Hawai'i residents get sounder sleep than at least three other states, according to a new study by the Centers for Disease Control and Prevention.

The study released today shows about 38 percent of people in a survey here reported sleeping well during the past month. That compared to only about 28 percent of people in Delaware and Rhode Island and 29 percent in New York.

The report, based on telephone surveys conducted in 2006, also found a lower number of Hawai'i residents reported having sleep or rest problems during the past 30 days. Some 6,100 people in Hawai'i were interviewed.

It said only 8.8 percent of people here said they had insufficient rest or sleep every day during the past 30 days. That compared with 14 percent of people in Delaware.

Among the study also found that people tend to get more sufficient sleep the older they are and that people who were unemployed or unable to work scored higher in terms of having sleep or rest problems every night during a 30-day period.

Those who reported the least amount of sleep problems were retired people.
