Q: More than one in eight U. S. adults finds it hard to stay away from the Internet for several days at a time and about one in eleven tries to hide his or her online habit, according to a study showed on Tuesday.

The study involved a nationwide telephone survey of 2,581 respondents in the spring and summer of 2004 with researchers then examining the data and preparing the report which appears in the October issue of CNS Spectrums. The survey found that 68.9 percent of respondents were regular Internet users and 13.7 percent of the users found it hard to stay offline for several days at a time. It found 12.4 percent often stayed online longer than intended, more than 12 percent said they saw a need to cut back on their Internet use, and 8.7 percent tried to conceal "non-essential "Internet use from family, friends and employers. A smaller number, 8.2 percent, said they use the Internet to escape problems or a bad mood, while 5.9 percent felt their relationships suffered because of too much Internet use. One report published earlier this year said that 5 percent to 10 percent of the population likely will experience Internet addiction . It said signs include a disregard for health or appearance, lack of sleep and reducing physical activities and social communications with others, as well as dry eyes and juries of hands and fingers.
