Mortality from stomach cancer in United States cement plant and quarry workers, 1950-80

Abstract

In 1978 a study of the mortality of United States cement plant and quarry workers was initiated. The vital status of a cohort of 5292 men who had been employed for at least five years in a cement plant between 1950 and 1980 was traced to 1 January 1980. The mortality experience was evaluated for 4231 white men for whom complete work histories and demographic information were available. Deaths from stomach cancer were significantly increased during 1965-9 but not over the entire follow up period (1950-80). Additionally, stomach cancer mortality was not significantly associated with tenure under separate control for age at follow up, latency, nativity, or year of birth. Evidence from this and other epidemiological studies has not confirmed an association between the constituents of cement plant dust exposure and death from stomach cancer.
