Diagnosis
When diagnosing avoidant restrictive food intake disorder (ARFID), doctors take several criteria into consideration. These criteria include a lack of interest in food or avoidance of food due to texture, taste, or smell, inability to gain sufficient weight, interference with psychosocial functioning, and reliance on dietary supplements or tube feedings. In addition to a health history and physical examination, doctors may also conduct imaging and blood tests to identify any medical causes for weight loss or gastrointestinal discomfort, as well as to screen for nutritional deficiencies. While some children may require additional tests like endoscopy or brain imaging, doctors generally diagnose ARFID primarily through a health history assessment and physical examination.
Prevalence of Avoidant Restrictive Food Intake Disorder
Research indicates that while avoidant restrictive food intake disorder (ARFID) is equally prevalent among male and female infants and toddlers, it tends to become more common in boys during mid-childhood, particularly when it coexists with autism. Additionally, studies have revealed that ARFID often manifests at even younger ages, leading to delayed diagnosis compared to other eating disorders.
