Late-life disability may increase with more frequent insomnia symptoms and sleep medications use over time.

ABSTRACT:

Study objectives

This study investigated whether disability status increased with the frequency of insomnia symptoms and sleep medication usage over a 5-year period and whether frequent use of sleep medication modified the longitudinal effects of insomnia symptoms on disability among community-dwelling older adults.

Methods

Data were from the National Health and Aging Trends Study (2011-2015; n = 6722). Disability was assessed with a validated disability index. Insomnia symptoms were assessed by the average frequency of longer sleep onset latency and trouble staying asleep. General sleep medication usage frequency was assessed. Multilevel modeling was used to analyze the data, considering health status, demographic information, and risky health behavior.
