title: [Evaluation of the incidence of clinical symptoms and risk factors for COPD based on the monitoring of refinery workers in Piock (1993-1996)].
abstract: Work place environment plays an important role in development diseases because of the time spend in and different toxic factors placed in it. The aim of study was to assess the ventilatory efficiency in individuals employed in Generating Plant (GP) in relation to the pollution of the work place and the tobacco smoking habit during 3 years. The study covered a group of 144 male individuals employed at GP. (age 39.3 +/- 8.7 yrs, period of employment 20.3 +/- 8.6 yrs, smokers 53.5%. Lung function tests consisted of VC, FVC, FEV1, FEV1%VC, PEF, FEF50 counted from flow-volume curve and TGV, Rt measured using pletysmographic method. All tests were performed using pletysmograph (Masterlab) "Jaeger" placed on the ambulance near to the work place. The measurements were taken in May 1993 and 1996. Results were compared to with normal values (acc. ECSC). The anamnesis was obtained from all workers in the form of questionnaire projected for this study. All measurements were done during work time (9.00 a.m. to 2.00 p.m.). Mean values of the ventilation indices remained within the normal range but comparing results in smokers and non-smokers group significant differences in FEV1 and TGV were found. The symptoms of chronic bronchitis were present in 20.8% of persons. Spirometric criteria for the COPD diagnosis were found in 16 persons (11%). Only 5 persons (31%) were symptomatic. The mean decrease of FEV1 was 16.2 ml/yr, in the COPD group it was 82.5 ml/yr. The greater annual loss of FEV1 was found in the smokers and symptoms groups.
