Avoidant/restrictive food intake disorder

Abstract
Objectives: Eating disorders are common and serious conditions affecting up to 4% of the population. The
mortality rate is high. Despite the seriousness and prevalence of eating disorders in children and adolescents, no
Canadian practice guidelines exist to facilitate treatment decisions. This leaves clinicians without any guidance as to
which treatment they should use. Our objective was to produce such a guideline.
Methods: Using systematic review, the Grading of Recommendations Assessment, Development, and Evaluation
(GRADE) system, and the assembly of a panel of diverse stakeholders from across the country, we developed high
quality treatment guidelines that are focused on interventions for children and adolescents with eating disorders.
Results: Strong recommendations were supported specifically in favour of Family-Based Treatment, and more
generally in terms of least intensive treatment environment. Weak recommendations in favour of Multi-Family
Therapy, Cognitive Behavioural Therapy, Adolescent Focused Psychotherapy, adjunctive Yoga and atypical
antipsychotics were confirmed.
Conclusions: Several gaps for future work were identified including enhanced research efforts on new primary and
adjunctive treatments in order to address severe eating disorders and complex co-morbidities.
