Young people use the internet on a daily basis to search for different types of information. Objectives. This research article seeks to analyse the attitudes and motivations of young people in relation to health information. Methods. The study is based on a semi-structured questionnaire survey applied to a sample of 250 university students, aged 18 to 24 years, from the Autonomous Communities of the Basque Country and Navarre, between 2014 and 2015. The survey results have a +/-95.5% confidence interval and a 3% margin of error. Results and Conclusions. Young people use the internet, mainly, to search for information, to communicate with friends and to obtain information to do their homework. Although they consult the internet, they prefer to discuss their health problems with their parents or friends. With regards to the roles they play on the internet, they define themselves as trolls, provocateurs, commentators, observers or creative users. Among the most reliable scientific sources of health information, they rely on books and specialised magazines, displacing newspapers and the internet to secondary positions.
