Data from the 1980-1982 & 1985-1987 Minnesota Heart Surveys of currently employed Ss (N = 2,949 & 4,432, respectively) are used to explore the association between smoking & occupational status. In the first survey, the prevalence of current smokers ranged from 23% (professional) to 57% (service occupations) in men & from 15% (artists & writers) to 59% (repair & craft occupations) in women. Educational level, age, race, & sex were important predictors of smoking status in a logistic regression analysis that combined data from both surveys; occupational status was significantly associated with smoking after controlling for these covariables. Public health efforts should focus more on preventing smoking in lower educational groups & in occupational groups with the highest prevalence of smoking. 3 Tables, 17 References.
