Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patient starting follow-up at the Bariatric Medicine Clinic of the IUCPQ-ULaval.

To be included in the registry (database + biobank), a person must first be referred to the Bariatric Medicine Clinic at the IUCPQ-ULaval and meet several criteria:

  1. Be over 18 years of age
  2. Meet at least one of the following five criteria:
  3. Body mass index ≥30 kg/m2 with or without comorbidities (preclinical or clinical obesity);
  4. Require weight loss related to a transplant, bariatric surgery, or another type of surgery (e.g., hernia repair, orthopedic surgery, neurosurgery, etc.);
  5. History of bariatric surgery resulting in weight regain of at least 15% of the total weight lost;
  6. History of bariatric surgery resulting in weight loss deemed insufficient by the treating medical team;
  7. Having undergone bariatric surgery with complications related to it (i.e., flushing syndrome or hypoglycemia, nephrolithiasis, return of comorbidities in remission, abnormalities in phosphocalcic balance and vitamin deficiencies).

About this study

Official title: Database and Biological Material Bank in Obesity Medicine of the Quebec Heart and Lung Institute - Laval University (IUCPQ-ULaval)

Obesity medicine, or bariatric medicine, focuses not only on the biological and behavioral aspects, but also on the environmental and social factors that contribute to the development of obesity. Many diseases are associated with obesity, such as type 2 diabetes, hypertension, cardiovascular diseases, numerous cancers, gynecological disorders, etc. Focusing on obesity medicine is crucial for improving patients' quality of life, reducing healthcare costs, and developing effective prevention strategies. The Quebec Heart and Lung Institute - Laval University (IUCPQ-ULaval) maintains a clinical database and biological material bank for studying the multidisciplinary management of obesity and its complications.

A biobank is a collection of information, clinical or biochemical data (including radiological, cardiac, and genetic data), and blood samples concerning donors. The information that can be collected includes, for example, age, sex, diagnosis, progression or treatment of a medical condition, medications, DNA, etc. DNA is a molecule present in all cells and contains all the information necessary for the development and functioning of our body.

This bank aims to better characterize patients' profile receiving follow-up care in obesity medicine, identify predictive factors of success or failure of interventions and adapt management strategies according to specific needs. The collected data and blood samples will be used in several research projects with the following objectives:

  1. To document the socioeconomic, demographic, clinical, radiological, genetic, and biochemical characteristics of patients living with obesity and requiring medical follow-up at the bariatric medicine clinic at the IUCPQ-ULaval
  2. To explore the effects or associations of genetic and biochemical determinants on health in the context of obesity
  3. To gain a better understanding of the pathophysiology and genes involved in obesity and associated metabolic abnormalities
  4. To evaluate the clinical utility of non-invasive biomarkers in the screening of preclinical obesity and its comorbidities and/or
  5. To evaluate the effectiveness of medications, health behavior changes, and bariatric surgery in order to develop optimal interventions aimed at improving the health and medical management of people with obesity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Success or failure of obesity medicine interventions

    1. Anthropometric Parameters: weight and height combined to obtain BMI (kg/m^2). Waist circumference (cm); Body composition assessed by bioelectrical impedance analysis
    2. Cardiometabolic Parameters and Comorbidities: Hepatic steatosis and fibrosis assessed by controlled attenuation parameter (CAP) and liver stiffness measurement (transient elastography); Liver biochemical parameters (e.g., ALT, AST, GGT); Lipid profile (total cholesterol, LDL-C, HDL-C, triglycerides); Inflammatory markers (as available in medical records); Glycemic parameters (fasting glucose, HbA1c, insulin, as available); Polysomnography parameters (when available); Echocardiographic parameters (when available)
    3. Adoption of Lifestyle Intervention: Documented adherence and engagement in prescribed lifestyle interventions, as reported in medical charts
    4. Quality of Life: Clinician-documented quality-of-life assessment, as recorded in medical charts
    5. Mental Health Parameters: As recorded in medical charts

    Measured: Baseline to 15-year follow-up. Follow-up is based on standard care consultations which vary from a patient to another

Questions about this trial

What is this clinical trial studying?

An observational study of Obesity and Metabolic Abnormalities, run by Institut universitaire de cardiologie et de pneumologie de Québec, University Laval at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 16 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Audrey St-Laurent, PhD (418-656-8711 ext. 2681, audrey.st-laurent@criucpq.ulaval.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Success or failure of obesity medicine interventions (time frame: Baseline to 15-year follow-up. Follow-up is based on standard care consultations which vary from a patient to another). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2026.
