Race, occupation, and lung cancer: detecting disparities with death certificate data

Abstract

Objectives: To determine whether the analysis of death certificate data would reveal the same relationship among race, occupational exposure, and lung cancer mortality observed by a large cohort study.

Methods: An occupation-specific mortality odds ratio (MOR) for lung cancer (ICD-162) versus all other causes was calculated for 218,341 black men and white men who had been employed in the metal industries.

Results: Black men were at increased risk for lung cancer mortality when compared with white men among the 4668 oven workers (MOR = 1.38, 95% CI = 1.10 to 1.73), but not among the 33,605 white-collar workers (MOR = 0.95, 95% CI = 0.74 to 1.23).

Conclusions: Our findings corroborate a previously demonstrated association among exposure to carcinogenic coke oven emissions, race, and lung cancer mortality, and support the use of death certificate data to help identify occupations with racial disparities in lung cancer mortality.
