Work Fatigue as a Mediator between Occupational and Lifestyle Factors and Blood Pressure among PLN Sulawesi Distribution and Load Dispatch Center Employees

Abstract

This study aimed to analyze the influence of Working Hours, Work Stress, Physical Activity, and Dietary Habit on Blood Pressure through Work Fatigue. This quantitative study used a cross-sectional design with path analysis. The sample consisted of 140 workers and employees of PT. PLN (Persero) UIP3B Sulawesi. Blood Pressure and Work Fatigue were measured directly, while Working Hours, Work Stress, Physical Activity, and Dietary Habit were obtained through questionnaires. The results showed that Working Hours significantly influenced Work Fatigue (p < 0.001), while its direct effect on Blood Pressure was not statistically significant at the 0.05 level, although it showed a borderline trend (p = 0.051). Work Stress significantly affected Work Fatigue (p = 0.017), but did not have a significant direct effect on Blood Pressure (p = 0.166). Physical Activity had no significant effect on either Work Fatigue (p = 0.652) or Blood Pressure (p = 0.915). Dietary Habit significantly influenced both Work Fatigue (p = 0.001) and Blood Pressure (p = 0.030). Furthermore, Work Fatigue significantly affected Blood Pressure (p < 0.001). In conclusion, Work Fatigue mediated the relationship between Working Hours, Work Stress, and Dietary Habit with Blood Pressure, while Physical Activity showed no significant direct or indirect effect. Dietary Habit indicated partial mediation because it had both significant direct and indirect effects on Blood Pressure.
