An observational study in Binge-Eating Disorder, sponsored by Laval University. Recruiting at 2 sites in Canada. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2024-10-09.
Sponsored by Laval University · Observational
The investigators' hypothesis is that an improved assessment of the impulsivity-compulsivity spectrum, emotional regulation, attentional impairment and somatic or psychiatric comorbidities will result in a better distinction between the severe form of BED (e.g., highly impulsive and somatically complicated) from milder form (e.g., more compulsive and less somatically complicated).
233 studies on the registry are indexed under Binge-Eating Disorder; 53 are open to participants now.
This study's planned enrollment of 200 is above the median of 118 across 35 observational studies indexed under Binge-Eating Disorder.

Counted across the registry records on this site, refreshed daily.
Patients will be recruited from 2 sites: 1) the Institut Universitaire de Cardiologie et Pneumologie de Québec (IUCPQ; pre-bariatric surgery consultation and obesity care consultation); 2) the Centre d'Expertise Poids, Image et Alimentation (CEPIA), a clinic of the Institute of Nutrition and Functional Foods of Laval University (eatinig disorders consultation). The pre-selection of participants will be done using available data and screening tests deployed through the management frameworks already in place at the two sites. If needed, patients will be recruited by advertisement.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
BMI (body mass index)
