Area of Science:

  • Psychiatry
  • Pediatrics
  • Clinical Psychology

Background:

  • Avoidant/restrictive food intake disorder (ARFID) is a new diagnostic category in the DSM-5.
  • ARFID replaces the DSM-IV diagnosis of "feeding disorder of infancy or early childhood" but has no age restrictions.
  • Unlike anorexia nervosa and bulimia nervosa, ARFID is not characterized by body image disturbance.

Purpose of the Study:

  • To review the complex and heterogeneous etiology of ARFID.
  • To describe the characteristics, medical, and psychiatric comorbidities of ARFID patients.
  • To compare ARFID with other eating disorders and discuss evaluation and management strategies.

Main Methods:

  • Literature review of existing data on ARFID.
  • Comparison of ARFID characteristics and comorbidities with other eating disorders.
  • Discussion of current evaluation and management approaches.

Main Results:

  • ARFID has a complex and heterogeneous etiology.
  • Characteristics and comorbidities of ARFID patients are described and compared to other eating disorders.
  • Evaluation and management strategies are discussed.

Conclusions:

  • ARFID is a distinct eating disorder characterized by restricted intake without body image disturbance, affecting all age groups.
  • Further research is needed on ARFID's prognosis and prevention.
  • Recommendations for infant and child feeding practices are provided to guide parents.
