Abstract

OBJECTIVE: The objective of this study was to elucidate the relationship between job stress and pulse wave velocity (PWV) as a cardiovascular risk factor.
METHOD
The study design was cross-sectional, and a total of 234 industrial workers were recruited. A structured-questionnaire was used to assess the general characteristics and job characteristics (work demand, decision latitude) using a modified Karasek model. Cuffs were applied to the extremities and a microphone for phonocardiography was placed at the second intercostal space at the margin of the sternum. The subjects rested in a supine position for 5 min, and PWV was measured using a VP-1000(Colin Waveform analyzer).
RESULTS
There were significant correlations between blood pressure, glucose, total cholesterol, coagulation factor and PWV. The group with low decision latitude and high decision latitude showed higher levels of PWV, but the differences were not significan. The PWV (left) was significantly higher in the high strain group than in the lower strain group. After adjustment for age and cardiovascular risk factors, job strain was still associated with PWV.
CONCLUSION
These result suggest that the high strain group among workers is related to an increased risk of PWV as a marker of atherosclerosis.
