O-405 Occupational Health Risk Assessment on Back Pain and Its Associated Risk Factors Among Industrial Electronic Workers

Abstract Introduction Persistent back pain is common among industrial workers whose work involves materials handling and repetitive work. Some electronic workers perform sedentary and eye focusing work which might increase health risk. This cross-sectional study aimed to assess the occupational health risk and identify the risk factors correlated with back pain among electronic workers. Methods Data were collected on 354 workers with musculoskeletal disorders through a severity and frequency questionnaire (MSFQ), upper limb assessment of ergonomic risk and the measurement of lighting intensity at workstations. The occupational health risk matrix of back pain was applied by considering levels of back discomfort and ergonomic risk. Risk factors were identified by multiple logistic regression analysis. Results Most workers were female and had less than 5 years’ work experience. The lighting intensity at most inspected workstations with a microscope was lower than the standard requirement (76.52%). Ergonomic risk was high to very high for 57.63% of workers, with implementation needed. The occupational health risk matrix indicated that most workers had a moderate to very high risk of back pain (62.44%). Discussion Workers who performed eye focusing tasks in poor lighting intensity had high health risks. The significant risk factors of occupational back pain were the ergonomic conditions of workers performing manual lifting and shift work, and inappropriate workstation area. Conclusion These results suggest the ergonomic risk factors found to be associated with back pain should be improved and the occupational health risk matrix is useful for the surveillance of back pain and implementing preventive measures in industrial electronic workers.
