Avoidant/Restrictive Food Intake Disorder (ARFID)
An eating or feeding disturbance characterized by persistent failure to meet appropriate nutritional and/or energy needs. This leads to significant weight loss, nutritional deficiency, dependence on supplemental feeding, or marked interference with psychosocial functioning. Unlike anorexia nervosa, ARFID does not involve disturbance in body image or fear of weight gain.
Prevalence: 0.3-3% of general population. More common in children than adults. Equally common in males and females (unlike other eating disorders). Very common in children with autism (up to 50-70%).
