[영문]Objective. We investigated the extent to which smoking status was associatedwith exposure to occupational (e.g., dust, chemicals, noise, and ergonomicstrain) and social (e.g., abuse, sexual harassment, and racial discrimination)workplace hazards in a sample of U.S. multiethnic working-class adults.Methods. United for Health is a cross-sectional study designed to investigatethe combined burden of occupational and social workplace hazards in relationto race/ethnicity, gender, and wage and to evaluate related health effects ina working-class population. Using validated measures, we collected data from1,282 multiethnic working-class participants using audio computer-assistedinterviews. We used multiple imputation methods to impute data for thosemissing data. Crude and adjusted logistic odds ratios (ORs) were modeled toestimate ORs and 95% confidence intervals (CIs).Results. The prevalence of smoking was highest among non-Hispanic whiteworkers (38.3%) and lowest for foreign-born workers (13.1%). We found anassociation between racial discrimination and smoking (OR51.12, 95% CI 1.01,1.25). The relationship between smoking and sexual harassment, although notsignificant, was different for black women compared with men (OR51.79, 95%CI 0.99, 3.22). We did not find any associations by workplace abuse or by anyof the occupational hazards.Conclusion. These results indicate that racial discrimination might be relatedto smoking in working-class populations and should be considered in tobaccocontrolefforts that target this high-risk population.
