Modulate Obesity and relateD metabolic complIcations For Yielding improvements in IBD outcomes (MODIFY-IBD):...

Obesity and related cardiometabolic comorbidities, including hypertension, dyslipidemia, diabetes, metabolic dysfunction-associated steatotic liver disease (MASLD), and atherosclerotic cardiovascular disease (ASCVD), are increasingly prevalent among individuals with inflammatory bowel disease (IBD). These conditions influence disease activity, therapeutic response, surgical outcomes, and overall quality of life, yet evidence remains fragmented. The Modulate Obesity and relateD metabolic complIcations For Yielding improvements in IBD outcomes (MODIFY-IBD) initiative aims to synthesize evidence and generate consensus recommendations to guide practice and future research in this area.

We will conduct a structured evidence review organized into three domains: (1) the impact of obesity on IBD outcomes (2) burden of cardiometabolic complications in IBD, and (3) management of obesity and cardiometabolic comorbidities in IBD. Draft clinical statements will be generated and evidence summaries prepared using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) framework, with certainty of evidence rated where applicable. In the assessment of those statements where GRADE is not feasible, a multidisciplinary international panel of gastroenterologists, surgeons, endocrinologists, hepatologists, cardiologists, and dietitians will assess each statement using the RAND/UCLA Appropriateness Method. Panelists will rate the appropriateness of each statement (only those that fall into their area of expertise) on a 1-9 scale (1-3 = inappropriate, 4-6 = uncertain, 7-9 = appropriate), with medians rounded up (e.g., 6.5 = appropriate). Agreement will be assessed using the RAND Disagreement Index (DI <1.0 = agreement).

This study will not involve direct patient participation, as it is based on evidence synthesis and expert consensus; therefore, formal Research Ethics Committee approval will not be required. Patient representatives will contribute to the consensus process to provide contextual perspectives, but no identifiable data will be collected.Findings will be disseminated through publication in peer-reviewed journals, presentation at major gastroenterology and IBD conferences, and communication with professional societies. A lay summary and patient-friendly infographic will also be developed to facilitate translation of recommendations into clinical practice.
