Celiac Disease and Inflammatory Bowel Disease Are Associated With Increased Risk of Eating Disorders: An Ontario Health Administrative Database Study
Bibliographic record
Abstract
INTRODUCTION: Previous national registry studies have reported an increased risk of eating disorders in immune-mediated conditions (inflammatory bowel disease and celiac disease). Our objective was to examine the association between immune-mediated gastrointestinal (GI) diseases and incident eating disorders in Ontario. METHODS: This was a retrospective matched cohort study of individuals <50 years of age with a diagnosis of an immune-mediated GI disease between 2002 and 2020 ("cases"). Those with a pre-existing eating disorder were excluded. Cases (n = 83,920) were matched with controls (n = 167,776) based on birth year, sex, and region of residence. Incidence rate ratio and hazard ratio were estimated using Poisson regression model and adjusted Cox proportional models, respectively. RESULTS: Over the follow-up period (up to January 31, 2022), 161 cases and 160 controls were identified with eating disorders. The overall incidence rate ratio (95% confidence interval, P -value) of eating disorders in immune-mediated GI disease was 1.99 (1.6-2.5, P < 0.001). The adjusted hazard ratio for eating disorder in cases with immune-mediated GI diseases was 1.98 (1.6-2.5, P < 0.001). In the pediatric group of incident cases (≤18 years of age), overall adjusted hazard ratio was 2.62 (1.9-3.7, P < 0.001) compared with 1.56 (1.02-2.4, P = 0.041) for adults (>18 years of age). The largest hazard ratio of 4.11 (1.6-10.3, P = 0.003) was observed for pediatric incident cases of ulcerative colitis. DISCUSSION: Inflammatory bowel disease and celiac disease are associated with the development of eating disorders. The magnitude of the association was stronger in the pediatric age group, underscoring the need for early screening and detection.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
