About

This study aims to conduct a proof-of-concept study to assess the feasibility, acceptability, and effectiveness of a Metabolic and bariatric surgery (MBS) -supported healthy lifestyle behavioral intervention among adolescent patients, their families, and their clinical team.

Full description

This proof-of-concept study aims to evaluate the feasibility, acceptability, and preliminary effectiveness of a lifestyle behavioral intervention integrated with metabolic and bariatric surgery (MBS) for adolescents with severe obesity. Targeting youth aged 12-18, the intervention is designed to enhance pre- and post-operative outcomes by supporting sustained healthy behaviors among patients and their families. Guided by formative qualitative research (AIM 1), the team will adapt an evidence-based multimedia lifestyle program (AIM 2) to align with adolescent MBS patients' unique needs and preferences.

The adapted intervention will then be pilot-tested (AIM 3) among adolescent patients at a large adolescent healthcare system, with participants followed up to 12 months post-surgery. The program includes online components delivered before and after surgery, with progress evaluated at multiple time points. In addition to anthropometric and cardiometabolic outcomes, the study will assess intervention engagement, satisfaction, and delivery fidelity using the RE-AIM framework. The overarching goal is to demonstrate that combining lifestyle support with MBS can improve adherence, reduce attrition, and enhance long-term health outcomes among adolescents with severe obesity.
