[Knowledge facilitates health: the "Fit in Health" program for strengthening the health literacy of students].

In Germany, more than half of the population has low health literacy. These people have difficulties in finding and classifying health-related information and adapting it to their own situation. Among them are many young people, highlighting the importance of interventions early in life to promote health literacy.This is where the "Fit in Health" program of the Health Information Services of the Helmholtz Munich Research Center and the German Cancer Research Center starts. The objective is to contribute to the promotion of different dimensions of health literacy among children and adolescents. To this end, innovative training formats for teachers and teaching materials for students at secondary levels I and II are being designed and evaluated. The major diseases cancer and diabetes mellitus are used as models to provide basic knowledge on their pathogenesis, prevention, treatment, and research. In addition, information about the structures of the healthcare system and materials to strengthen health literacy are provided. An accompanying evaluation collects indicator data on coverage and acceptance of the measures.Since 2018, the program has published 46 teaching materials and three course readers with background knowledge for teachers. Furthermore, 50 training courses have been held, with approximately 1600 teachers and multipliers taking part in face-to-face and online events by the end of 2021. More than 90% of the participants gave the respective events very good or good evaluations. Around 80% of the participants said they would like to include the topics taught in their lessons. Further expansion of the offers is planned. Testing of a set of materials with respect to the gain of health literacy in a sample of students is currently being prepared.
