Analysis of influencing factors of multi-site musculoskeletal disorders among workers in the chemical pharmaceutical industry

Abstract

Objective To analyze the prevalence of multi-site work-related musculoskeletal disorders (WMSDs) and their influencing factors among workers in the chemical pharmaceutical industry.

Methods A total of 563 workers from three chemical pharmaceutical factories in Guangzhou City were selected as the research subjects using the judgment sampling method. The prevalence of multi-site WMSDs in the past 12 months was investigated using the electronic questionnaire of Chinese Version of Musculoskeletal Disorders Questionnaire.

Results The prevalence of multi-site WMSDs in the research subjects was 30.0% (169/563). The results of multivariable logistic regression analysis showed that workers who smoked regularly/frequently and those who had their hands above shoulder level for long periods of time had a lower risk of multi-site WMSDs than those who never/occasionally smoked (all P≤0.05). Workers with a high school, secondary specialty, college degree, or above had a lower risk of multi-site WMSDs than those with a middle school education or below (all P<0.05). The longer the daily working hours, the higher the risk of multiple WMSDs (all P<0.05). Workers with regular/frequently work shifts had a lower risk of multi-site WMSDs than those with none/occasional work shifts ( P<0.05).

Conclusion The prevalence of multi-site WMSDs among workers in the chemical pharmaceutical industry is relatively high. The influencing factors are individual factors, unreasonable work organization and poor ergonomics factors.

Abstract

摘要： 目的 分析化学制药行业工人多部位工作相关肌肉骨骼疾患(WMSDs)患病情况及其影响因素。 方法 采用判断 抽样方法, 选择广州市3家化学制药厂的563名工人为研究对象, 采用《中文版肌肉骨骼疾患调査表》电子问卷对其过去 12个月的多部位WMSDs患病情况进行调査。 结果 研究对象多部位WMSDs患病率为30.0%(169/563)。多因素 logistic回归分析结果显示, 经常/频繁吸烟和手长时间处于肩部以上者罹患多部位WMSDs的风险髙于从不/偶尔者( P值均≤0.05); 髙中及中等专科和大学专科以上的工人罹患多部位WMSDs的风险低于初中及以下者( P 值均<0.05); 日工作 时间越长者罹患多部位WMSDs的风险越髙( P 值均<0.05); 经常/频繁轮班者罹患多部位WMSDs的风险低于从不/偶尔 者( P<0.05)。 结论 化学制药行业工人的多部位WMSDs患病率较髙;其影响因素包括个体因素、不合理的工作组织和 不良工效学因素。
