Juon HS, Hong A, Pimpinelli M, et al. - This study was sought to explore occupational exposure to asbestos, silica, and other workplace chemicals, fumes, or dust as reported in the National Lung Screening Trial (NLST). Researchers conducted descriptive analyses and multivariate logistic regression models. In the analysis, 3.9% were diagnosed with lung cancer among the NLST study cohort. It was shown that African-Americans had a higher rate of lung cancer diagnosis than White individuals (4.3% vs. 3.9%). At least one occupational exposure was reported by about 28% of respondents, including 6.5% exposed to silica and 4.7% to asbestos. Occupational exposure was reported more frequently by African-Americans than White participants, including exposures to asbestos and silica. The interactions of all measures of occupational exposures and smoking status were significant in a multivariate model. African-Americans had higher odds of lung cancer diagnosis than White individuals. More effective public health prevention programs are needed, particularly for minorities who may have disproportionately greater occupational exposures
