| Summary: | This study aims to investigate the prevalence and risk factors of
musculoskeletal disorders (MSDs) among South Korean male office workers and to
introduce a robust predictive model using the Robust and Sparse Twin Support
Vector Machine (RSTSVM). A cross-sectional survey was conducted among male office
workers in South Korea to assess the prevalence of MSDs and identify associated
risk factors. Data on ergonomic and psychosocial factors were collected and
analyzed. The RSTSVM model was developed and compared with traditional machine
learning models, including Support Vector Machine (SVM) and Gradient Boosting
Machine (GBM), to predict the risk of MSDs. The analysis revealed a high
prevalence of MSDs among the surveyed office workers, attributed to factors such
as prolonged sitting, repetitive hand/arm movements, standing posture and
carrying heavy objects. Prolonged static postures were significantly linked to
lower back pain and other musculoskeletal issues. Poor workstation ergonomics and
psychosocial stressors, such as high job demands and low job control, were also
identified as significant predictors of MSDs. The RSTSVM model demonstrated
superior performance in predicting MSDs, with an Area under the Receiver
Operating Characteristic Curve (AUC-ROC) value of 0.84, effectively managing
high-dimensional data and maintaining robustness against outliers and noise.
Furthermore, the RSTSVM model provided enhanced interpretability, making it
easier to identify and understand key risk factors compared to traditional
models. The study underscores the critical need for multifaceted intervention
strategies to address the ergonomic and psychosocial risk factors associated with
MSDs among office workers. Future research should focus on longitudinal studies
to establish causal relationships and evaluate the effectiveness of various
interventions across different occupational groups. |
