Objective: The aim of this study is to analyze the relationships among personal factors, Working Ability Index (WAI), and Job Stress of tire manufacturing worker. Background: Musculoskeletal disorders are affected by not only physical factors such as repetitive movements, inappropriate postures, and handling heavy objects, but also mental factors such as work ability and job stress. The Work Ability Index (WAI) is a questionnaire tool developed for the purpose of evaluating and managing workers' work ability, and is evaluated by considering the worker's physical and mental qualities. Job stress is a physical and mental harmful reaction that occurs while performing a job and has a significant impact on work environment and health. Method: The survey was divided into three parts: personal factors, Work Ability Index (WAI), and Job Stress. The personal factors included 6 sub items: age group, years of work, leisure activities, diseases, previous injuries, and level of physical load. Statistical analyses were conducted to examine the relationships between personal factors and WAI (total score and subcategories), personal factors and Job Stress (total score and subcategories), and between WAI and Job Stress. Statistical analyses, including ANOVA and correlation analysis, were performed using SPSS (p<0.05). Results: WAI scores were significantly related to age group, disease, previous injuries, and level of physical load. Job stress scores showed significant differences across age group, years of work, leisure activities, and level of physical load. Conclusion: This study revealed significant relationships among personal factors, WAI, and job stress. However, there are limitations in generalization, because this study was conducted exclusively on tire manufacturing workers, its generalizability is limited. Thus, Further studies are needed in various industries. Application: Understanding the relationship between personal characteristics, work ability, and job stress can help identify workers at risk for musculoskeletal disorders and guide interventions, such as job rotation to prevent these disorders
