OBJECTIVE: The studies focusing on effort-reward imbalance and diabetes mellitus (DM)/glycosylated hemoglobin (HbA1c) are rare. We sought to examine the association between job stress evaluated by effort-reward imbalance (ERI) model and HbA1c in a Chinese population. METHODS: We analyzed 680 subjects (465 men and 215 women) without DM or impaired glucose tolerance from the stress and health in Shenzhen workers (SHISO) study. Job stress was evaluated by effort-reward imbalance (ERI) model. HbA1c was measured by an automatic analyzer by means of high-performance liquid chromatography. The association between job stress and HbA1c was explored by variance analysis, partial correlations and multiple linear regression analysis. RESULTS: For women, effort, and ERI were positively associated with HbA1c (r = 0.22, p = 0,003; r = 0.21, p = 0.006, respectively), in contrast, reward was negatively associated with HbA1c (r = -0.17, p = 0.021), after controlling age, BMI and physical exercise in the partial correlation analysis; the similar results were confirmed in the multiple linear regression. No significant correlations between job stress and HbA1c were found for men. CONCLUSION: Effort and ERI are positively associated with HbA1c, and reward is inversely related to HbA1c among Chinese women. The association is not accounted for by age, BMI, and physical exercise. More efforts should be made to improve the job stress status of Chinese working women for the purpose of DM prevention.
