Abstract: (1389 Views)
Background and Objective: Demanding and high-risk work environments, such as those in the railway industry, can significantly affect workers' occupational health. This study aimed to investigate occupational fatigue levels and their relationship with job strain, as defined by the Demand-Control Model, among railway maintenance workers.
Materials and Methods: This cross-sectional analytical study was conducted among railway maintenance workers in the southeastern region of Iran. Data were collected using standardized questionnaires, including the Job Content Questionnaire and the Swedish Occupational Fatigue Inventory 20, and analyzed with SPSS (version 26).
Results: The results showed that the mean occupational fatigue score was 43.99 ± 22.73, indicating a high level of occupational fatigue among the study participants. Among the five dimensions of occupational fatigue, "Lack of Energy" had the highest score, while "Physical Exertion" received the lowest. Based on the Demand-Control Model, although most participants were classified in the "active" group, workers in the "high-strain" group (high demand, low control) reported significantly higher levels of occupational fatigue.
Conclusion: The results show that holding jobs with high demands and low control are significant risk factors for occupational health fatigue. Therefore, designing organizational interventions to increase workers' authority and control over their tasks can effectively reduce occupational fatigue and promote occupational health.
