     Many people turn to the web for health advice. Women use the Internet to look for health information

for themselves and their family significantly more than men, research has found. The study, by independent

research company Datamonitor, says that for this reason health sites should make greater efforts to appeal

to women by covering their health concerns.

     The researchers, who quizzed 4,531 adults across France, Germany, Italy, Spain, the UK and the US,

found that websites have become just as important as some off-line sources of health information. Fifty-seven

percent of those who looked for health information in the past 12 months consulted Internet sources.

     Report author Yvonne MacPherson said,"A distinct advantage of the Internet as a source of health

information is that information is easily accessible and can be read in private and at the leisure of the Internet

user." "Good health sites are not meant to replace interaction with a physician. Rather, they help patients

prepare for appointments and take more responsibility for their health." He added.

     Currently, 32-34% of adults aged 18 to 54 used the Internet to search for health information. This number

decreases to 27% in the 55 to 64 age group, and further to 14% in the 65 and over age group. Young Internet

users often conduct online health research on behalf of older family members who do not use the Internet.

     However, Datamonitor says that the audience for health information online will grow naturally as the

population ages, and more and more people grow up with the net. It recommends that website operators

focus their efforts on building a good long-term relationship with their existing consumers, rather than on

attempting to attract non-Internet users.
