Study Objectives: Excessive daytime sleepiness is prevalent and overwhelmingly stems from disturbed sleep. We hypothesized that age modulates the association between excessive daytime sleepiness and increased all-cause mortality.

Methods: We utilized the Veterans' Health Administration data from 1999-2022.
