机械行业工人肌肉骨骼损伤的调查

选择机械行业８７９名工人作为观察组，另选年龄、性别、工龄相近的９４６名行政管理人员作为对照组，通过询问调查及体验，观察组人员肌肉骨骼损伤的检出率显著高于对照组（Ｐ０．０１），且随着工龄延长而升高。体验的各种指标阳性率显著高于对照组（Ｐ０．０１）。患有肌肉骨骼损伤的观察组工人中有９０．３％的人认为长期固定的作业姿势是造成肌肉骨骼损伤的原因。提示：长时间固定的作业姿势是肌肉骨骼损伤的一个危险因素。

Epidemiological Investigation of Musculoskeletal Injury in Manufacturing Workers

manufacturing workers and 946 controls were selected for epidemiological investigation. The results shows that the prevalence rates of musculoskeletal injury in mechanical workers are higher than those in control group(P0.01). The prevalence rates increases with the length of service. The positive rates of some physical signs in manufacturing workers are higher too. Etiological analysis shows that the injury relating to fixed working posture is 90.3 percent. It indicates that prolonged and fixed posture and repetitive operation are the main causes of musculoskeletal injury.
