Abstract

The cross-sectional study aimed to investigate the relationship between work-related factors, perceived work fatigue (PWF) and musculoskeletal disorders (MSDs) among handicraft artisans. 364 artisans participated in a questionnaire survey, and a structural equation model (SEM) was developed to explore the direct and indirect relationships between these factors using partial least squares analysis. The SEM explained 98.2% of the variance in MSDs and revealed that exposure to biomechanical factors had a direct impact on PWF and MSDs, with PWF mediating the effect of biomechanical factors on MSDs. Additionally, job demand was found to be positively associated with MSDs, while job control and social support reduced the risk of MSDs. The findings underscore the importance of strategic initiatives to mitigate the risk of developing MSDs among artisans. The study also highlights the potential of SEM as a novel framework for understanding the complex pathogenesis of MSDs in occupational health research.Practitioner summary: The study sought to comprehensively examine the intricate relationships among work-related factors, PWF, and MSDs. To achieve this, an SEM approach was employed to capture both direct and indirect relationships between these factors, employing partial least squares analysis. Findings revealed SEM as an innovative framework for understanding the intricate development of MSDs.

手工艺工匠的工作相关因素、疲劳感和肌肉骨骼疾病之间的相互作用：结构方程模型分析。

这项横断面研究旨在调查手工艺工匠的工作相关因素、工作疲劳感（PWF）和肌肉骨骼疾病（MSDs）之间的关系。364 名手工艺者参与了问卷调查，并利用偏最小二乘法分析建立了结构方程模型（SEM），以探讨这些因素之间的直接和间接关系。结构方程模型解释了 98.2% 的 MSDs 变异，并揭示出生物力学因素对工作强度和 MSDs 有直接影响，而工作强度则是生物力学因素对 MSDs 影响的中介。此外，研究还发现工作需求与 MSDs 呈正相关，而工作控制和社会支持则降低了 MSDs 的风险。研究结果强调了采取战略措施降低工匠罹患 MSD 风险的重要性。该研究还强调了 SEM 作为一种新型框架的潜力，可用于了解职业健康研究中 MSDs 的复杂发病机制。为此，我们采用了 SEM 方法，通过偏最小二乘法分析来捕捉这些因素之间的直接和间接关系。研究结果表明，SEM 是理解 MSDs 复杂发展的创新框架。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
