One of the most dynamically evolving sectors of our days is eHealth. More and more applications, software, devices, etc. are launched that make healthcare segments accessible not only for professionals but for laics, too. This study examines to what extent the adult Hungarian population of Mureş County is ready to become eHealth participative, i.e. an active agent of its own healthcare attendance, in order to make use of the advantages offered by modern technologies that provide information and help understand our diseases, their prevention, and health maintenance. The probability of eHealth usage is approximated by the frequency of Internet usage. Social determinants of info-communication tool usage are assessed, controlling for covariates. Age has the strongest impact upon the frequency of Internet usage. The younger is the respondent, the more likely he/she is to be a frequent user, and, apart from this, only the educational level determines Internet use, higher education implying more frequent usage.
