Multiple dimensions of sleep in relation to cognition: A nationally representative study of Asian, Black, Latine, and White US adults aged 40 years and older
Key Points
This research aims to explore the relationship between multiple dimensions of sleep and cognitive impairment in a diverse population of adults aged 40 and older.
Conducted a nationally representative observational study
Analyzed associations between sleep disturbances and cognitive function
Focused on Asian, Black, Latine, and White adults aged 40 and older
Found significant associations between sleep disturbances and cognitive impairment
Stronger associations were observed specifically among middle-aged adults
Recommendation for future studies to use objective measures to assess sleep
Abstract
Sleep disturbances were associated with cognitive impairment. Most associations were stronger among middle-aged adults, although future studies with objective measures are warranted.
