| Outline of Final Research Achievements |
We investigated the characteristics of sleep patterns in frail and non-frail community-dwelling elderly. Furthermore, our study assessed posture allocations using two inclinometers during sleeping and waking periods under free-living conditions. Night-to-night wake time and mid-point sleep time were significantly associated with frailty. These findings suggest that sleep patterns might be an important modifiable factor associated with frailty development in elderly individuals. Additionally, women in this study spent significantly greater time lying down and standing still, and shorter time sitting during daily waking periods compared to their male counterparts. The results of our study suggest that use of two inclinometers may provide a valid estimate of posture allocation in free-living settings.
