WASHINGTON: Nearly one in five Americans suffers from chronic "excessive sleepiness," according to a study presented today at the annual American Academy of Sleep Medicine meeting.
Researchers from Stanford University interviewed more than 8,000 adults about their sleeping habits, alertness, health and mental disorders. Of those, 19.5 percent fit the criteria for "moderate excessive sleepiness" and 17 percent of responders reported they had trouble staying awake and alert on the job, in meetings and in conversations.
"We have a problem in America with sleep," said Dr. Maurice Ohayon, principle investigator of the study and director of the Stanford University Sleep Epidemiology Research Center.
In 2002, Ohayon used the same techniques to study the general population in the United Kingdom, Germany, Italy, Portugal and Spain.
