Nutritional risks of ARFID (avoidant restrictive food intake disorders) and related behavior

Avoidant/restrictive food intake disorder (ARFID) has recently been added to the DSM V (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) as a new class of eating disorders (EDs). ARFID is characterized by a lack of interest in eating or avoiding specific types of foods because of their sensory characteristics. This avoidance results in decreased nutritional intake, eventually causing nutritional deficiencies. In severe cases, ARFID can lead to dependence on oral nutritional supplements, which interferes with psychosocial functioning. The prevalence of ARFID can be as high as 3% in the general population, and it is often associated with gastrointestinal symptoms and mainly appears in children with anxiety disorders. Given the high prevalence of ARFID, a rapid and systematic nutrition survey should be conducted during every pediatric consultation. Its treatment should also be adapted depending on the severity of the nutritional problem and may involve hospitalization with multidisciplinary care (pediatrician, nutritional therapist, dietitian, psychologists, and speech therapists)
