[Digital health literacy-conceptual contextualization, measurement, and promotion].

The concept of digital health literacy can be regarded as the result of the increasing social permeation of digital media and their use in everyday life. Due to increasing accessibility and ubiquity, there is an increasing need not only for searching and finding, but especially for assessing the reliability as well as selecting and applying health information for one's own health concerns. In the context of digitization, it needs to be emphasized that users are not just passive recipients, but rather actively participate in the communication process by interacting with existing content or by sharing their own health-related information.With particular focus on children and adolescents, this paper provides an overview of the current state of research on digital health literacy. In addition to its terminological and conceptual foundations and its links with media literacy, the relationship between digital health literacy and social and health inequality is discussed. Inequalities are not only generated by access to digital media but, above all, by the skills required for their use. After an overview of available instruments is provided, initial reflections on how to promote the individual and structural dimension of digital health literacy with focus on school settings is given.
