Research Abstract	We performed an epidemiological study of centenarians in Okinawa and found that the prevalence values for difficulty initiating sleep (DIS), early morning awakening (EMA) and subjective insufficient sleep (SIS) were 21.7%, 12.8%, and 9.3%, respectively. Multiple logistic regression analysis revealed that hypertension was independently associated with DIS (adjusted odds ratio = 1.73 and 95% confidence interval : 1.07-2.79) The analysis also revealed that DIS was less frequent in persons whose daily activity was higher than that in others in their age group, suggesting that an active lifestyle was positively related to sleep in the very old.
