The Longitudinal Relationships between Multidimensional Sleep Health and Frailty among Community-Dwelling Older Adults: Evidence from Older Adults in Taiwan and the United States

The proposed research aims to investigate the longitudinal relationship between the multidimensional sleep health and frailty status among community-dwelling older adults. Our findings will contribute to the scientific literature and clinical practices and raise public awareness of the importance of sleep and its impacts on frailty. The understanding of the relationships among sleep health, physical activity, and frailty will aid in the prescription of the right intervention (e.g., behavioral intervention on sleep only, physical activity only, combined behavioral intervention on sleep and physical activities) to the right person at the right timing (e.g., individuals with worsening sleep health is likely to lead to a worsening frailty status). The findings from the proposed project will also help establish a sleep-frailty framework to be adopted in clinical practice. This framework will advise clinicians to incorporate regular sleep health screening as an indicator of imminent frailty episode followed by targeted interventions to avoid frailty onset or revert frailty transitions.
