Abstract
BACKGROUND: Chronic inflammation may play an important role in linking job stress to atherosclerosis. We sought to investigate the relationship between job stress and high-sensitivity C-reactive protein (hs-CRP) among Chinese workers. METHODS: A total of 731 subjects (506 men and 225 women) were analyzed. Job stress was evaluated by effort-reward imbalance (ERI) model. RESULTS: Among men, after adjustment for confounders, effort, overcommitment, and ERI were significantly positively correlated with hs-CRP; and reward was significantly inversely related with hs-CRP; high level of effort, overcommitment, or ERI, respectively, significantly increased the odds of high hs-CRP with ORs of 2.0, 3.5, and 3.3 (all P<0.001), compared with the corresponding low level groups. Among women, high overcommitment or ERI also increased risk of high hs-CRP with ORs of 2.8, and 4.1 (P<0.05). CONCLUSIONS: High effort, overcommmitment, and ERI were positively associated with hs-CRP. Inflammation indicated by hs-CRP may be one of important mediators linking job stress and atherosclerosis.
