Fatigue

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Area of Science:

  • Occupational Health
  • Road Safety
  • Behavioral Science

Background:

  • Motorcycle food delivery workers face high accident risks, yet research often overlooks perceived risk, near-misses, and anxiety.
  • Safety concerns extend beyond traffic accidents to include psychological and experiential factors.

Purpose of the Study:

  • To investigate the association between occupational fatigue, health behaviors, and the Traffic Accident Risk Index (TARI) in South Korean delivery workers.
  • To analyze how fatigue and behaviors relate to near-miss experiences and accident-related anxiety.

Main Methods:

  • A cross-sectional study involving 336 South Korean delivery workers.
  • Data collected via online survey and analyzed using multiple linear regression.

Main Results:

  • Occupational fatigue correlated positively with overall TARI, near-misses, and accident anxiety.
  • Inconsistent helmet use, insufficient physical activity, and current smoking were linked to higher accident risk and anxiety.
  • Shorter break times were associated with lower accident risk and fewer near-miss experiences.

Conclusions:

  • Occupational fatigue is a significant factor in perceived accident risk, near-misses, and anxiety for delivery workers.
  • Modifiable health behaviors like helmet use, physical activity, and smoking cessation are crucial for improving safety.
  • Future research should focus on evidence-based rest guidelines and refining break time measurements.
