Abstract:
Objective To study the relationship between the rate of dyslipidemia and occupational stress factors.
Methods Cluster sample survey was conducted in 521 male railway policemen, train crew and white-collar workers with length of service more than 3-years. They were investigated by our self-made questionnaire including general situation, behavior and life situation. They were also surveyed by using state-trait anxiety inventory (STAI), occupational stress inventory revised edition (OSI-R)and Type A behavior scale. The risk factors of state-trait anxiety were analyzed by multivariate conditional logistic regression.
Results (1) Policemen, train crew and white-collar had different levels of occupational stress and different dyslipidemia rate. After adjustment for body mass index(BMI), the rate of dyslipidemia was 85.0%, 43.6% and 37.9% respepctively, dose-response relationship could be observed between occupational stress and the rate of dyslipidemia. (2) Mediating factors of occupational stress (type A behavior)was a risk factor for dyslipidemia (OR=1.68). (3)Job was the risk factor of triglyceride (TG), high-density lipoprotein (HDL)and dyslipidemia; type A behavior was the risk factor of total cholestero(l TG), TC and dyslipidemia.
Conclusion (1)Different type of job had different levels of occupational stress and different rate of dyslipidemia. (2)The rate of dyslipidemia associated with mediating factors of occupational stress. (3)The risk factors of dyslipidemia were the job, BMI and type A behavior, different indices (TC, TG, HDL, low-density lipoprotein)of blood lipids had different risk factors.
