Almost one in five (19.8%) of the EU-15 population aged 15 years and over reported searching online for health-related information in the 12 months before the survey. Although this is a substantial figure, it is a lot lower than the more than two in five (44.9%) of the US sample who reported this form of eHealth activity. There were also considerable variations across European countries, ranging from more than one in three of the adult population in Denmark (34.7%) to about one in seventeen in Romania (5.9%). Although its importance varies across countries, online searching for health information is clearly becoming a significant element of the health-related activities of the population and needs to be given due attention in public health policy.
