Level 4 - case-series / case-control
Cross-sectional survey analysis
What was done
CDC analyzed cross-sectional survey data from a sleep module added to the Behavioral Risk Factor Surveillance System (BRFSS) in 2009 to assess the prevalence of selected sleep difficulties and behaviors across 12 US states.
What was found
Among 74,571 adult respondents across 12 states: - 35.3% reported sleeping <7 hours on average per 24-hour period. - 48.0% reported snoring. - 37.9% reported unintentionally falling asleep during the day on at least 1 day in the preceding 30 days. - 4.7% reported nodding off or falling asleep while driving in the preceding 30 days.
Why it matters
It provides multi-state public health surveillance data showing that short sleep duration, daytime sleepiness, and drowsy driving were prevalent among US adults in 2009.
Limits
Data are cross-sectional and rely entirely on self-report without objective validation; results represent only 12 states rather than the entire US population.
