A rising global obesity epidemic in children has implications for an increase in other chronic diseases and a negative social impact, which should not be ignored. A useful resource in this context could be eHealth due to its popularity amongst children. Additionally, telephone guidance is also considered a powerful health promotion tool. The aim of this study was to investigate the availability of mobile applications (apps), websites, helplines, and advice lines for child obesity guidance, in European countries. A survey was conducted in 28 European Member States and 2 European Economic Area countries, in 2017. Twenty-three responses were collected. Fourteen countries stated the presence of an obesity management website.
