Abstract
An epidemiological study into the prevalence of chronic bronchitis was carried out in a group of 2401 male industrial workers. The relationship between subjective symptoms recorded by a standard questionnaire and certain objective findings relevant to chronic bronchitis was analyzed. The finding of chronic bronchitis, which was defined on the basis of subjective symptoms, was only partly associated with concurrent objective signs of respiratory infection and ventilatory obstruction. A fairly good association between the degree of dyspnea and reduced FEV1,0/FVC (%) values was observed. However, in the case of advanced dyspnea the association with the objective finding of obstruction was less than expected.
