Circadian rhythm and quality of life in older adults.

Sleep is critical to physical and mental health for people of all ages, but older adults are particularly vulnerable to the consequences of poor sleep health. The purpose of this pilot study was to explore patterns of sleep and the relationships between circadian rhythm disorders and quantity of life in 34 community-dwelling older adults. Participants were primarily female, and single. Of participants, 44% reported poor sleep quality, and 29% had a circadian rhythm disorder. Those with circadian rhythm disorders had lower physical health quality of life score than other participants although this was not significant. No differences were seen in mental health quality of life scores. Further research is needed to explore sleep and circadian rhythm disorders in this population to target interventions to improve sleep quality.
