Abstract:
To evaluate age‐related differences in sleep–wake symptoms. Design Cross‐sectional. Setting Technologist‐attended, laboratory‐based polysomnography ( PSG ). Participants Community‐dwelling adults aged 20 to 89 (N = 201): 52 aged 18 to 39, 72 aged 40 to 59, and 77 aged 60 and older. Measurements Medical burden (Charlson Comorbidity Index, medications, health status), PSG ‐defined sleep disorders (sleep‐disordered breathing ( SDB ), sleep‐associated hypoxemia, periodic limb movements in sleep ( PLMS )), sleep–wake symptoms (Epworth Sleepiness Scale ( ESS ), Insomnia Severity Index ( ISI ), fatigue (Facit‐F Scale)). Results Medical burden increased significantly with age (Charlson Comorbidity Index and number of medications, P 〈 .001; health status, P = .005). Severity of sleep disorders also increased significantly with age ( SDB and hypoxemia, P 〈 .001; PLMS , P = .008). Conversely, sleep–wake symptoms decreased with age (daytime drowsiness ( ESS ≥ 10), P = .02; insomnia ( ISI ≥ 8), P = .04; fatigue, P 〈 .001). In adjusted models, a 1‐year increase in age was significantly associated with a 4% decrease in the odds of having daytime drowsiness (odds ratio ( OR ) = 0.96, 95% confidence interval ( CI ) = 0.93–0.98). Similarly, but only in those with mild SDB , a 1‐year increase in age was significantly associated with a 5% decrease in the odds of having insomnia ( OR = 0.95, 95% CI = 0.92–0.99). Conclusion Older age was characterized by less‐severe sleep–wake symptoms (daytime drowsiness, insomnia, fatigue), despite an age‐related increase in disease severity (medical burden, sleep disorders). Because the increase in disease severity included well‐established risk factors for having sleep–wake symptoms, the age‐related decrease in sleep–wake symptoms may reflect a decrease in symptom awareness.
