Introduction. Unfavourable factors of the working environment affect bone tissue, increasing the risk of developing osteoporosis in workers of harmful industries, which is an urgent social and hygienic problem due to the high prevalence and severity of medical and social consequences. The aim of the study was to investigate the impact of industrial vibration and physical overload on the markers of bone metabolism in industrial workers. Materials and methods. One hundred fifty-two employees of mining and mechanical engineering enterprises in contact with industrial vibration and physical overload were examined. The assessment of bone tissue metabolism in the workers was carried out by the method of solid-phase enzyme immunoassay to determine biochemical markers of bone metabolism: bone alkaline phosphatase, osteocalcin, C-terminal serum telopeptide, cathepsin K, as well as indicators of calcium-phosphorus metabolism. X-ray densitometry was used to assess bone mineral density. Results. There was a significant decrease in the markers of osteogenesis: the concentration of CSF (14.26 ± 4.13 and 18.69±5.28, respectively, p< 0.05) and osteocalcin (12.23±4.15 and 17.84±5.17, respectively, p < 0.05) and an increase in the markers of bone resorption: the level of beta-CrossLaps (0.629±0.162 and 0.361±0.095, respectively, p = 0.002) and the level of cathepsin K (12.49±5.28 and 0.59±0.02, respectively, p < 0.001) in workers of industrial enterprises exposed to physical factors of production. The correlation between the markers of bone metabolism and the experience of exposure to adverse working conditions was established. Conclusion. Combined exposure to physical labour factors is a predictor of calcium-phosphorus metabolism and bone metabolism disorders, increasing the risk of metabolic osteopathy in industrial workers.

Introduction. In response to the action of various occupational factors, central regulatory mechanisms, including the hypothalamus, are involved. Clarification of the influence of the hypothalamus on the indicators of peripheral blood circulation, peripheral innervation and bone metabolism under the influence of vibration and physical overloads is relevant for the diagnosis and treatment of occupational diseases of a neurological profile. The aim of the study. To establish the relationship between hypothalamic disorders and functional indicators of occupational diseases of the peripheral nervous system under the influence of vibration and physical overloads. Material and methods. One hundred fifteen tunnellers and machinists of the drilling rig of JSC “KMAruda Combine”, 26 tunnellers of the drainage mine of JSC “Stoilensky Mining and Processing Plant”, 65 workers of auxiliary occupations were examined. Depending on the influencing factor, they were divided into four groups with occupational neurological pathology, the fifth group was control Examined cases were divided into subgroups: A - without hypothalamic disorders and B - with hypothalamic syndrome. The criteria for the diagnosis of hypothalamic syndrome are clinical. All the examined patients underwent rheovasography, stimulation electroneuromyography of the extremities, ultrasound densitometry. Results. It was found that in patients with vibration disease from the effects of local or general vibration, especially when combined with lumbosacral radiculopathy during rheovasography, there are decrements in pulse blood filling, changes in vascular tone in vessels of various calibers and venous dysfunction, which are aggravated against the background of hypothalamic disorders. Hypothalamic disorders contribute to the aggravation of peripheral nerve indices: a decrease in the amplitude of the M-response, the rate of propagation of excitation along sensory axons and an increase in the value of residual latency. Functional assessment of bone tissue revealed the greatest prevalence of osteopenia syndrome in patients with vibration disease and its combined forms with lumbosacral radiculopathy in subgroups with hypothalamic-pituitary dysfunction (up to 33.6%). The frequency of detected functional disorders was established to increase with the progression of occupational diseases. Limitations. The study was conducted in workers with neurological occupational diseases exposed to vibration and physical overloads. Conclusions. Neurohumoral disorders, manifested by hypothalamic syndrome caused by exposure to general and local vibration in combination with physical overloads, contribute to the development or aggravation of functional changes in the body of workers, aggravating the course of occupational diseases of the peripheral nervous system, which can be used to develop diagnostic and treatment methods, and study the pathogenesis of diseases.

Introduction. The adverse effects of both production factors and the labour process affect the bone mineral density, increasing the risk of developing osteopenic syndrome in workers of harmful industries, which is an urgent social and hygienic problem due to the high prevalence and severity of medical and social consequences. Objective. The study of the state of bone tissue in miners whose occupational activities are associated with the impact of vibration (general and local). Materials and methods. For the period 2015-2022, there were examined three hundred twenty mining workers, whose activities were associated with exposure to general and local vibration (group 1). The average age of the workers was 46.64±2.33 years. The comparison group (Group 2) consisted of 290 men without identified pathology of the musculoskeletal system, not employed in production associated with exposure to general and local vibration and who gave voluntary consent to the study. The average age of the examined cases is 45.57±2.28 years. Markers of bone formation and bone resorption in body fluids were analyzed. The statistical data were expressed as an average value ± standard deviation. The differences were checked using the T-test. The values of p <0.05 were considered statistically significant. Results. The T-score in patients of group 1 ranged from -1 SD to -2.5 SD (-1.41±0.07*), which corresponded to osteopenia. Elevated levels of CRP (4.24±0.20 mmol/L), ESR (8.91±0.45 mm/h) and leukocytes (12.91±0.70×109 g/L) were revealed among patients of group 1. Changes in the state of calcium-phosphorus metabolism among patients of the 1st group were noted. The formation of osteopenic syndrome was accompanied by an imbalance between the processes of resorption and bone formation in group 1 patients (p<0.05). Limitations. The process under study was osteopenic syndrome, 310 workers - a quantitative parameter, mining production - a qualitative indicator. Conclusion. According to the results of laboratory and instrumental methods of research, osteopenic syndrome was revealed in workers in vibrio-hazardous occupations. Its early diagnosis, determination of a complex of specific treatment and rehabilitation techniques will prevent the progression of the pathological process and maintain professional orientation.

Introduction. The health of employees of harmful industries indicates its disadvantage and dependence on behavioural and occupation risk factors, promoting the formation of diseases associated with their impact. In this regard, it is essential to improve hygienic and medical-preventive measures to strengthen and restore the health of the able-bodied population, based on the use of health-saving principles aimed at developing skills for a healthy lifestyle and monitoring predictors of functional disorders of the body and the health of workers. The purpose of the study. Implementation and evaluation of the effectiveness of preventive measures using health-saving methods to optimise the production environment and extend the longevity of workers working in harmful working conditions. Material and methods. Two hundred eighty-two employees of the “Starooskolsky plant of automotive electrical equipment named after A.M. Mamonov” exposed to harmful factors of the working environment were examined. The health status of employees was assessed according to the data of periodic and preventive medical examinations, medical documentation, with an assessment of the prevalence of priority classes of diseases. Behavioural risk factors (smoking, physical activity, the nature of nutrition) and associated functional indices of health disorders were studied: body mass index, biochemical indices. A health-saving program was proposed and tested, including an organisational, training and monitoring unit. Results. The health status assessment of the workers of the studied enterprise showed the structure of morbidity to be formed by cardiovascular pathology, diseases of the spine and joints, respiratory organs, the psycho-emotional sphere, endocrinopathy, reaching almost 70%. More than half of the employees are overweight against the background of an unbalanced and irrational diet, a low level of physical activity, and lipid metabolism disorders. The introduction and testing of a preventive program developed on principles of health saving contributed to improving the health of employees and reducing morbidity. Conclusion. The recommended set of health-saving measures contributed to optimising working environment conditions, correcting the state of health of employees, and prolongation of labour longevity.
