Abstract

Summary: Background: A gluten‐free diet treats coeliac disease, but its efficacy depends on strict adherence. A variety of patient factors may influence adherence but have not been well described at a population level. Aim: To comprehensively assess the patient factors that influence gluten‐free diet adherence in patients with coeliac disease. Methods: Patients with coeliac disease completed an online survey comprising the validated Celiac Dietary Adherence Test in addition to data on demographics, details of diagnosis and management and assessment of diet knowledge, quality of life and psychological distress. Survey data were analysed for predictors of adherence and quality of life. Results: Of 7393 responses, 5310 completed the Celiac Dietary Adherence Test and 3230 (61%) were adherent to a gluten‐free diet. Multivariate regression showed older age, being male, symptoms after gluten ingestion, better food knowledge and lower risk of psychological distress were independent predictors of adherence (each P ≤ 0.008). Additionally, dietary adherence was associated with better quality of life ( P < 0.001; multiple regression). Respondents who considered themselves to have poor food knowledge were more likely to incorrectly identify gluten‐free foods, but could still recognise gluten‐containing foods, suggesting that poor knowledge may lead to over‐restriction of diet. Conclusions: Poor knowledge of a gluten‐free diet and psychological wellbeing were independent modifiable risk factors for inadequate adherence to a gluten‐free diet in patients with coeliac disease. Involvement of both a dietitian and mental health care professional, in the presence of psychological distress, is likely to be necessary to improve adherence and health outcomes.

  • A well-informed patient is more likely to adhere to the GFD and to reconstruct normality.

    “A wellinformed patient is more likely to adhere to the GFD and to reconstruct normality (149, 150).”

    From ESPGHAN Position Paper on Management and Follow-up of Children and Adolescents With Celiac Disease. (2022) · cites this paper as [150]

    The Discussion reports that better food-knowledge scores independently predicted adherence to a gluten-free diet. The 'Predictors of poorer quality of life' section examines quality of life, but does not establish that better-informed patients are more likely to 'reconstruct normality'; knowledge was not listed among its significant predictors. Our copy provides no page numbers for these passages. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
