N2  - OBJECTIVES: The Centers for Disease Control and Prevention emphasizes conceptualizing sleep as a healthy behavior. Although a large literature exists documenting the morbidity or mortality of suboptimal sleep, fewer investigations have examined the burden of disease in a single number combining morbidity and mortality. This study examined the morbidity, as measured by health-related quality of life (HRQOL), mortality, and quality-adjusted life years (QALY) due to suboptimal (inadequate or excessive) sleep. DESIGN AND PARTICIPANTS: We ascertained respondents' HRQOL scores and mortality status from the 2005 to 2008 National Health and Nutrition Examination Survey (NHANES) with mortality follow-up data through December 31, 2011 for respondents aged 65 and older (n=2380). We estimated mean QALY according to duration of sleep, minutes to fall asleep, number of sleeping problems, and daytime impact. <br><br>RESULTS: More than one third of participants reported a suboptimal sleep duration. Short sleep duration had a greater adverse impact on morbidity, with reductions in HRQOL, while long sleep duration had a greater adverse impact on mortality. Compared to participants who reported between 7 and 9 hours of sleep per night, mean QALYs were significantly lower among participants who slept 10 or more hours a night (7.8 QALY; decrease of 9.8 QALY). <br><br>CONCLUSIONS: This study confirmed the association between suboptimal sleep and greater burden of disease among the elderly US population. Our findings provide support for treating sleep as a healthy (health risk) behavior, thereby having implications for primary care providers and public health surveillance.<br><br>Copyright © 2017 National Sleep Foundation.
