Asbestos Disease in Commercial Roofers: Radiologic Signs.
NIOSH 1990 Nov:1414-1417
In 1987 the Roofers International Union, Local 3, sponsored a medical group survey program for members. This Local represented approximately 30% of the commercial roofers in the Boston metropolitan area. The program provided a physical examination, chest X-rays, spirometry and detailed occupational and medical history for each worker with 10 years or more membership in the union which totalled 271 individuals. Sixty nine participated in the study. The mean age of the examined population was 52 years and the mean number of years as a roofer was 29. The vast majority had more than 10 years in the trade, with 74% having more than 20 years at the time of the study. Radiologic evidence of pleural disease was noted in 67% of the population, 46 individuals. The mean age of this group was 54 years with union membership of 29 years. A significant relationship was noted between years as a roofer and prevalence of pleural disease. Eighty percent of roofers with 20 or more years in the trade had evidence of pleural abnormalities. Parenchymal abnormalities were not common with only two individuals having radiologic evidence of fibrosis. Both individuals with parenchymal fibrosis had more than 20 years membership in the union. No relationship was noted between smoking status and the presence of pleural abnormalities.
