Occupational Stress and Influencing Factors of Coke Oven Workers in a Coking Plant
摘要
Abstract
[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 and0.480).[Conclusion] Coke oven operation could result in elevated occupational stress in coke oven workers.Role overload,working at oven side or oven top,and poor working conditions could increase occupational stress;cultivating hobbies,having more entertainment and physical exercise,and adequate sleep could relieve it.关键词
