What was done
Analyzed 2020 Behavioral Risk Factor Surveillance System (BRFSS) data to estimate the prevalence and geographic distribution of short sleep duration (<7 hours per day) among US adults aged 18 years or older across sociodemographic groups and US counties.
What was found
Nationally, 33.2% of US adults reported short sleep duration. Disparities were present across age, sex, race and ethnicity, marital status, education, income, and urbanicity (specific subgroup percentages were not reported in the abstract). Model-based county estimates showed the highest prevalence of short sleep duration clustered in the Southeast and along the Appalachian Mountains.
Why it matters
These findings provide updated population-level benchmarks identifying specific geographic areas and demographic subgroups most affected by insufficient sleep to guide targeted public health interventions.
Limits
Sleep duration was self-reported rather than objectively measured. The exact sample size and specific subgroup effect sizes were not provided in the abstract. The cross-sectional surveillance design cannot evaluate longitudinal trends or causality.
