Shanxi Coal Mine Workers, Occupational Stress In The Current Situation And Its Influencing Factors Research

Objective To investigate the status of the occupational stress and its factors of coal workers in Shanxi, to develop the targeted interventions to ease occupational stress of coal miners, and to provide a scientific basis to improve the quality of work.Methods Stratified cluster sampling was used with working teams as sampling units. The coal miners from Shuang Liu, Zhai Yangdi, Jin Jiazhuang, Xing Wu, Huo Xi, Yu Xing, Xin Yuan and Zhong Xing in Shan Xi were seleted. Occupational Stress Questionnaire (OSI-R) and questionnaire of sociological factors were assessed.Results We got 2651 validated from 3000 questionnaires with answering rate 88%. The mean scores in three domains of OSI-R of coal miners were 49.89±11.31 (Occupational Role), 38.14±12.66 (Personal Strain),58.01±17.58 (Personal Resources) and 48.85±10.04 (total), respectively. There were no statistically significant difference between these scores of coal workers and normal peoples. Through the single-factor analysis, work units, illness, the system of working hour, work fatigue, work intensity among more than 30 factors were significantly related to occupational stress. Being satisfied with the unit, the social status of work, weekly working days, years of touching dust, years of underground work, work-risk level, work intensity, work fatigue, physical examination, the working units were related to all domains of occupational stress. SAS multiple regression analysis showed that the significant factors of three domains of occupational stress were different. Hobbies, asthma, administration title, working hours per day, smoking every day, weekly working days, drinking had greater impact on occupational stress to the coal workers from the overall evaluation.Conclusion The status of the occupational stress of coal workers in Shanxi was not serious and it was related with hobbies, asthma, administration title, working hours per day, smoking every day, weekly working days, and drinking. The following measures may effectively ease the stress of the workers:take the necessary protective measures to reduce the inhalation of coal dust which could induce the asthma and bronchitis; reduce the incidence of respiratory diseases of workers; increase appropriatly the support in terms of exercise and recreational activities; enhance the workers' participating in enterprise management and decision-making, arrange for reasonably working hours and workload; and keep the working environment harmony.
