burnout syndrome, the prevalence of which is 38.9%. The emotional burnout syndrome is interrelated with the development of sub-depression, negative affectivity and social inhibition, the incidence of which reaches a maximum in the exhaustion phase of burnout.
