[目的]调查焦炉工职业紧张状况,分析其主要影响因素,为合理防控职业危害提供依据。[方法]采用整群抽样方法,选取山西某焦化厂焦炉工335人、非焦炉工246人为研究对象,调查表收集研究对象的一般情况,采用职业紧张量表（OSI-R）进行职业任务、个体紧张反应及个体应变反应三方面调查。采用高效液相色谱法测定工作场所空气中苯并[a]芘浓度,比较各作业区的暴露水平。[结果]工作场所空气中苯并[a]芘浓度变化趋势是非焦炉区〈炉底〈炉侧〈炉顶（P=0.001）。焦炉工职业任务平均得分[（182.87±27.28）分]和个体紧张反应得分[（102.97±18.74）分],均高于非焦炉工（均P〈0.001）;个体应变能力问卷得分[（124.47±22.27）分]低于非焦炉工得分[（126.54±23.07）分]（P〈0.05）。根据OSI-R量表的3个问卷得分将职业紧张分级,焦炉工职业任务和个体紧张反应分级,处于高度紧张工人的比例为10.8%和11.6%,中度紧张的比例为31.0%和25.1%,高于非焦炉工（2.8%和1.2%,15.4%和22.8%,均P〈0.05）。logistic回归分析显示,任务过重、炉侧作业和工作环境差是引起个体紧张反应增强的危险因素,OR值分别为3.187,2.307和1.813;增加兴趣爱好、休闲娱乐、体育锻炼及充足的睡眠是职业紧张的保护性因素,OR值分别为0.240,0.451,0.566及0.480。[结论]焦炉作业可导致焦炉工职业紧张度升高,任务过重、炉顶炉侧作业和工作环境差可升高焦炉工职业紧张度;增加兴趣爱好、休闲娱乐机会和体育锻炼参与度以及充足的睡眠可缓解焦炉工职业紧张度。

英文摘要：

[Objective] To assess occupational stress level of coke oven workers, analyze main influencing factors, and provide a basis for rational control of occupational injuries. [Methods] Coke oven workers（n=335） and control workers（n=246） from a coking plant in Shanxi Province were selected by cluster sampling method and interviewed on basic information using a general questionnaire and on occupational role, personal strain, and personal resource using the Occupational Stress Inventory Revised Edition（OSI-R）. Benzo（a）pyrene concentrations of workplace air were evaluated by high performance liquid chromatography, and the benzo（a）pyrene exposure levels of each work area were compared. [Results] The benzo（a）pyrene concentrations of workplace air showed a trend of non-hearth furnace oven bottom oven side oven top（P=0.001）. The coke oven workers＇ scores of occupational role questionnaire（ORQ）（182.87±27.28） and personal strain questionnaire（PSQ）（102.97±18.74） were significantly higher than those of the control workers（both Ps 〈0.001）. Their score of personal resource questionnaire（124.47±22.27） was significantly lower（126.54±23.07）（P〈0.05）. Sub-groups were divided according to the scores of each questionnaire, the high score groups accounted for 10.8%（ORQ） and 11.6%（PSQ） of total workers, and the middle score groups accounted for 31.0%（ORQ） and 25.1%（PSQ） respectively, significantly higher than those of the control group（2.8% and 1.2%, 15.4% and 22.8%, all Ps〈 0.05）. By the logistic regression analysis, role overload, working at oven side, and poor working conditions were the risk factors for enhancing individual strain response（OR were 3.187, 2.307, and 1.813）; whereas cultivating hobbies, having more entertainment and physical exercise, and adequate sleep were protective factors（OR were 0.240, 0.451, 0.566 and 0.480）. [Conclusion] Coke oven operation could result in elevated occupational stress in coke oven workers. Role ove
