Two hundred forty-two Utah underground coal miners volunteered to participate in a respiratory disease study. They were an older group (mean, 56 years of age) and had spent a mean of 29 years in the coal-mining industry. The prevalence of chronic bronchitis was 57%, and that of coal worker's pneumoconiosis, 25%; only one worker had progressive massive fibrosis. Significant impairment of pulmonary function was found among those with a history of cigarette smoking. Chronic bronchitis or coal worker's penumoconiosis among nonsmokers did not impair pulmonary function. There was a significant association among the nonsmokers between increasing exposure to coal dust and coal worker's pneumoconiosis, but not for changes in pulmonary function. Coal mine dust had a significant influence in causing the symptom complex of chronic cough and sputum production, and coal worker's pneumoconiosis.
242名犹他州地下煤矿工人自愿参与一项呼吸系统疾病研究。他们年龄较大（平均56岁），平均从事煤矿行业29年。慢性支气管炎患病率为57%，煤工尘肺患病率为25%；只有一名工人患有进行性大块纤维化。有吸烟史者肺功能有明显损害。不吸烟者中的慢性支气管炎或煤工尘肺并未损害肺功能。在不吸烟者中，接触煤尘增加与煤工尘肺之间存在显著关联，但与肺功能变化无关。煤矿粉尘对引起慢性咳嗽和咳痰症状复合体以及煤工尘肺有显著影响。
