A case-control study of lung cancer within the teamsters union.
Case studies in occupational epidemiology. Steenland K, ed. New York: Oxford University Press, 1993 Jan; :76-91
The lung cancer risk in men exposed to diesel exhaust in the trucking industry was investigated in a case control study. This study was described as part of a text book and took the reader through the same steps that the investigator took when conducting the actual study to allow the student to solve the same problems that the investigator solved in the course of the study. In the case control study the cases were all union pensioners who had died of lung cancer in 1982 or 1983, while controls were pensioners who died of other causes. Workers were divided into long haul drivers, short haul drivers, mechanics, and dock workers. An attempt was make to determine whether drivers had primarily driven diesel or gasoline powered trucks; most long haul trucks were diesel powered. The findings indicated that several occupations in the unions, presumably exposed to diesel fumes, had a slightly elevated risk of lung cancer compared to those in the union who presumably had no occupational exposure to diesel fumes. Perhaps the most important finding was that the risk of lung cancer increased with duration of employment of long distance truck drivers and also for diesel truck drivers.
