      Rosenvinge, Jan H; Pettersen, Gunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-09)
      The previous papers in this series outlined a historical panorama and presented updated knowledge about putative risk factors and how eating disorders are distributed in various populations. In this final paper, we discuss in what way comorbidity findings and transdiagnostic issues may change our conceptions about ‘an epidemiological case’ from the current definition of eating disorders based on the ...

    • Managing Risk of Non-Communicable Diseases in Women with Bulimia Nervosa or Binge Eating Disorders: A Randomized Trial with 12 Months Follow-Up 

      Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H; Bratland-Sanda, Solfrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-03)
      Persons with bulimia nervosa (BN) or binge eating disorder (BED) have an elevated risk of non-communicable diseases (NCDs). However, lowering this risk is rarely addressed in standard cognitive-behavioral treatment (CBT). We aimed to compare CBT with an intervention combining physical exercise and dietary therapy (PED-t), and hypothesized that the PED-t would do better than CBT in lowering the risk ...
