Abstract
Oxidative stress in biological components has become recognized as one of the causative factors of various diseases. In this study, we investigated the effects of worker lifestyle and fatigue on the levels of urinary 8-hydroxydeoxyguanosine (8-OHdG), a marker of oxidative stress. Our results revealed that urinary 8-OHdG level was increased by alcohol intake and decreased by snack intake and adequate sleep time on the day before the survey. A decrease in urinary 8-OHdG level was also observed in parallel with a decrease in workload. Urinary 8-OHdG monitoring is expected to be useful for disease prevention in the future.
