Proportionate Mortality Study of the United Association of journeymen and Apprentices of the Plumbing and Pipe Fitting Industry

Background This study examined causes of deaths among unionized plumbers, pipefitters and allied trades. Methods Deaths of union members from. the years 1971, 1979, 1987, and 1995 were selected as a representative sample from a computer file provided by the union. These years provided 15,411 deaths for proportionate mortality ratio (PAIR) analysis. Results PMRs for lung cancer and asbestosis were significantly elevated compared to U.S. white males. PMRs for chronic disease of the endocardium and cardiomyopathy were also elevated. Elevations were not observed in other a priori causes: laryngeal cancer lymphatic cancer and neurological disorders. PMRs.for transportation accidents for pipe/steam-fitters were elevated in 1971 and 1979, but not in 1987 or 1995. Conclusion Despite the limitations of a PMR analysis, study results indicate mortality related to asbestos exposure is, and will continue to be, an area of concern for members of the union. Am. J.
