| description | Objectives
The purpose of this study was to explore the relationship between skeletal muscle disorders (SMD), occupational stress (OS) and depressive
symptoms (DS) among firefighters.
Material and Methods
A cross-sectional survey was conducted among firefighters in Chongqing, China.
Descriptive statistic and correlation analyses were performed by using SPSS 26.0. AMOS 24.0 was used to construct the structural equation modeling between SMD and DS. The mediating effect of OS was also evaluated.
Results
The results demonstrate that SMD can predict DS (β = 0.25,
p < 0.001) and OS (β = 0.39, p < 0.001) positively, OS positively predicted DS (β = 0.39, p < 0.001) after controlling for SMD. Additionally, OS has
a partial indirect effect between DS and SMD (indirect effects = 0.209, 95% CI: 0.093–0.372, p < 0.001).
Conclusions
Occupational stress has a partial
indirect effect between SMD and DS among firefighters. Skeletal muscle disorders could affect DS not only directly, but also indirectly, by affecting
OS. These findings may be of great significance and contribution to the future research of firefighters’ occupational health. Int J Occup Med Environ Health. 2025;38(1):18–29 |
