摘要:Objectives. This study examined occupational risks for non-Hodgkin’s lymphoma, Hodgkin’s disease, and soft-tissue sarcoma among African American and White men. Methods. Race-specific multivariate logistic regression analyses were conducted using data from a large US population-based case–control study. Results. Significant occupational risks were limited to African Americans; chromium was associated with non-Hodgkin’s lymphoma (odds ratio [OR] = 3.9, 95% confidence interval [CI] = 1.2, 12.9) and wood dust was associated with Hodgkin’s disease (OR = 4.6, 95% CI = 1.6, 13.3) and soft-tissue sarcoma (OR = 3.7, 95% CI = 1.6, 8.6). Conclusions. Race-specific occupational risk factors for cancer were evident only among African American men. This may reflect racial disparities in levels of exposure to occupational carcinogens. African American men in the United States have a much higher cancer incidence than White men, but rates among African American and White women are similar. 1 This disparity may be attributable, in part, to disproportionate exposure of African American men to hazardous occupational conditions. 2– 4 However, data are sparse on race-specific occupational risk factors for cancer. 4, 5 Furthermore, published reports have generally been based on data from death certificates and other secondary sources, which have questionable validity because of racial disparities in accuracy. 6, 7 In this exploratory study, we examined race-specific occupational risk factors for non-Hodgkin’s lymphoma, Hodgkin’s disease, and soft-tissue sarcoma using data provided by African American and White men aged 32 to 60 years who participated in the Selected Cancers Study. 8– 11
