新疆露天煤矿作业人群职业倦怠对职业性肌肉骨骼疾患影响的队列研究

职业倦怠和职业性肌肉骨骼疾患己经成为影响工作生活质量和工作效率的重要职业卫生问题。研究表明职业倦怠是煤矿工人中最严重的社会心理问题之一。煤矿工人也是职业倦怠和职业性肌肉骨骼疾患的高危人群。越来越多的证据显示社会心理因素是影响职业性肌肉骨骼疾患的重要因素之一。特殊自然环境会引起心理疾病，本项目组前期对新疆干旱沙漠作业人群的研究也证实了此观点。但已有的研究都是建立在横断面研究或病例对照研究的基础上，缺乏有力的病因学证据，缺乏暴露-反应关系。本研究通过队列研究探讨新疆露天煤矿作业人员职业性肌肉骨骼疾患的流行现状，利用BRIEF和PLIBEL工具对露天煤矿工人可能接触的不良工效学因素进行全面识别与评估，进一步证实社会心理因素职业倦怠与职业性肌肉骨骼疾患之间的病因关系，运用结构方程模型和人工神经网络模型建立职业倦怠影响职业性肌肉骨骼疾患发病的预测模型，为提高职业生命质量提供科学依据。

Job burnout and work-related musculoskeletal disorders have become an important occupational health problem which have negative effects on the life quality and work efficiency. According to some studies,job burnout has been the most serious psychological problems among the coal miners. The coal miners is considered as a high risk group for job burnout and work-related musculoskeletal disorders. Social psychological factors have become an important factor affecting work-related musculoskeletal disorders. The previous study showed that special natural environment lead to unhealthy psychological illness and reduce the quality of working life, we also found the same results in previous study on population working in arid desert.However ,there is few positive etiological basis in previous cross-sectional and case-control study. In this study, we will explore incidences and time trend of work-related musculoskeletal disorders of surface coal mine workers with cohort study, and investigate the high risk site of work-related musculoskeletal disorders and related ergonomic factors application of BRIEF and PLIBEL, and then confirm the etiology association between job burnout and work-related musculoskeletal disorders, and establish work-related musculoskeletal disorders predictive models by establishing structural equation model and artificial neural network model for improving the professional life quality and creating healthy work environment for coal miners.
