Early detection of eating disorders: a scoping review

Abstract

Purpose: Early detection of eating disorders (EDs) could improve their prognosis, decrease morbidity and mortality, and prevent the risk of evolution towards a chronic form and somatic, psychiatric and psychosocial complications. The objective of this review was to examine the current scientific data concerning the early detection of EDs, which is one of the facets of secondary prevention.

Method: A scoping literature review was carried out following the PRISMA-ScR criteria, including all articles on ED detection published up to 2021 on PUBMED and PSYCINFO.

Results: 43 articles were included. Anorexia nervosa and bulimia nervosa were the most widely studied disorders. The articles focused on professionals from the medical field (GPs, psychiatrists, gynaecologists, gastroenterologists and residents), from the paramedical field, from education and sport, and from the general population. The assessments conducted with the professionals receiving interventions aiming to improve detection demonstrated their efficacy. Interventions for ED detection in the general population and at school seemed less efficacious.

Conclusion: The results highlighted some lines of action to be implemented. They pointed towards improving initial and continuing education for professional carers; e-learning could be an interesting solution for continuing education. Improving training with specific instructors, school personnel and sports professionals is also one of the solutions for a better detection of EDs. Specific recommendations could be published for fitness centre professionals to help them to deal with clients suspected of having an ED. Among secondary school students and in the general population, a better dissemination of mental health literacy and the development of mental health first aid programs could help improve early detection.

Level of evidence: Level I: Evidence obtained from systematic reviews.
