Abstract

Introduction: Musculoskeletal Disorder (MSD) is a leading cause of work-related health problems worldwide which generally multifactorial, comprises of socio-demographic factors, occupational factors and lighting condition. In Malaysia, the highest prevalence of MSD was found in manufacturing industry. Objective: This study aims to determine the factors associated with MSD symptoms among workers in the production line and to determine the illuminance level in an air conditioner manufacturing company in Bandar Baru Bangi. Methodology: A total of 126 assembly workers from five major production lines were scouted to participate in this study via stratified random sampling method. A Bahasa Melayu version of self-administered questionnaire, a Bahasa Melayu version of Cornell MSD Questionnaire (CMDQ-M), CRI Illuminance Meter CL-70F and a Digital Laser Meter OQX-40 was used for data collection. Chi-square test, mutiple logistics regression and Guideline on Occupational Safety and Health for Lighting at Workplace was used to determine the significant association with MSD symptoms, to determine the significant predictor of MSD symptoms and to compare the existing illuminance level with recommended illuminance level respectively. Results: The prevalence of MSD symptoms among the workers for the past work week was 89.7 %. Chi-square shows that MSD symptoms are significantly associated with perception on vibration (χ2 = 5.215, p = 0.022), perception on awkward posture (p = 0.022), perception on repetitive motion (p= 0.004) disturbing daylight (χ2 =7.272, p = 0.007) and lighting satisfaction (p = 0.000). Logistic regression indicates that MSD symptoms are associated with perception on repetitive motion (OR 6.127 (95% CI 1.514-24.806, p = 0.011) and lighting satisfaction (OR 16.922 (95% CI 3.217-89.028, p = 0.001). Conclusion: Chi-square test showed there are significant association between occupational factors (vibration, awkward posture and repetitive motion) and perception on lighting (disturbing daylight and lighting satisfaction) and MSD while multiple logistic regression showed perception on repetitive motion and lighting satisfaction are associated with MSD symptoms among the workers. Keywords:Musculoskeletal disorders, socio-demographic factor, occupational factor, lighting condition, manufacturing
