AbstractPurpose of review
Relapse is common in patients with anorexia nervosa. The aim of this study is to systematically review the existing literature on relapse in anorexia nervosa.Recent findings
A systematic literature search was conducted in PubMed, PsychInfo and CINAHL published up to April 2018. Of the 1527 studies screened, 16 studies were included in the present review.Summary
This analysis shows that, of the patients included in this review, 31% relapsed after treatment. The highest risk of relapse is during the first year after discharge and this risk continues for up to 2 years. An overview was made of all factors significantly associated with a higher risk of relapse, resulting in the following four clusters: eating disorder variables, comorbidity symptoms, process treatment variables and demographic variables. Future research on relapse prevention is necessary to further unravel the mechanisms that might lead to relapse.
