| Outline of Final Research Achievements |
We investigated the effects of the timing of meal intake, sleep, and physical activity on the diurnal 24-h rhythm of cardiac autonomic nervous system activity assessed by heart rate variability and subjective level of depressive symptoms. We found that later timing of breakfast was associated with a phase delay in cardiac autonomic nervous system activity and higher levels of the depressive symptoms in rotating shift workers. In addition, later timing of meal intake caused phase delay in the sleep-wake cycle and the temporal increase in subjective level of depressive mood. These results indicate the possibility that advancing the timing of meal intake after awakening is one of effective means for preventing a phase delay in the circadian clock and an increase in the depressive symptoms or mood in rotating shift workers.
