Sleep is crucial for the physical, mental, and functional health of the older population. This cross-sectional study aimed to investigate the relationship between intrinsic capacity (IC) and sleep health and identify a cutoff score for sleep health to correspond to better IC in community-dwelling older adults. Participants were recruited from the community and outpatient clinics of a university hospital. Sleep health was assessed using the RU-SATED. IC was measured by the concept of integrated care for older people. Multiple linear regression determined relationship between IC and sleep health and use ROC curve to identify a cutoff score that correlated to better IC. 1,112 older adults (51.8% female sex) with mean age 72.4 years participated. Older people with an average sleep score of 9.85 points exhibited the worst in daytime sleepiness, sleep efficacy and sleep satisfaction. Male sex (β= 0.542, p= 0.002) and having fewer comorbidities (β= -0.160, p= 0.002), fewer pain complaints (β= -0.504, p< 0.001), and good IC (β= 0.899, p< 0.001) were significantly associated with better sleep health. Furthermore, better vision, hearing, and psychology capacities were positively correlated with better sleep health. A multidimensional sleep health score of ≥9.0 points was found to be a good cutoff value to correlate better IC. This study highlights the importance of addressing sleep health in older adults with impaired IC. Appropriate interventions to improve IC may promote better sleep health, especially in individuals with multidimensional sleep health scores less than 9.0 points.
