[Digital interventions in prevention and health promotion: What kind of evidence do we have and what is needed?]

Digital technologies increasingly affect our daily lives and interact with our living environment. A high potential for prevention and health promotion is referred to digital interventions. So far, however, there is a lack of well-founded evidence on the effectiveness of such measures. This paper will address the challenges of evidence-based digital interventions in prevention and health promotion. The results are summarised in the form of a narrative review.So far, evidence-based medicine methods have not been sufficiently used in the evaluation of benefits and harms in the field of prevention and health promotion. The reasons for this are found in the complexity of the corresponding measures. This complexity is further increased by digital interventions. Nevertheless, it is urgently recommended to place a stronger focus on evidence-based interventions in order to enable meaningful and comprehensible evaluation procedures with regard to the effectiveness of digital interventions in prevention and health promotion.Digitalisation leads to new demands on prevention and health promotion. A critical perspective on the actual impact of digital interventions and their social implications is needed. The development of a solid knowledge base is necessary in order to promote acceptance of the technologies and to achieve sustainable implementation.
