Obesity Clinical Trial - Evaluation of a Lifestyle Intervention After

Status Completed

Clinical Trial Summary

The aim of this trial is to evaluate the effect of a post-surgery 12-month lifestyle intervention compared to usual care upon post-surgery weight loss and changes that occur in body composition (relative amounts of body fat, muscle and bone), physical fitness and activity levels, diseases linked to obesity (e.g. diabetes, high blood pressure, high cholesterol level, sleep apnoea) and health-related quality of life (HRQoL) over a 12-month period.

Clinical Trial Description

People with severe obesity who are scheduled to undergo either primary gastric bypass or primary sleeve gastrectomy will be recruited from the Bariatric Clinics at University College London Hospital (UCLH) and the Whittington Hospital and asked to participate in an observational cohort study. Eligible patients will be given a participant information sheet (PIS) for BARI-LIFESTYLE Observational Study and informed consent will be sought. Recruited patient will attend for 4 research visits, timed to coincide with their clinic visits, at approximately 6 weeks before surgery (Visit 1), 3 month post-surgery (Visit 2), 6 months post-surgery (Visit 3) and 12 months post-surgery (Visit 4). Each research visit will include assessment of body weight, body composition (using bioelectrical impedance analysis), physical fitness and activity levels, obesity-associated co-morbidities, HRQoL and usual care laboratory investigations. Dual energy X-ray absorptiometry (DXA) scanning will be undertaken at Visit 1 and Visit 4, which is not a usual assessment for the post-surgery standard care. All of the research assessments will be done as part of this observational cohort study. Immediately after surgery has been undertaken, BARI-LIFESTYLE Observational Study participants will be randomised to continue to receive usual care, or usual care plus lifestyle intervention (nutritional and behavioural tele-counselling, self-monitoring and a 12-week supervised tailored exercise programme). However, to avoid contamination between the intervention group and the usual care group, only those randomly allocated to the lifestyle intervention group will be informed of this. They will be given a PIS (BARI-LIFESTYLE Intervention Study) and informed consent will be sought. If the participants decline to take part in the lifestyle programme, they will remain in the control group (observational cohort study). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
