In recent studies, ARFID shows a 4.0% prevalence among youth, yet clinical samples jump to 13%, with sensory-based avoidance often leading the pattern. Around 60% also report GI disorders and as many as 42% have anxiety, while autism, ADHD, and specific eating subtypes carve the differences. What looks like “picky eating” on the surface often tracks with measurable diagnostic criteria and targeted screening tools, so the overlap becomes harder to ignore.
