2347-P: Sleep Duration, Sleep Quality, and Associated Factors in a Nationally Representative Sample of U.S. Adults with Diabetes

Introduction and Objective: While the ADA guidelines have long focused on diet and exercise, sleep was added more recently as a key factor in managing diabetes. Long (>8 h) and short (<6 h) sleep durations and irregular sleep have been shown to negatively impact glycemia. Screening for sleep health is recommended for people with prediabetes and diabetes. However, little is known about the prevalence of sleep issues. This study aimed to examine sleep duration and quality, and to identify associated factors in a nationally representative sample of U.S. adults with diabetes. Methods: Data from the 2017-2018 National Health and Nutrition Examination Survey (i.e., the latest available NHANES year with measures of both sleep duration and quality) were used. Sleep duration was categorized into three groups: <6 h, 6-8 h, and >8 h. Poor-quality sleep was defined by the presence of any of the following: frequent snoring, frequent snorting/stop breathing, trouble sleeping, or excessive daytime sleepiness. Logistic regressions examined the associations of socio-demographic and clinical factors with poor sleep (sleep duration <6 or >8 h and/or poor-quality sleep) vs. good sleep (sleep duration 6-8 h and good-quality sleep). Results: The study sample included 797 adults with diabetes, representing approximately 26.8 million U.S. adults. Specifically, 8.7% had <6 h and 32.0% >8 h of sleep. Nearly three-quarters (73.2%) had poor-quality sleep (39.2% frequent snoring, 8.1% frequent snorting/stop breathing, 43.9% sleep trouble, 36.0% excessive daytime sleepiness). Overall, only 15.2% reported 6-8 h of good-quality sleep. Factors associated with poor sleep included A1C >9% (OR 2.06, 95% CI 1.08-3.93), obesity (OR 2.13, 95% CI 1.04-4.37), and hypertension (OR 2.71, 95% CI 1.52-4.83). Conclusion: Less than one-fifth of all adults with diabetes in the U.S. get an adequate amount of good-quality sleep. People with diabetes need screening for sleep health and referral to sleep specialists, especially those with type 2 diabetes, A1C >9%, obesity, and hypertension. Disclosure S.S. Kamal-Bahl: None.
