Risk Factors and their Interactions in VDT Workstation Systems

This study examined important risk factors and their interactions associated with physical symptoms reported by VDT users. A research model was developed. A survey was designed and conducted among 88 computer users. The results show that risk factors associated with various physical symptoms are different. Screen glare, awkward working posture, and fatigue are important factors related to physical symptoms. Psychosocial factors significantly interact with other variables, such as demographics variables, and contribute to awkward work posture and psychological stress. Workstation design variables significantly affect working postures.
