All models account for sampling weights and were adjusted for age, sex, ethnic background, site, income, education, and AHI. Sleep duration was modeled continuously. Napping was defined as more than one nap of at least 15 min over 1 week. Shift worker was defined as those working afternoon, night, split, irregular, or rotating shifts. Moderate to severe sleep apnea was defined as an AHI ≥15 events/hour. See Table 1 legend for expansion of abbreviations.
