Forebygging av spiseforstyrrelser
An umbrella review is intended to summarize research on measures to prevent eating disorders. It is based on a previous research map, uses only systematic reviews of moderate or high quality, and assesses results using GRADE. The work has been commissioned by the Norwegian Directorate of Health as part of national efforts to prevent eating disorders.

Summary
We are conducting an umbrella review (review of systematic reviews) on the effect of interventions for preventing eating disorders. Eating disorders can be a severe condition both for the affected persons and their families. Studies on prevalence indicate an increase in prevalence of eating disorders, and this can have large socio-economic consequences. Prevention is thus warrented. We will assess the effect on disordered eating, eating disorder diagnoses, and body dissatisfaction. This umbrella review builds on an evidence and gap map on prevention and early intervention of eating disorders, published in 2025 at NIPH. The methodological quality of the systematic reviews in the evidence and gap map were assessed. If the newest systematic review was of high or moderate quality, we used that one. Otherwise, the next newest review with the same PICO (population, intervention, comparison, outcome) was assessed, and so on. We will in this umbrella review collect results on interventions for prevention of eating disorders from the systematic reviews of high or moderate methodological quality. We assess our confidence in the results using the GRADE approach. Our umbrella review is commissioned by The Norwegian Directorate of Health. The Norwegian Directorate of Health will provide an evidence synthesis on the prevention and treatment of eating disorders to the Ministry of Health and Care Services. This deliverable forms part of the assignment ‘Prevention and Treatment of Eating Disorders’ (TB2023-36), as outlined in Proposition 1 S (2022–2023). The assignment is further anchored in the Escalation Plan for Mental Health (2023–2033).
