职业紧张对石油工人血脂代谢的影响

目的 探讨职业紧张对石油工人血脂代谢的影响，为其健康管理提供理论依据。方法 选取2017年4月-2018年4月参加职业健康体检的某石油企业在岗工人作为研究对象，共2241名工人纳入本次研究。采用中文版《工作内容问卷》评估职业紧张水平；采集工人空腹状态肘静脉血，检测血清总胆固醇（TC）、甘油三酯(TG)、高密度脂蛋白(HDL-C)、低密度脂蛋白(LDL-C)水平。结果 石油工人血脂异常率为52.03%，其中血清TC异常率27.49%，血清TG异常率29.41%，血清HDL-C异常率12.23%，血清LDL-C异常率22.80%。采用多因素logistic回归分析显示:调整年龄、性别、BMI等混杂因素后，与低紧张型工作状态下工人相比，高紧张型工作状态的工人发生血清TC异常、LDL-C异常的风险更高（P<0.05，OR值分别为1.35、1.42），高社会支持状态下发生血清LDL-C异常风险降低（P<0.05,OR=0.77）。结论 职业紧张是石油工人血清TC、LDL-C异常的危险因素，社会支持是石油工人血清LDL-C异常的保护因素。

Effects of occupational stress on blood lipid metabolism in oil workers

To explore the effects of occupational stress on blood lipid metabolism of oil workers，and to provide theoretical basis for their health management. Methods A total of 2，241 employees of an oil company who participated in the occupational health examination from April 2017 to April 2018 were selected as the study objects. The Chinese version of the job content questionnaire was used to assess the level of occupational stress. Fasting elbow venous blood was collected and serum levels of total cholesterol ( TC) ，triglyceride ( TG) ，high － density lipoprotein ( HDL － C) and low － density lipoprotein( LDL － C) were detected. Ｒesults The rate of dyslipidemia in oil workers was 52. 03% ，including 27. 49% of serum TC，29. 41% of serum TG，12. 23% of serum HDL － C and 22. 80% of serum LDL － C. Multivariable Logistic regression analysis showed that after adjusting for age，sex，BMI，smoking，drinking and other confounding factors，compared with workers of low tension type at work，workers of high tension type at work had higher risk of abnormal serum TC，LDL － C ( P ＜ 0. 05，OＲ values were 1. 35，1. 42) ，and the workers with high social support had lower risk of abnormal serum LDL － C ( P ＜ 0. 05，OＲ= 0. 77) . Conclusion Occupational stress is a risk factor for abnormal serum total cholesterol and LDL － C，while social support is a protective factor for abnormal serum LDL －
