Evaluating eating behaviour, energy homeostasis, and obesity in childhood-onset craniopharyngioma: a feasibility study
Open accessPublished version of a preprint
Abstract
Introduction: Craniopharyngiomas are rare brain tumours (incidence 1.1–1.7 cases/million/year). Although non-malignant, craniopharyngioma causes major endocrine and visual morbidities including hypothalamic obesity, yet mechanisms leading to obesity are poorly understood. This study investigated the feasibility and acceptability of eating behaviour measures in patients with craniopharyngioma to inform the design of future trials. Methods: Patients with childhood-onset craniopharyngioma and controls matched for sex, pubertal stage, and age were recruited. After an overnight fast, participants received the following measures: body composition, resting metabolic rate, oral glucose tolerance test including magnetic resonance imaging (patients only), appetite ratings, eating behaviour, and quality of life questionnaires, ad libitum lunch, and an acceptability questionnaire. Data are reported as median ± IQR, with effect size measure (Cliff’s delta) and Kendall’s tau for correlations, due to the small sample size. Results: Eleven patients (median age = 14 years; 5 F/6 M) and matched controls (median age = 12 years; 5 F/6 M) were recruited. All patients had received surgery, and 9/11 also received radiotherapy. Hypothalamic damage post-surgery was graded (Paris grading): grade 2 n = 6; grade 1 n = 1; grade 0 n = 2. The included measures were deemed highly tolerable by participants and their parent/carers. Preliminary data suggest a difference in hyperphagia between patients and controls (d = 0.5), and a relationship between hyperphagia with body mass index standard deviation score (BMISDS) in patients (τ = 0.46). Discussion: These findings demonstrate that eating behaviour research is feasible and acceptable to craniopharyngioma patients and there is an association between BMISDS and hyperphagia in patients. Thus, food approach and avoidance behaviours may be useful targets for interventions to manage obesity in this patient group.

The effect of hyperphagia behaviors is decreased quality of life for affected individuals and increased burden for caretakers; obesity without hyperphagia does not have the same effects.
“The effect of these hyperphagia behaviors is decreased quality of life for affected individuals and increased burden for caretakers; obesity without hyperphagia does not have the same effects (84).”
From Approach to the patient with acquired hypothalamic syndrome (2026) · cites this paper as [84]
The Discussion (page not provided) reports that parents rated quality of life lower for young people with greater hyperphagic behaviours, but the young people’s own ratings did not show that relationship. The paper does not establish that hyperphagia causes lower quality of life, measure increased caretaker burden, or compare these effects with obesity without hyperphagia. (LLM, conf=0.88)
Experimental — accuracy not yet measuredIndividuals with hyperphagia spend more time "talking or engaging with food" than those without hyperphagia, and food interferes with daily functioning.
“Individuals with hyperphagia spend more time “talking or engaging with food” than those without hyperphagia, and food interferes with daily functioning (84).”
From Approach to the patient with acquired hypothalamic syndrome (2026) · cites this paper as [84]
The Results section ('Preliminary Data with Matched Controls') reports more time spent talking or engaging with food and greater interference with daily functioning in patients with childhood-onset craniopharyngioma than in matched controls. It also reports greater hyperphagia in the patient group, but it does not compare individuals classified as having hyperphagia with those without it. (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.
