Associations between past myocardial infarction (M.I.) prevalence and job characteristics were tested among employed white males in two large scale clinical surveys of cardiovascular illness: US Health and Nutritional Examination Survey (HANES) 1971 - 1974 (N= 2153). US Census occupation codes (441 categories), industry, and self-employment status are available on the surveys. A new job characteristics inference method is used which imputes scores to census occupation codes based on national surveys, (US Quality of Working Life Surveys: 1969, 1972, and 1977). Job characteristic hypotheses are tested using these occupational scores as simple means and as means adjusted for demographic factors such as age, race, education, self-employment, marital status, urbanicity, and religion. Controlling for age, (race, sex), and using mean job scores, we find that jobs which are simultaneously low in decision latitude and high in psychological work load, (a multiplicative interaction iso1ating 25% of the population), have significantly higher prevalence of myocardial infarction (p < / = 0.001 HANES), confirming findings in Swedish incidence data using a similar job characteristic model and cardiovascular mortality. In a further multiple logistic regression analysis using the scores adjusted for demographic factors and controlling for age, education, systolic blood pressure, smoking, (HANES), we find low decision latitude to be significantly associated with myocardial infarction prevalence in the HANES, (p < / = 0.003). Psychological job demands are positively associated with M.I. in the HANES, (p < / = 0.02). Job physical exertion is negatively associated with M.I. prevalence in the HANES, (p < / = 0.002).
