Analysis on influencing factors of leg work-related musculoskeletal disorders among shipbuilding workers

Abstract

Objective To investigate the current status and influencing factors of leg work-related musculoskeletal disorders (WMSDs) in shipbuilding workers.

Methods A total of 3 393 shipbuilding workers from Guangdong Province, Liaoning Province, Shandong Province, and Beijing City were selected as the research subjects using the convenience sampling method. The Chinese Version of the Musculoskeletal Disorders Questionnaire was used to investigate the prevalence of leg WMSDs in the past year. A multivariate logistic regression model was used to analyze the influencing factors of leg WMSDs.

Results The prevalence of leg WMSDs in the research subjects was 11.3% (382/3 393). The result of multivariate logistic regression showed that the risk of leg WMSDs was higher in workers with a length of service >10 years than those with a length of service <5 years ( P<0.05). Workers with frequent used of vibration tools at work had higher the risk of leg WMSDs (all P<0.05). Workers who did the same work every day, had insufficient rest time, had a shortage of department staff, and those who often repeated the same leg movements had a higher risk of leg WMSDs (all P<0.05). The risk of leg WMSDs in workers who sometimes stand for a long time was lower than that in workers who rarely stand for a long time ( P<0.01).

Conclusion Length of service, rarely longstanding work, use of vibration tools at work, daily engagement in the same work, in-adequate rest time, shortage of department staff, and frequent repetition of the same leg movements are all influencing factors for leg WMSDs in shipbuilding workers.

Abstract

摘要： 目的 调査船舶制造工人腿部工作相关肌肉骨骼疾患(WMSDs)的患病现状及其影响因素。 方法 采用方便抽样 方法, 选择广东省、辽宁省、山东省和北京市3 393名船舶制造工人为研究对象, 采用《中文版肌肉骨骼疾患调査表》调査 其过去1年中腿部WMSDs的患病情况, 采用多因素logistic回归模型分析其罹患腿部WMSDs的影响因素。 结果 研究 对象腿部WMSDs患病率为11.3% (382/3 393)。多因素logistic回归分析结果显示, 工龄>10年者罹患腿部WMSDs的风 险髙于工龄<5年者( P<0.05); 工作时使用振动工具越频繁者罹患腿部WMSDs的风险越髙( P 值均<0.05); 每天从事同样 的工作者、休息时间不充足者、部门人员短缺者、腿部经常重复同一动作者罹患腿部WMSDs的风险均较髙( P 值均<0.05); 有时长时间站立工作者罹患腿部WMSDs的风险低于很少长时间站立工作者( P<0.01)。 结论 工龄、很少长时间 站立工作、工作时使用振动工具、每天从事同样的工作、休息时间不充足、部门人员短缺和腿部经常重复同一动作等均是 船舶制造工人罹患腿部WMSDs的影响因素。
