[The specific features of the development of chronic non-infectious diseases in mechanics at the petrochemical plants].

The present-day petrochemical plant workers, such as 533 process installation repairmen and 332 control instrumentation and automation installation repairmen, were the subjects of the study. The working conditions and the specific features of the formation of non-communicable diseases were examined in the workers of the above occupations. The specific features of the development of musculoskeletal and circulatory diseases and hearing impairments were revealed in the workers depending on the conditions and nature of their work. The data were statistically processed using the correlation coefficient r and the chi2 test at p < 0.05. The parameters were standardized for the examinees' age. During the study, the authors accepted the hypothesis that working conditions affected the prevalence of individual types of chronic non-communicable diseases in process installation repairmen.
