Abstract
Introduction. The severity of the labor process is one of the leading harmful factors of working conditions in greenhouse vegetable growing. Nevertheless, its influence on the formation of health disorders of vegetable growers has not been sufficiently studied. Material and methods. Physiological, hygienic and epidemiological studies were carried out, which included an assessment of the severity of work in the annual cycle, also the functional state of the cardiorespiratory system and the neuromuscular system in the dynamics of the work shift, the general morbidity of vegetable growers according to registration forms No. 025/y. Results. During the labor activity, vegetable growers were established to be exposed to physical overloads caused by the severity of the labor process (classes 3.2, 3.3) in combination with a heating microclimate (classes 3.1-3.3). By the end of the work shift, there was an increase relative to the initial levels of heart rate (p<0.05), a decrease in systolic and diastolic blood pressure, a reduction of maximum muscle strength (by 3.76-5.28%), and endurance of the muscles of the hands (by 18.5-33.15%). This indicated a decrease in working capacity and an increase in fatigue. A reduction in the Skibinski index (by 21.7%) and an increase in the index of resistance to hypoxia (by 38.9%) indicated a decrease in the body’s reserves of oxygen. Increased working levels of the index of functional changes testify about the tension of adaptation mechanisms and insufficient restoration of the body’s resources by the beginning of the shift. A decrease in the body’s physical condition and adaptive capabilities with an increase in professional experience was revealed (p<0.05). There were established statistically significant direct correlations between the prevalence of diseases of the circulatory system (r=0.6), musculoskeletal system, and connective tissue (r=0.35) with work experience in the profession (p<0.05). Conclusion. The revealed violations of the functional state and health of female vegetable growers result from the influence of physical overload in a heating microclimate. The priority measures for the prevention of health disorders of vegetable growers are to reduce physical overload and thermal effects of the working environment.
