Associations of Actigraphic Sleep Parameters With Fatigability in Older Adults.

ABSTRACT:

Background

Poor sleep may increase the likelihood of fatigue, and both are common in later life. However, prior studies of the sleep-fatigue relationship used subjective measures or were conducted in clinical populations; thus, the nature of this association in healthier community-dwelling older adults remains unclear. We studied the association of actigraphic sleep parameters with perceived fatigability-fatigue in response to a standardized task-and with conventional fatigue symptoms of low energy or tiredness.

Methods

We studied 382 cognitively normal participants in the Baltimore Longitudinal Study of Aging (aged 73.1 ± 10.3 years, 53.1% women) who completed 6.7 ± 0.9 days of wrist actigraphy and a perceived fatigability assessment, including rating of perceived exertion
