Work-related stress and early atherosclerosis

The purpose of this study was to examine the link between work-related stre ss and early atherosclerosis as measured by common carotid artery intima-me dia thickness and focal lesions in the common carotid artery and bifurcatio n. Four hundred sixty-seven members of an occupational cohort (total N = 57 3) were examined via questionnaires and B-mode ultrasound. We used multiple linear and logistic models to regress lesion risk and intima-media thickne ss on work-related stress scores from a questionnaire administered at an 18 month follow-up examination. In an age-adjusted model, the prevalence of c arotid lesions among men scoring in the highest stress quintile was 36% com pared with 21% among men in the lowest quintile. We also observed an increa se in intima-media thickness in the highest quintile relative to the lowest (difference = 0,048 +/- 0.025 mm) among men. Among women, stress was not r elated to the prevalence of lesions or intima-media thickness. These findin gs suggest that men with greater work-related stress are at increased risk for atherosclerotic disease. Women in this age group may be protected from such effects, or current work-place questionnaires may not accurately asses s stress in women.
