Abstract

Introduction: According to Centers for Disease Control and Prevention, Musculoskeletal Disorders (MSD) are diseases and discomfort which are caused by, or are related with injuries of muscles, tendons, joints, nerves, cartilage and spinal discs (CDC, 2022). The prevalence of Musculoskeletal Disorder (MSD) was relatively high in the modern society, which the recent analysis of Global Burden of Disease (GBD) from World Health Organisation (WHO) showed that around 1.71 billion people around the globe have musculoskeletal conditions (WHO, 2021). Musculoskeletal Disorder (MSD) are usually associated with work activities as causal factor. According to Department of Occupational Safety and Health, Malaysia (2021), occupational musculoskeletal disorders cases were 126 cases (3.2%) out of all 3890 occupational disease cases being reported in the year of 2017, which takes place as the second highest occupational disease amongst all. This situation indeed confirmed that musculoskeletal disorders (MSD) are a relatively common occupational disease among workers at the workplace. Thus, it is important for us to learn and discern the common symptoms and causes of Musculoskeletal Disorder (MSD) in order to prevent the workers to become a victim of it. Objective: To determine the association between the work-related and individual-related risk factors with prevalence of Musculoskeletal Disorders (MSD) among factory workers in Nilai, Negeri Sembilan. Methodology: The study design used for this research is cross-sectional study. The study location is located at Coca-Cola Far East Limited, Nilai, Negeri Sembilan during 1st August 2022 till 30th September 2022. 119 factory workers who aged between 18-60 years old and are full time workers were selected respondents. A set of self-administered questionnaire and Cornell Musculoskeletal Disorder Questionnaire (CMDQ) were distributed to obtain information from the respondents. Result & Discussion: Overall prevalence of MSD symptoms is high (91.4%) among the factory workers. The body part with highest prevalence of MSD is lower back (57.1%), followed by shoulders (55.2%) and upper back (50.5%). Majority of the factory workers are from age group of 30-39 years old (62.86%), followed by 40-49 years old (20.95%) and 18-29 years old (16.19%). Pearson’s Chi-Square test shown that age, gender, awkward posture and static and sustained posture had significant association with the development of MSD among the factory workers. The p-value for age is 0.030 (p<0.05), gender is 0.006 (p<0.01), awkward posture is 0.001 (p<0.01) and p-value for static and sustained posture is <0.001 (p<0.01). Multiple Logistic Regression result showed that male factory workers are 2.51 times (95% CI 1.791 – 3.540) more likely to develop MSD. Awkward posture can also increase the likelihood of factory workers to develop MSD at 8.090 times (95% CI 2.805 – 22.045). Lastly, static and sustained posture can increase the likelihood of developing MSD to 3.274 times (95% CI 2.134 – 4.741). Conclusion: The study outcome indicated that the prevalence of MSD was high (91.4%) among the factory workers. The significant risk factors that are associated with MSD are age, gender, awkward posture and static and sustained posture.
