Chronic Respiratory Disease in Mining Communities in Marion County, West Virginia

AUTOR(ES)
RESUMO

A study of respiratory disease has been carried out in five mining communities in Marion County, West Virginia, United States of America. Each of the five communities was defined by a private census. A questionnaire on respiratory symptoms, chest and other illnesses, smoking habits, and occupation was completed on all adults aged 20 years and over. All men aged 20-69 who lived in three of the towns were asked to attend at a centre for examination and 83% responded. The examination included the completion of a further questionnaire on respiratory symptoms, occupation, and smoking habits; examination of the chest; simple tests of ventilatory lung function; and a 14 × 17 in. postero-anterior radiograph of the chest.
