Evaluating the level of occupational stress and its influence factors among employees in a power supply enterprise with different models / 中国职业医学

ABSTRACT

OBJECTIVE: To investigate the occupational stress level and its influencing factors among employees in a power supply enterprise. METHODS: By cluster stratified random sampling method,251 workers in a power supply enterprise were selected as study subjects. The Simple Occupational Stress Questionnaire and the Chinese version of Effort-Reward Imbalance( ERI) Questionnaire were used to investigate and evaluate their job demand-control( JDC) and ERI occupational stress situation respectively. The related influencing factors were analyzed. RESULTS: Among the 251 workers,the positive rates of JDC high occupational stress and ERI high occupational stress were 74. 5%( 187 /251) and 22. 7%( 57 /251),respectively. The positive rate of JDC high occupational stress was higher than that of ERI occupational stress( P < 0. 01). The multivariate logistic analysis results indicated the risk of JDC high occupational stress in married workers was higher than that in single workers( P < 0. 05),workers with day-time working > 8 hours had higher risk of JDC high occupational stress than those workers with day-time working ≤8 hours( P < 0. 05). The male workers had higher risk of ERI high occupational stress than female workers( P < 0. 05). CONCLUSION: The main occupational stress model of workers in the power supply enterprise is the JDC model. The main influencing factors were marital status,day-time working hours and gender.
