    Abstract:
    OBJECTIVE: Gun factory workers are exposed to many solvents (toluene, acetone, butanol, xylene, benzene, trichloroethylene). We investigated whether chronic exposure to solvents had adverse effect on respiratory system. MATERIAL AND METHODS: The workers were questionnaired by modified Medical Research Council's respiratory questionnaire before morning start shift. Then physical examination and measurement of pulmonary functions by portable dry rolling spirometer were performed. The study group consisted of 1091 gun factory workers. The workers were grouped according to their smoking habits (smokers, [exposed n: 353 vs. unexposed n: 339] and non-smokers [exposed n: 58 vs. unexposed n: 341]). Asthma-related symptoms were defined as either definite asthma, probable asthma, and possible asthma. RESULTS: In non-smokers, the report of asthma-related symptoms was more prevalent in exposed workers than unexposed (39.7% vs. 21.7% OR 2.4[1.3-4.3], respectively P = 0.003). In smokers, the report of asthma-related symptoms was more common in exposed group than unexposed (50.7% vs. 42.5% OR 1.4[1.0-1.9], respectively P = 0.03). Logistic regression analysis showed that smoking (OR 2.8[2.0-3.8] P = 0.00001) and exposure to solvents (OR 1.4[1.1-1.9] P = 0.01) were independent risk factors for asthma-related symptoms, after adjusting for age. Logistic regression analysis identified that smoking (OR 3.3[2.3-4.6] P = 0.00001) was independent risk factors for chronic bronchitis. Multiple linear regression analysis of lung-function parameters (% forced expiratory volume (FEV1), FEV1/forced vital capacity, FEF(25-75)) indicated significant effects of smoking. CONCLUSION: Present study indicated significant effects of smoking and exposure to solvents, with the smoking effect being the most important on asthma-related symptoms of gun factory workers.
