Abstract

Introduction: Musculoskeletal disorder (MSD) is a common occupational disease reported in manufacturing sector. Identifying MSD risk factor is important to overcome the problem. Objective: This study was conducted to determine the association between musculoskeletal disorder (MSD) symptoms and risk factors among production workers in air conditioner manufacturing company. Methodology: A cross-sectional study design and stratified random sampling were used in this study. A total of 126 respondents participated in this study from five production lines. A validated Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) in Bahasa Melayu version was used to determine the prevalence of MSD symptoms. A set of self-administered questionnaires were used to determine sociodemographic factors, health factors, lifestyle factors, injury factors and occupational factors while Ergonomic Risk Assessment (ERA) was used to determine physical factors in each ergonomics risk factors that contribute to MSD symptoms. Statistical analysis was performed using chi-square test and multiple logistic regression. Results: The result showed that the prevalence of MSD symptoms among air conditioner production workers was 89.7%. The most common body parts reported with MSD symptoms were lower back (59.5%), right shoulder (57.9%) and upper back (54.8%). Chi-square test showed a significant association (p<0.05) between MSD symptoms and awkward posture, repetitive motion, static and sustained work posture, vibration and overtime work. Multiple logistic regression analysis revealed that workers that exposed to repetitive motion were 6.891 (95% CI 1.804 - 26.323) times more likely to experience MSD symptoms compared to workers not exposed to repetitive motion. Conclusion: It is concluded that the prevalence of MSD symptoms among air conditioner production workers was high due to awkward posture, repetitive motion, static and sustained work posture, vibration and overtime work which may contribute to the risk of developing MSD. Keywords: Musculoskeletal Disorder (MSD), risk factors, air conditioner manufacturing company, Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), Ergonomic Risk Assessment (ERA)
