Abstract:
Objectives. The prevalence rate of work-related musculoskeletal disorders (WMSDs) globally is notably high. There are a limited number of studies investigating WMSDs and their associated risk factors. However, there are currently no data available for WMSDs among industrial workers in Peninsular Malaysia. This study aimed to identify the prevalence of WMSDs and associated risk factors among industrial workers experiencing WMSDs through their daily working tasks. Methods. A quantitative study using a questionnaire was conducted among industrial workers from rehabilitation centres and factories in Peninsular Malaysia. The analysis of 232 participant narratives aimed to identify the correlation between job tasks and musculoskeletal pain, especially in case of repetitive and heavy handling tasks. Results. The prevalence of WMSDs among industrial workers stands at 93.1%. The results also indicate that the most affected part of the body was the lower back, with 62.1% for 7 days or more in the last year, caused by industrial workers' job tasks. The prominent risk factors associated with body parts include gender, age, working hours and most difficult tasks with MSDs, especially in the lower back. Conclusion. This survey helps us to understand whether the workers are experiencing any discomfort, pain or disability related to workplace activities.
Insights
Work-related musculoskeletal disorders (WMSDs) affect 93.1% of industrial workers in Peninsular Malaysia, with the lower back being the most impacted area. Key risk factors include gender, age, and long working hours.
Area of Science:
- Occupational health
- Musculoskeletal research
- Industrial hygiene
Background:
- Work-related musculoskeletal disorders (WMSDs) represent a significant global health burden.
- Limited research exists on WMSDs and their risk factors, particularly among industrial workers in Peninsular Malaysia.
Purpose of the Study:
- To determine the prevalence of WMSDs among industrial workers in Peninsular Malaysia.
- To identify risk factors associated with WMSDs in this population.
- To correlate specific job tasks with musculoskeletal pain.
Main Methods:
- A quantitative study was conducted using questionnaires.
- Data were collected from 232 industrial workers in rehabilitation centers and factories.
- Analysis focused on the relationship between job tasks (repetitive, heavy handling) and musculoskeletal pain.
Main Results:
- The prevalence of WMSDs was found to be 93.1%.
- The lower back was the most affected body part (62.1% reporting pain for 7+ days).
- Significant risk factors included gender, age, working hours, and task difficulty.
Conclusions:
- This study provides crucial data on WMSD prevalence in Malaysian industrial workers.
- Findings highlight the impact of job tasks on musculoskeletal health.
- Understanding these factors is vital for addressing worker discomfort and disability.
