• Description:
  Bituminous coal miners (8,555 men) are subjected to a limited medical examination consisting of spirometry, chest X-rays, and a respiratory questionnaire to determine the relationship of chronic bronchitis and airway obstruction to dust exposure and cigarette smoking. The prevalence of bronchitis is found to have increased with age and become higher in smokers than in nonsmokers or exsmokers. Surface workers have less bronchitis than face workers, reflecting their lower dust exposure, but the difference is statistically significant only for nonsmokers and exsmokers. The ratio of one-second forced expiratory volume to forced vital capacity is less than predicted in 37.6% of nonsmokers, 50.5% of exsmokers, and 58.8% of smokers. Airway obstruction occurs in surface workers less frequently than in face workers. Analysis of the difference between smoking face workers and nonsmoking surface workers reveals that the effect of smoking is 5 times that of coal dust. [Description provided by NIOSH]
