Abstract
Background: Numerous studies have reported the relationship between sleep duration and obesity in elderly adults; however, little is known about the relationship of sleep duration and sarcopenia. Objective: We examined the relationship of sleep duration with obesity and sarcopenia in community-dwelling older adults. Methods: A total of 488 community-dwelling adults (224 men and 264 women) aged ≥65 years were included in the analysis. Self-reported sleep duration and anthropometric data were collected. Skeletal muscle mass was estimated using the predicted equation from a bioelectrical impedance analysis measurement. Obesity and sarcopenia were defined according to the body mass index and the skeletal muscle mass index, respectively. Results: The association between sleep duration and sarcopenia exhibited a U shape in older adults. Compared to adults with 6-8 h of sleep, adults with Conclusion: There were significant associations of sleep duration with either obesity or sarcopenia in community-dwelling older adults. Gender differences in these associations were also observed.
