[Association between job stress and blood lipids among university staff in Yunnan province].

OBJECTIVE

To observe the association between job stress (effort-reward imbalance model)and blood lipids among university staff in Yunnan province.

METHODS

A cross-sectional survey was conducted among 1244 university staff in Yunnan province. The job stress was measured by the validated Chinese self-reported Effort-Reward Imbalance Questionnaire (ERI). Blood lipids were measured in all participated staff members.

RESULTS

After adjustment for relevant confounding factors, it was found that the risk of increased serum triglyceride was 3.5 folds higher in male staffs with high extrinsic effort compared those with low extrinsic effort (OR = 3.45, 95%CI: 1.32 - 9.04) while the risk of increased serum low density lipoprotein-cholesterol was 2.9 folds higher in male staffs with high overcommitment compared those with low overcommitment (OR = 2.86, 95%CI: 1.03 - 7.96). The risk of elevated serum triglyceride increased in proportion to increasing job stress: 3.5 folds increase in male staffs with moderate job stress (OR = 3.43, 95%CI: 1.24 - 9.53) and 4 folds increase in male staffs with high job stress (OR = 4.16, 95%CI: 1.42 - 12.17) compared those with low job stress. However, there was no significant association between job stress and lipid profile in female staffs.

CONCLUSION

Our results show that job stress (effort-reward imbalance) is positively associated with abnormal blood lipids in male university staffs.
