Abstract

OBJECTIVES: We studied the association between insomnia symptoms and late-life functioning, including physical capacity, limitations in household activities, and participation in valued activities.

METHODS: Participants were 6,050 adults independent in self-care activities from a representative sample of older Medicare beneficiaries. They completed objective measures of physical capacity and self-report measures of insomnia symptoms, help and difficulty with household activities, and participation in valued activities.

RESULTS: After adjustment, insomnia symptoms were associated with a greater odds of receiving help or having difficulty with selected household activities (laundry, shopping), greater odds of help or difficulty with ≥ 1 household activity [1 symptom vs. 0, odds ratio (OR)=1.27, p < .05; 2 symptoms vs. 0, OR = 1.35, p < .01), and of restricted participation in specific valued activities (attending religious services, going out for enjoyment) and in ≥ 1 valued activity (1 symptom vs. 0, OR = 1.29, p < .05; 2 symptoms vs. 0, OR = 1.50, p < .01). There was no independent association between insomnia symptoms and physical capacity.

DISCUSSION: Among older adults, insomnia symptoms are associated with a greater odds of limitation in household activities and of restricted participation in valued activities. Insomnia interventions may improve functioning and quality of life among elders.
