Pediatric Avoidant-Restrictive Food Intake Disorder and gastrointestinal-related Somatic Symptom Disorders: Overlap in clinical presentation
Bibliographic record
Abstract
Certain presentations of Avoidant/Restrictive Food Intake Disorder (ARFID) and Somatic Symptom and Related Disorders (SSRDs) have conceptual overlap, namely, distress and impairment related to a physical symptom. This study compared characteristics of pediatric patients diagnosed with ARFID to those with gastrointestinal (GI)-related SSRD. A 5-year retrospective chart review at a tertiary care pediatric hospital comparing assessment data of patients with a diagnosis of ARFID ( n = 62; 69% girls, M age = 14.08 years) or a GI-related SSRD ( n = 37; 68% girls, M age = 14.25 years). Patients diagnosed with ARFID had a significantly lower percentage of median BMI than those with GI-related SSRD. Patients diagnosed with ARFID were most often assessed in the Eating Disorders Program, whereas patients diagnosed with an SSRD were most often assessed by Consultation-Liaison Psychiatry. Groups did not differ on demographics, psychiatric diagnoses, illness duration, or pre-assessment services/medications. GI symptoms were common across groups. Patients diagnosed with an SSRD had more co-occurring medical diagnoses. A subset (16%) of patients reported symptoms consistent with both diagnoses. Overlap is observed in the clinical presentation of pediatric patients diagnosed with ARFID or GI-related SSRD. Some group differences emerged, including anthropometric measurements and co-occurring medical conditions. Findings may inform diagnostic classification and treatment approach.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
