ABSTRACT

Objective: To study the role of occupational stress in CHD (coronary heart disease) Methods: 39 male attendants on train with CHD were identified through Rose questionnaie and were confirmed after one year Two control groups were collected according to the rate of 1:2 and matched by sex, age, job, year of working separately in railway system (n=78) and hotel service (n=78) All subjects completed OSI (occupational stress indicator) Logistic regression model was used to analyze the data Results: Exceptfor non-occupational stress, the relative risk of train attendant working was estimated as OR=2 18 with 95% confidence interval of 1 15～4 15, and the risk for CHD as a train attendant had dose-effect relation to occupational stress Compared with controls of railway system without CHD, the relative risk of stress was still significant (OR=4 43, 95% CI: 1 60～12 25) But the relative risk (OR=9 75, 95%CI:3 18～29 92) was much higher when comparing with controls of hotel service Conclusion: Occupational stress is one of the important risk factors for CHD in male attendants on train
