Eating disorders

We do research on the occurrence, causes and treatment of eating disorders.

The main research aims are investigating risk factors for eating disorders, and testing prevention and treatment programs for eating disorders among different groups. We use both qualitative and quantitative research methods

The research group is part of the Regional Section for Eating Disorders, Oslo University Hospital.

Projects

  • The NorMA study (Norwegian Microbiota Anorexia Nervosa) is a collaborative project with the Norwegian University of Environmental and Biosciences (NMBU) where the objective is to characterize the microbiota (gut flora) in patients with anorexia and in a control group, and investigate the relationship with gastrointestinal complaints and diet. It will also be investigated in the laboratory whether prebiotics can promote a "healthier" microbiota from patients with anorexia and create mouse models to test the use of prebiotics.
  • Oslo Bariatric Surgery Study (OBSS): A prospective study of cognitive functioning and physical activity before and after overweight surgery. One project examines cognitive functioning in patients before and after obesity surgery and one project investigates changes in physical activity over time after surgery.
  • Neuropsychological functioning in eating disorders: Several studies examining neuropsychological difficulties in patients with eating disorders.
  • Incidence of eating disorders: Cross-sectional study on the incidence of eating disorders in adolescents and incidence in the specialist health service using NPR data.
  • Body project: International multicentre study, on the effect of a preventive group-based intervention against eating disorders in young patients with diabetes.
  • Treatment of eating disorders: Studies the effect of Temperament based therapy with support (TBTS) for patients with anorexia, trial of Body project treatment manual for patients with eating disorders and group treatment of patients with binge eating disorder.
  • Validation of questionnaires / interviews used in the assessment and treatment of eating disorders
  • Risk factors for the development of eating disorders (EDGE project): Cross-sectional study with retroactive data on stressful life events where patients with eating disorders are compared with a control group. In addition, collected genetic information to investigate on gene-environment interaction for the development of eating disorders
  • Follow-up examination of patients treated at the child and adolescent unit at RASP: Follow-up study approx. 2.5 years after discharge, patients who have been treated at the child and adolescent unit at RASP are interviewed to describe the course and experiences of the treatment in both patients, siblings and parents.
