The paradigm shift from allergen avoidance to induction of tolerance early in life which occurred in the past decade means that the evidence base on which recommendations for prevention are based is changing causing uncertainty about the right strategies for prevention in both parents and health care providers. Both groups struggle to access, understand, appraise, and apply health information in order to make judgments and take decisions in everyday life concerning allergy prevention. This renders a thorough investigation of the perceptions and needs of both groups particularly important.


The aim of this sub-project is to explore parents' and health professionals' (HCPs') perceptions of the digital information environment on food allergy prevention and prediction. From this, recommendations for the development of digital health apps for parents and health professionals will be derived and finally the newly developed apps will be evaluated. The sub-project comprises 5 objectives or project parts:

  • Objective 1: Researching and understanding parental information needs and search (study "parents").
  • Objective 2: To explore and understand health care utilisation and health worker perspectives (GP study).
  • Objective 3: Exploring and understanding the digital information environment (Digital Information Study)
  • Objective 4: Triangulate the results of the "Parents", "GP" and "Digital Information" studies and integration of the results and development of recommendations (study "Recommendations")
  • Objective 5: Iterative evaluation of the apps in terms of user-friendliness and acceptance (study "Evaluation").


Recruitment and data collection for the "Parents" and "GP" study is currently taking place. You can find more information about this in here/follow/xx. In parallel, the digital information environment is being investigated.
