Trends in prevalence of short sleep duration and trouble sleeping among US adults, 2005-2018.

STUDY OBJECTIVES

To determine trends in prevalence of short sleep duration and trouble sleeping among US adults from 2005 to 2018, and assess how sleep trends vary by sex and race/ethnicity.

METHODS

Seven cycles of the National Health and Nutrition Examination Survey (NHANES) data between 2005-2006 and 2017-2018 were analyzed. Trouble sleeping and sleep duration were self-reported. Short sleep duration was defined as sleep duration ≤ 6 hours. Age-standardized prevalence of reporting trouble sleeping to a health care provider and short sleep duration were estimated among the overall US adult population, and by sex and race/ethnicity.

RESULTS

From the 2005 to 2014, the age-adjusted prevalence of short sleep duration remained similar in the overall population (p for trend>0.05). Non-Hispanic Black people had the highest prevalence of short sleep duration among all race/ethnicity groups in all seven cycles. Prevalence of short sleep duration appears lower in 2015-2018 than in 2005-2014 due to different measurement methods applied. However, from 2005 to 2018, there were increasing trends in age-adjusted prevalence of reporting trouble sleeping to a health care provider in the overall population, among both men and women, and all race/ethnicity groups (p for trend<0.05). Among all the race/ethnicity groups, non-Hispanic White people had the highest prevalence of reporting trouble sleeping to a health care provider.

CONCLUSION

Findings depict the persistence of sleep-related issues in the US and possible risk factors, as well as racial disparities.
