The first CDC state-specific estimates of the prevalence of a ≥7 hour sleep duration in a 24-hour period was reported in the MMWR. It showed geographic clustering of lower prevalence estimates for this duration of sleep in the southeastern United States and in states along the Appalachian Mountains. These are regions with the highest burdens of obesity and other chronic conditions. Non-Hispanic black, American Indian/Alaska Native, and Native Hawaiian/Pacific Islander, and multiracial populations report a lower prevalence of ≥7 hours sleep compared with the rest of the U.S. adult population. The highest prevalence was observed in the Great Plains states.
