Abstract Introduction Sleep duration has been associated with adverse health outcomes. However, few studies have investigated sleep duration trends over time and how these relate to race, income, education, and other factors. We investigated sleep duration trends from 2005 through 2014, inclusive, in the U.S. Methods A time trend analysis of self-reported sleep duration (hours) was performed in 30,238 adults (18–85 years) with National Health and Nutrition Examination Survey 2005–2014 data. Trend analyses were performed to evaluate the time trend of sleep duration for the following variables: sleep duration categorized as shorter (<7), normal (7-<9), longer (≥9) hours; sex, race, weight (underweight, normal weight, overweight, obese), income (low, medium, high), education (<high school (HS), HS, some college or graduate), age (18–44, 45–64, ≥65 years) and smoking (current vs. nonsmokers). Average sleep durations for these sub-populations were also examined. Given the complex survey design, sample weights were adjusted to produce accurate population estimates. Results From 2005 through 2014, average adult sleep duration was 6 hours 54 minutes. Significantly increased trends (P≤0.05) were found overall and in shorter sleepers, males, African-Americans (AA), those ≥65 years, those with low income, in high school graduates, and in overweight individuals. Average sleep durations’ significant (P≤0.05) patterns were as follows: females > whites; whites > other races (Mexican, other) > AA; aged ≥65 > 18–44 > 45–64 years; higher income > middle and low income; college or some college > high school or less; underweight > normal > overweight > obese; and non-smokers > smokers. Conclusion From 2005–2014, significantly increased sleep duration trends were found in the U.S. population overall and among shorter sleepers. Over nine years, males, African Americans, those with less than or high school education, low and middle income, and overweight populations demonstrated less average sleep, vis-a-vis their respective comparison groups, yet increased sleep duration trends, indicating time trends should be considered in analyses and interpretations of sleep duration data. Adults aged ≥65 years slept more on average and showed an increased sleep duration trend during this period. Support (If Any):
