Abstract

This study examined the relationships of low cognitive performance and sleep disorder with functional disabilities among older adults. Methods: NHANES 2011–2014 data on 3179 individuals [Mage=69.71] were analyzed. Functional domains included: activities of daily living (ADL), instrumental ADL (IADL) and leisure and social activities (LSA). Animal Fluency Test and the Digit Symbol Substitution Test assessed cognitive performance. Participants self-reported having physician-diagnosed sleep disorder. Results: Participants with both low cognitive performance and sleep disorder had 4- to 10-times greater odds for ADL, IADL, and LSA difficulties compared to the participants with no low cognitive performance/sleep disorder. Participants with only low cognitive performance and those with only sleep disorder were two to three times more likely to experience these difficulties. Discussion: Low cognitive performance and sleep disorder together or independently were associated with functional disabilities. Participants with both low cognitive performance and sleep disorder had higher odds of functional disabilities.
