Prevalence and Geographic Patterns of Self-Reported Short Sleep Duration Among US Adults, 2020

Abstract

We estimated the prevalence of short sleep duration (<7 hours per day) among US adults aged 18 years or older by using 2020 Behavioral Risk Factor Surveillance System data. Nationally, 33.2% of adults reported short sleep duration. We identified disparities across sociodemographic characteristics, including age, sex, race and ethnicity, marital status, education, income, and urbanicity. Counties with the highest model-based estimates of short sleep duration clustered in the Southeast and along the Appalachian Mountains. These findings identified subgroups and geographic areas in which tailored strategies for promotion of optimal sleep duration (≥7 hours per night) are most needed.

Habitual Short Sleep Duration, Diet, and Development of Type 2 Diabetes in Adults

“…This cohort study assessing daily sleep duration, dietary habits, and the risk of T2D among individuals in the UK Biobank cohort 38 to 71 years of age found that habitual short sleep duration was associated with increased risk of developing T2D and that this association persisted even among participants who maintained a healthy diet. Many adults struggle to sleep 7 to 8 hours per day . As suggested by laboratory studies, a lack of sleep may contribute to the development of T2D through various mechanisms, such as impaired cellular insulin sensitivity, a skeletal muscle energy metabolism shifted toward nonglucose oxidation, increased activity of the sympathetic nervous system, and altered gut microbiota composition .…”

“…Many people sleep less than 7 hours per day, a condition often termed as short sleep duration. For instance, according to the 2020 Behavioral Risk Factor Surveillance System, 33.2% of US adults were short sleepers . Prolonged periods of insufficient sleep are associated with various health risks, including an increased risk of type 2 diabetes (T2D).…”

“…For instance, according to the 2020 Behavioral Risk Factor Surveillance System, 33.2% of US adults were short sleepers. 1 Prolonged periods of insufficient sleep are associated with various health risks, including an increased risk of type 2 diabetes (T2D). A meta-analysis of prospective studies involving 482 502 participants with follow-up periods spanning from 2.5 to 16.0 years demonstrated that each hour of sleep duration below 7 hours per day was associated with a 1.09-fold likelihood of developing T2D.…”

Association between sleep duration and hearing threshold shifts of adults in the United States: National Health and Nutrition Examination Survey, 2015–2016

“…Another sleep disorder is sleep duration. One third of the American adults reported shorter sleep duration than the amount recommended by the National Sleep Foundation [22]. Nonoptimal sleep durations have been correlated with adverse outcomes.…”
