Diesel Exhaust in Miners Study (DEMS)
In March 2012, the National Cancer Institute (NCI) and the National Institute for Occupational Safety and Health (NIOSH) completed a retrospective cohort mortality and nested case-control study within the Diesel Exhaust in Miners Study (DEMS) cohort.
The researchers investigated risk of lung cancer in relation to quantitative measures of historical exposure to diesel exhaust, after taking into account smoking and other lung cancer risk factors among 12,315 workers at eight non-metal mining facilities. Elevated mortality from other causes among diesel exhaust-exposed miners was examined as well. An extensive effort to characterize current and historical exposures to diesel exhaust and to develop estimates of personal exposures was an intrinsic part of the study. Their results were published in the Journal of the National Cancer Institute. The methods for this effort were published in five papers in the Annals of Occupational Hygiene.
DEMS II, launched by the NCI in 2016, extends the follow-up of the original cohort by an additional 18 years and expands the nested case-control study of lung cancer by conducting interviews with next of kin for all newly identified lung cancer deaths and matched controls.
