Occupational risk factors for the development of circulatory system diseases in bearing production workers

Abstract

Prevention of circulatory system diseases (CSDs), preservation of the health of the working population is a priority task of the Russian Federation healthcare, in the solution of which it is of interest to study the causal relationships of the influence of production factors on the development of CSDs in workers of various professional groups. The purpose of this study was to assess the prevalence and occupational causality of diseases of the circulatory system in the main professional groups of bearing production workers. Material and methods. The occupational risk of developing CSDs in workers of the main professional groups in the bearing production was assessed based on the hygienic classification of production factors and chronic non-infectious morbidity according to medical examinations using the methodology for assessing occupational health risk. Results and discussion. It has been established that bearing production workers in the course of labor activity are exposed to the complex effects of harmful (class 3.1–3.4) factors of the working environment of various nature, which determine the a priori occupational health risk in categories from low to very high. The level of CSD prevalence was 446.4‰, while arterial hypertension was the most frequently established nosologic form (80.66 %). A high degree of causal relationships of arterial hypertension with the work was established for adjusters and machine operators (RR = 2.44; etiologic fraction (EF) 58.98 %; CI = 1.335–4.450), turners (RR = 2.32; EF = 56.93 %; CI = 1.184–4.451), grinders (RR = 2.31; EF = 56.63 %; CI = 1.189–4.469), hot-spot workers (RR = 2.16; EF = 53.64 %; CI = 1.193–3.901), which indicates professional conditioning. Conclusions. The complex impact of production factors contributes to the development of CSDs among workers in the production of bearings, which is confirmed by a high degree of causal relationship between arterial hypertension and work.
