Like for all eating disorders, the risk factors for ARFID involve a range of biological, psychological, and sociocultural issues. These factors may interact differently in different people, which means two people with the same eating disorder can have very diverse perspectives, experiences, and symptoms. Researchers know much less about what puts someone at risk of developing ARFID, but here’s what they do know:

  • People with autism spectrum conditions are much more likely to develop ARFID, as are those with ADHD and intellectual disabilities.
  • Children who don’t outgrow normal picky eating, or in whom picky eating is severe, appear to be more likely to develop ARFID.
  • Many children with ARFID also have a co-occurring anxiety disorder, and they are also at high risk for other psychiatric disorders.
