列车乘务人员职业紧张与冠心病的关系

目的　研究职业紧张与冠心病之间的关系以及引起冠心病发病的主要职业紧张因素。方法　应用职业紧张测试表 ,对 5 83名男性列车乘务人员进行职业紧张与冠心病关系的人群调查。结果　在控制了非职业紧张因素条件下 ,职业紧张与冠心病有独立的相关关系 (RR =1 0 5 8,95 %CI :1 0 0 7～ 1 111) ,而且随着职业紧张程度的增加患冠心病的危险性也增高 ,引起冠心病发病的主要职业紧张因素是职务特征 (RR =1 12 5 ,95 %CI :1 0 48～ 1 196 )和经历与成就 (RR =1 172 ,95 %CI :1 0 99～ 1 2 5 6 )。结论　职业紧张是引起冠心病发病的一项不容忽视的重要危险因素

Studies on the relationship between occupational stress and coronary heart disease in train attendants

Objective To study the relationship between occupational stress and coronary heart disease (CHD) and the main occupational factors leading to stress.Methods A cross sectional study was conducted to study the relationship between occupational stress,evaluated by an occupational stress indication,and CHD in 583 male train attendants.Results Exposure to occupational stress was an independent risk factor for CHD with a relative risk(RR) of 1 058 and its 95% confidence interval(CI) of 1 007 to 1 111,adjusted for non occupational stress factors,in a dose response manner.Occupational stress factors causing CHD in train attendants mainly attributed to those intrinsic in their job,with a RR of 1 125 and its 95% CI of 1 048 to 1 196,and their career and achievements,with a RR of 1 172 and its 95% CI of 1 099 to 1 256.Conclusion Occupational stress was an important and un negligible risk facor for CHD.
