Revision of ICD – status update on feeding and eating disorders

Abstract

The World Health Organization is currently revising the International Classification of Diseases and Related Health Problems (ICD-10). A central goal for the revision of the ICD classification of mental and behavioural disorders is to improve its clinical utility. Global representation and cultural sensitivity and relevance are important across all mental disorders, but are especially critical to advancing our understanding, diagnosis and treatment of feeding and eating disorders (FED). This paper summarises the current status of the Eating Disorders Consultation Group (EDCG) considerations regarding diagnostic categories for FEDs in ICD-11 and represents work in progress. The recommendations of the EDCG are informed by relevant research evidence, and the consultation group is striving to find a balance between clinical utility and diagnostic purity. Provisional recommendations of the EDCG include: (1) merger of previous FEDs categories in one group; (2) inclusion of six main FED categories that include anorexia nervosa (AN), bulimia nervosa (BN), pica, regurgitation disorder, binge-eating disorder (BED) and avoidant/restrictive food intake disorder, the last two representing new categories; (3) broadening of categories with the aim of reducing the use of the unspecified ED category (e.g. dropping the amenorrhea requirement, increasing the body mass index cut-off for low weight and rewording the cognitive and behavioural features of AN to be more culturally-sensitive). In line with this last recommendation, one point that require further analysis pertain to frequency and severity of the binge-eating and purging behaviours in BN and BED, as the EDCG is considering reducing or eliminating the frequency criterion and broadening the binge-eating criterion to include ?subjective? binge episodes.
