Introduction Integrated care aims to improve population health. Obesity and mental health are major health issues worldwide. The complexity of the multifactorial drivers of these public health problems has led to the adoption of a whole system approach. This review aims to highlight factors that influence the planning, implementation and evaluation of whole system integrated care for these conditions. Methods and analysis Using the framework of Arksey and O’ Malley, we will perform a comprehensive search in the following databases: MEDLINE, CINAHL, PsychINFO, PubMed, British Nursing Database, Web of Science, Health Systems Evidence, Cochrane Library and University of York Centre for Reviews and Dissemination. Further hand-search of reference lists and the grey literature will be conducted. The search will be restricted to articles published from 2000 to 2020. The review is expected to be completed by August 2021. Full texts of the potential studies will be screened for the inclusion criteria. Quality of studies will be appraised. Narrative synthesis will be completed using data extracted from the included studies. Ethics and dissemination A favourable ethics opinion for this study was obtained from the Institute for Health Research Ethics Committee of the University of Bedfordshire (IHREC937). This review expects to identify information relating to factors that facilitate or hinder whole system integrated care for obesity and mental health. The finding from this review will be widely disseminated to stakeholders to inform implementation of whole system integrated care initiatives.
