Abstract
Background
Stress-related hypercoagulability might link job stress with atherosclerosis.
Purpose
This paper aims to study whether overcommitment, effort–reward imbalance, and the overcommitment by effort–reward imbalance interaction relate to an exaggerated procoagulant stress response.
Methods
We assessed job stress in 52 healthy teachers (49 ± 8 years, 63% women) at study entry and, after a mean follow-up of 21 ± 4 months, when they underwent an acute psychosocial stressor and had coagulation measures determined in plasma. In order to increase the reliability of job stress measures, entry and follow-up scores of overcommitment and of effort–reward imbalance were added up to total scores.
Results
During recovery from stress, elevated overcommitment correlated with D-dimer increase and with smaller fibrinogen decrease. In contrast, overcommitment was not associated with coagulation changes from pre-stress to immediately post-stress. Effort–reward imbalance and the interaction between overcommitment and effort–reward imbalance did not correlate with stress-induced changes in coagulation measures.
Conclusions
Overcommitment predicted acute stress-induced hypercoagulability, particularly during the recovery period.
