Long working hours can lead to a variety of diseases, while the relationship between long work hours and multi-site work-related musculoskeletal disorders (WMSDs) remains unclear. This study aims to explore the association between working hours and multi-site WMSDs.
A cross-sectional study was conducted among 2636 transportation industry workers. The Nordic Musculoskeletal Questionnaire was used to assess musculoskeletal disorders. Workers were grouped by weekly working hours (≤ 40 h/wk, 40-55 h/wk, and ≥ 55 h/wk) to compare the prevalence of WMSDs. The correlation between different WMSDs sites and the influencing factors of multi-site WMSDs were analyzed by log-binomial model and logistic regression model.
897 (34.0%) participants faced long working hours. 995 (37.7%) participants suffered from WMSDs, while the highest prevalence of WMSDs symptoms occurred in neck (25.4%), followed by low back (18.4%) and shoulders (14.5%). Wrists WMSDs were associated with WMSDs in necks, shoulders, elbows, hips, and ankles (OR = 2.07-8.01). According to binary and multivariate logistic regression, the risk of WMSDs was higher in participants who worked 40-55 h/wk (OR: 1.30, 95% CI: 1.09-1.56) and more than 55 h/wk (OR: 2.15, 95% CI: 1.46-3.16) compared to participants who worked less than 40 h/wk. Additionally, participants who worked 40-55 h/wk (OR: 1.39, 95% CI: 1.09-1.78) and more than 55 h/wk (OR: 2.92, 95% CI: 1.82-4.70) were more likely to suffer from WMSDs in three or more sites.
Long working hours were positively associated with multi-site WMSDs. Early preventive and management measures of long working hours and WMSDs are of importance.
长时间工作可能导致多种疾病，而长时间工作与多部位与工作相关的肌肉骨骼疾病（WMSD）之间的关系尚不清楚。本研究旨在探讨工作时间与多部位 WMSD 之间的关系。
对 2636 名交通运输行业工人进行横断面研究。使用北欧肌肉骨骼问卷评估肌肉骨骼疾病。将每周工作时间（≤40 小时/周、40-55 小时/周和≥55 小时/周）的工人进行分组，以比较 WMSD 的患病率。使用对数二项式模型和逻辑回归模型分析不同 WMSD 部位之间的相关性和多部位 WMSD 的影响因素。
897 名（34.0%）参与者面临长时间工作。995 名（37.7%）参与者患有 WMSD，WMSD 症状的最高患病率出现在颈部（25.4%），其次是下背部（18.4%）和肩部（14.5%）。手腕 WMSD 与颈部、肩部、肘部、臀部和踝关节的 WMSD 相关（OR=2.07-8.01）。根据二项和多元逻辑回归，每周工作 40-55 小时（OR：1.30，95%CI：1.09-1.56）和超过 55 小时（OR：2.15，95%CI：1.46-3.16）的参与者发生 WMSD 的风险高于每周工作少于 40 小时的参与者。此外，每周工作 40-55 小时（OR：1.39，95%CI：1.09-1.78）和超过 55 小时（OR：2.92，95%CI：1.82-4.70）的参与者发生三个或更多部位 WMSD 的可能性更高。
长时间工作与多部位 WMSD 呈正相关。早期预防和管理长时间工作和 WMSD 非常重要。
