Background: Knee pain is one of the most common musculoskeletal pains at workplace and its prevalence ranges from 10 to 60%. Risky work behaviors are established risk factors. They result in functional impairment, disability and reduce quality of life. Objectives: This study aims to determine the relationships between risky work behaviors and knee AL-Dubai et al.; BJMMR, 10(3): 1-9, 2015; Article no.BJMMR.19097 2 pain among Malaysian railway workers. Materials and Methods: A cross-sectional study was carried out on 513 railway workers across eight states within Peninsular Malaysia. Socio-demographics, risky work behaviors, occupational safety and history of knee pain were obtained by direct interviews using a structured closed ended questionnaire. Descriptive, bivariate and multiple logistic regression analyses were performed. Results: The prevalence of self-reported knee pain over the past one year was 31.6%. Multivariate analysis yielded six significant predictors of knee pain: Socio-demographics (tertiary education); risky work behaviors (lifting or carrying heavy objects, working in uncomfortable position of knee joint, repeated flexion and extension of knee joint, continuous sitting work); and occupational safety (applying Personal Protective Equipment - PPE during work). Conclusion: The significant associations between knee pain and risky work behaviors in railway workers point to urgent need for preventive measures, particularly in high risk occupations.
