Three studies being presented later this morning as posters examine the relationship between race and sleep.
One study (#0463) reports that race significantly influences the risk of obesity conferred by short sleep duration, with blacks having a higher risk than whites. Results show that the prevalence of both short sleep and obesity was higher in black Americans than in white Americans.
Another study (#0459) used the same sample to show that both short and long sleepers are at great risk for diabetes. The prevalence of diabetes was 12 percent for blacks and eight percent for whites.
A third study (#1197) shows that whites were more likely to report having excessive daytime sleepiness more than five days per month, but African Americans had a significantly higher risk of daytime sleepiness using the Epworth Sleepiness Scale.
