The latest Harris Poll, measuring how many people use the Internet to look for information about health topics, finds that the numbers continue to increase. The Harris Poll first used the word Cyberchondriacs to describe these people in 1998, when just over 50 million American adults had ever gone online to look for health information. By 2005, that number had risen to 117 million. In the new poll, the number of Cyberchondriacs has jumped to 175 million from 154 million last year, possibly as a result of the health care reform debate. Furthermore, frequency of usage has also increased. Fully 32% of all adults who are online say they look for health information "often," compared to 22% last year.

These are some of the results of The Harris Poll of 1,066 adults surveyed by telephone between July 13 and 18, 2010 by Harris Interactive.

Other findings in the new Harris Poll include:

* While the percentage of adults who go online (79%) has not changed significantly for several years, the proportion of those who are online and have ever used the to look for health information has increased to 88% this year, the highest number ever.

* Fully 81% of all Cyberchondriacs have looked for health information online in the last month. And 17% have gone online to look for health information ten or more times in the last month. On average, Cyberchondriacs do this about 6 times a month.

* Very few Cyberchondriacs are dissatisfied with their ability to find what they want online. Only 9% report that they were somewhat (6%) or very (3%) unsuccessful. And only 8% believe that the information they found was unreliable.

* Just over half (53%) of all Cyberchondriacs report that they have discussed information they found online with their doctors.

* Half (51%) of all Cyberchondriacs say they have searched for information on the Internet based on discussions with their doctors.
