目的调查机械加工业工人职业性肌肉骨骼疾患的患病情况。方法采用横断面调查方法,对北京市丰台区4个机械加工行业工厂990名工人进行肌肉骨骼疾患的问卷调查。对可能的危险因素进行多因素logistic回归分析。结果 60.9%的工人患有职业性肌肉骨骼疾患,其不同人体部位的患病率差异有统计学意义(χ2=617.466,P<0.01),腰部患病率最高(45.1%)。不同工种之间患病率差异有统计学意义(χ2=17.510,P<0.01)。进入回归方程的为工龄、工作疲劳感、自我健康状况评价、多次重复操作、不良体位、外伤史6个因素。结论所调查4个工厂的工人存在较严重的职业性肌肉骨骼损害。
Objective To investigate the prevalence of occupational musculoskeletal disorders among mechanical workers. Methods A cross-sectional survey method was used to investigate the musculoskeletal disorders in 990 workers from 4 mechanical processing factories in Fengtai District of Beijing. Multivariate logistic regression analysis of possible risk factors. Results 60.9% of workers had occupational musculoskeletal disorders. The prevalence of occupational musculoskeletal disorders was significantly different between the two groups (χ2 = 617.466, P <0.01) and the highest prevalence of lumbar (45.1%). The prevalence of different types of workers was significantly different (χ2 = 17.510, P <0.01). Into the regression equation for the length of service, work fatigue, self-health evaluation, repeated multiple operations, poor posture, history of trauma 6 factors. Conclusion The workers in the four factories surveyed had more serious occupational musculoskeletal injuries.
