The prevalence of pneumoconiosis among working and nonworking miners in the Appalachian bituminous coal fields, and among working miners and nonminers and their respective wives in two West Virginia communities was surveyed from 1963 to 1965. Questionnaires were used to obtain medical, occupational, and smoking histories. Chest roentgenograms, ventilatory pulmonary function measurements and measurements of work capacity also were made. Coal workers' pneumoconiosis was a serious, widespread problem in Appalachia, with 10 percent of the working miners and 18 percent of the nonworking miners exhibiting roentgenographic evidence of the disease. These roentgenographic abnormalities that were definitely related to coal mining and were absent in other workers from the same area were related to duration of mine work and specific mining jobs. Although forced vital capacity was relatively normal in all categories, observed 1-second forced expiratory volume values were depressed in all categories, and the amount of depression was correlated with lung tissue involvement. Miners did not vary appreciably from other workers with regard to work capacity. The authors recommend that future studies of coal miners' pneumoconiosis include environmental data.
