A19 THE IMPACT OF FOOD INSECURITY ON ADHERENCE TO A GLUTEN-FREE DIET IN THE ADULT CELIAC DISEASE POPULATION ATTENDING A DEDICATED CELIAC CLINIC
Bibliographic record
Abstract
Abstract Background A strict gluten-free diet (GFD) is currently the only treatment for celiac disease (CeD), but a GFD can be inconvenient and expensive. CeD patients who are food insecure (FI) face threats to GFD adherence, overall health, and quality of life. Aims To evaluate the prevalence of FI in patients with CeD attending a dedicated Adult Celiac Disease Clinic (ACDC) at an academic hospital and to examine the relationship between FI and GFD adherence, quality of life and various gastrointestinal symptoms. Methods Patients were invited to participate in the CeD registry when they attended the ACDC; those who agreed to participate then provided verbal and signed consent. Patients had the option to complete the CeD registry forms in the clinic on an iPad or at home using a card with a QR code and a unique ID to access the online CeD registry. The CeD registry uses REDCap (v. 11.1, 2021, US) and includes six validated questionnaires (Celiac Diet Adherence Test (CDAT), Celiac Disease Quality of Life Questionnaire (CD QoL), Celiac Symptom Index (CSI), Gastrointestinal Symptom Rating Scale (GSRS), Hospital Anxiety and Depression Scale (HADS), and Household Food Security Survey Module (HFSSM)). Continuous data are expressed as mean (SD), and categorical data as proportions of patients. The chi-squared test with Fisher correction and t-test were used to assess differences between groups. Results A total of 653 patients attended the ACDC from November 2, 2022, to September 20, 2023, and 411 patients were invited to participate in this study. Of them, 204 completed the CeD registry. Food insecurity was identified in 16% of CeD patients, of whom 11 (5%) were marginally FI, 16 (8%) were moderately FI, and 7 (3%) were severely FI. Compared to CeD patients who are food secure, a greater proportion of FI CeD patients reported nonadherence to GFD (26/34 vs 70/170; p<0.001), reduced QoL (32/34 vs 98/170; p<0.001), greater anxiety (27/34 vs 84/170; p=0.001) and greater depression (13/34 vs 26/170; p=0.004) compared with normal values. CeD patients with FI also reported lower QoL [61.0(14.9) vs 49.6(16.7); p=0.001] and increased gastrointestinal symptoms [GSRS 37.7(14.7) vs 29.0(12.8); p=0.001] compared with food secure CeD patients. Conclusions Food insecurity is common in patients with CeD and is associated with significantly worse adherence to treatment, symptom control, and quality of life. There is an important need for programs and societal measures to abolish food insecurity and ensure adequate access to treatment for patients with CeD. Funding Agencies TRIANGLE Summer Studentship

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.
