Interactions between work-related factors, perceived fatigue and musculoskeletal disorders among handicraft artisans: structural equation model analysis
本研究对364名手工艺工匠进行问卷调查，用结构方程模型分析发现生物力学因素直接影响感知疲劳和肌肉骨骼疾患，且感知疲劳起中介作用；工作需求增加患病风险，而工作控制和社会支持则降低风险。
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.
