Abstract

Objectives: To determine the prevalence of sleep disorders in the United States and the association between sleep disorders and all-cause mortality.

Methods: A cross-sectional analysis of the 2009 to 2010 National Health and Nutrition Examination Survey (NHANES) and 2015 National Death Index (NDI) was performed. The 2009 to 2010 NHANES national household survey for adults ≥ 18 years was examined for the prevalence of sleep disorders as well as standard demographics and the presence of comorbidities (coronary artery disease [CAD], stroke, and emphysema). This dataset was linked to the 2015 NDI to associate the presence of sleep disorders with 5-year all-cause mortality.

Results: The study sample had a mean age of 46.1 years old, was 48.3% male, and had an average body mass index (BMI) of 28.7 (28.4-28.9). 7.1% (6.5%-7.7%) of adults reported being diagnosed with a sleep disorder, which represents an estimated 15.9 million (13.2-18.6) patients. The estimated mortality rate for those having a sleep disorder was 9.3% (7.2%-11.9%) compared to 5.2% (4.5%-5.9%) without a sleep disorder (odds ratio 1.89, P = <.001). After adjusting for age, sex, BMI, CAD, stroke, and emphysema, having a sleep disorder remained a significant predictor of increased mortality (hazard ratio, 1.5 [1.02-2.18], P = .042).

Conclusion: This study reports a high prevalence of self-reported but physician-diagnosed sleep disorders; however, this likely represents an underestimate. Given the association with all-cause mortality, there is a need for increased recognition of undiagnosed sleep disorders within the United States.

Level of evidence: 2b Laryngoscope, 131:686-689, 2021.
