高校教职工职业紧张与血脂的关系

目的 探讨云南省高校教职工职业紧张(付出-回报失衡模式)与血脂的关系.方法 运用中文版的付出.回报失衡问卷对云南省某高校1244名在职教职工进行职业紧张测评,并同时对血清脂类进行了检测.结果 调整了相关因素后,在男性中,高外在付出组出现血清甘油三酯增高的危险性比低外在付出组增加了3.5倍(OR=3.45,95%CI:1.32～9.04),高内在投入组出现血清低密度脂蛋白胆固醇增高的可能性比低内在投入组增加了2.9倍(OR=2.86,95%CI:1.03～7.96).随着职业紧张(付出-回报比)的增大,出现高血清甘油三酯的危险性也逐渐增加,与处于低职业紧张状态的教职工相比,中等职业紧张状态的教职工发生高血清甘油三酯的危险性增高了3.5倍(OR=3.43,95%CI:1.24～9.53),而高职业紧张状态的教职工发生高血清甘油三酯的危险性则增高到4倍(OR=4.16,95%CI:1.42～12.17).在女性中,这种相关性不明显.结论 职业紧张(付出-回报失衡模式)与血脂异常相关.

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.
