Title: Occupational exposure and status of respiratory health in workers of sulphur mines and the sulphur industry


Objective The purpose of the study was to establish the relationship of occupational risk and respiratory health in young people working in industry. Methods The prospective study was administered to 909 men, sulphur mine and sulphur industry workers, aged 25 to 28 years. Data on health status: chronic cough, phlegm, wheezing independent of colds, attacks of dyspnea, as well as demographic factors, smoking habits, occupational exposure, physical activity and living conditions were collected by interview. Spirometric values were measured to assess lung function. The population was examined each year over a 5-year period and 79,3% of the participants took part in at least two examinations. Risk to respiratory health through occupational exposure was assessed using multivariate models adjusted to smoking history, BMI, physical activity and living conditions. Results and Conclusions The incidence of new cases of chronic cough and chronic phlegm depends on exposure to irritant gases or chemical compounds. The relative risks were respectively 1.63 (95%CI: 1.04; 2.56) and 2.06 (95%CI: 1.31; 3.26). Exposure to dust was not associated with increased risk of new respiratory symptoms. In workers exposed to high or variable temperature, average annual decrease of FEV1 was 40 ml/year greater (95%CI: - 71.3; - 8.9) than in those not so exposed. Average annual decrease of FEV1 was higher in new cases of chronic phlegm ( = -33.8.; 95%CI: -64.3; -3.2) and slower in remission cases (= 40.2; 95%CI: 5.2; 75.2). Tobacco smoking significantly increased the incidence of all studied symptoms but did not affect lung function significantly.
