Trial summary

The bariatric surgery is recommended for treatment of patients with severe obesity, resulting in greater weight loss and improvement of cardiovascular and metabolic comorbidities. However, weight regain is observed in patients after surgery, leading to health adverse outcomes. Read more about this study

About this study

Official title: Analysis of Weight Regain Rate and Predictive Factors in Patients Submitted to Bariatric Surgery.

The bariatric surgery is recommended for treatment of patients with severe obesity, resulting in greater weight loss and improvement of cardiovascular and metabolic comorbidities. However, weight regain is observed in patients after surgery, leading to health adverse outcomes. The purpose of this study is to identify the rate of weight regain and predictive factors of regain in bariatric patients without outpatients care regular.

Read the detailed description

Post-bariatric patients without care by health professional will be recruited. Patients will be divided, initially, in two groups by time after surgical procedure, as follows: Group 1≤ (G1≤) - patients that performed bariatric surgery for ≤ 1 year and Group 1> (G1>) - patients that performed bariatric surgery for > 1 year. Patients will be seen in a medical set for the first time at the Policlínica Piquet Carneiro (PPC) for outpatients care, which will consist of anamnesis and physical examination, obtaining demographic, socioeconomic data, medications and clinical history. The TxR will be calculated by [TxR = (current weight - minimum weight reported) x 100 / (weight preoperatively reported - minimum weight related)] and information on predictive variables for weight regain will be obtained by Alcohol Use Disorders Identification Test (AUDIT), Beck Depression Inventory (BDI), International Physical Activity Questionnaire (IPAQ), ActiGraph GT3X + accelerometer, 36-Item Short-Form Health Survey (SF-36), Eating Disorder Examination-Questionnaire (EDE-Q) and Repetitive eating questionnaire (REP(EAT) Q). The inclusion period of new patients in the PPC Obesity Clinic will be one year.

What is being measured

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

  1. Analysis of the association between weight regain and alcohol abuse disorder

    Analysis of the association between weight regain (weight in kg) and Alcohol abuse (avaliated by Alcohol Use Disorders Identification Test) in the first clinical evaluation

    Measured: through study completion, an average of 1 year

  2. Analysis of the association between weight regain and general psychopathology

    Analysis of the association between weight regain (weight in kg) and general psychopathology (avaliated by Beck Depression Inventory) in the first clinical evaluation

    Measured: through study completion, an average of 1 year

  3. Analysis of the association between weight regain and physical activity level

    Analysis of the association between weight regain (weight in kg) and physical activity (avaliated by International Physical Activity Questionnaire and the ActiGraph accelerometer) in the first clinical evaluation

    Measured: through study completion, an average of 1 year

  4. Analysis of the association between weight regain and quality of life indicators

    Analysis of the association between weight regain (weight in kg) and quality of life (avaliated by the 36-Item Short-Form Health Survey Questionnaire) in the first clinical evaluation

    Measured: through study completion, an average of 1 year

  5. Analysis of the association between weight regain and eating Disorder

    Analysis of the association between weight regain (weight in kg) and eating disorder (avaliated by Eating Disorder Examination-Questionnaire and Repetitive eating questionnaire) in the first clinical evaluation

    Measured: through study completion, an average of 1 year

The record says: finished, as of the sponsor's last update on 22 Mar 2022. 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 Brazil. 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?

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Analysis of the association between weight regain and alcohol abuse disorder (time frame: through study completion, an average of 1 year). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04193384, which also lists 1 linked publication.

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?
