Obesity is a complex health issue that affects nearly 30% of XXX. Beyond its clinical definition, people living with obesity (PLWO) face persistent social and structural barriers that negatively impact their well-being. Given that healthcare influences only about 20% of health outcomes, interventions must prioritize partnerships beyond the healthcare system. In this context, a participatory research initiative was launched, led by a citizen and a researcher, to co-create the first intersectoral learning community for, with, and by PLWO in a rural region of XXX.To analyze the impacts of partnership-based action during co-design workshops aimed at jointly developing an intersectoral learning community.From March to November 2025, four co-design workshops (three in person, one online) were conducted with 22 participants from health, community, and municipal sectors, alongside PLWO. A participatory qualitative design using participant-observation examined interaction and collaboration dynamics. Bilodeau’s model of six conditions for successful intersectoral action guided the analytical framework. Data collection included structured observation grids, field notes, and audio recordings. Thematic coding was performed using NVivo with a deductive, triangulated analysis approach.Workshops demonstrated strong engagement and evolving collaborative dynamics. PLWO initiated most discussions and displayed significant leadership. Exchanges shifted from general reflections to context-specific solutions. Online participation generated less engagement, highlighting the importance of in-person interaction. The use of persona-based facilitation grounded discussions in lived experience and stimulated creative, solution-oriented dialogue. Tangible emerging collaborations, particularly between health and community sectors, were observed. Participants mapped existing local initiatives and developed new partnerships beyond workshop sessions, revealing both the potential and the fragility of sustained engagement in rural contexts.Limitations relate to implementation in a rural region where stakeholders are already involved in multiple projects, which may influence engagement. The study highlights the strengths of flexible facilitation and methods tailored to diverse stakeholders, fostering shared understanding and helping bridge sectoral boundaries.This study illustrates how structured participatory approaches can strengthen person-centred, equitable, and integrated care for PLWO. The model offers transferable lessons for intersectoral initiatives seeking to embed co-design with people with lived experience and address other complex health issues requiring cross-sector collaboration.

Obesity is a major global health challenge influenced by genetic, behavioral, socioeconomic, and environmental factors. Although healthcare influences only 20% of health outcomes, most interventions still focus on weight rather than broader social determinants of health (SDH). Addressing obesity effectively requires intersectoral approaches bridging health, social, community, and policy domains. Launched in 2023 by a citizen partner and a clinical researcher, the XXX participatory research initiative aims to co-develop an intersectoral learning community for, with, and by PLWO to better meet their needs. Given limited data on intersectoral engagement, a preliminary environmental scan was conducted.To identify and characterize intersectoral interventions targeting PLWO in community and primary care settingsFollowing Arksey and O’Malley’s framework, a comprehensive search was conducted across three academic databases and grey literature sources (May 2024-February 2025). Eligible records described intersectoral interventions for adults in XXX countries (since 2006, English or French). Data extraction followed an adapted conceptual framework based on SDH and was synthesized according to PRISMA 2020. Bibliometric mapping using VOSviewer® refined the conceptual mapping.23 of 6876 studies (20 peer-reviewed, 3 grey literature), mainly from the United States and focused on lifestyle modification programs. Obesity was primarily defined using weight-based metrics with little consideration for SDH. None explicitly defined intersectorality. Collaborations mainly involved health, academic, community, and faith-based sectors, with community health workers emerging as essential connectors between clinical and social domains. Outcome measures remained largely biomedical, with minimal integration of SDH indicators. The results highlight the need to integrate social determinants of health into evaluation frameworks, formalize intersectoral governance, and institutionalize community health workers to promote equity and person-centered care.This first environmental scan on intersectoral interventions for PLWO provides new insights into how collaborative approaches are designed, implemented, and evaluated. While the focus on high-income countries and English/French sources may have limited cultural diversity, including grey literature, strengthened contextual understanding. The strength of this study lies in the bibliometric analysis, which reinforces the qualitative data extracted.These insights will guide the XXX learning community in developing co-creation workshops that promote integrated, sustainable intersectoral strategies for obesity management.

Obesity remains a significant public health challenge in Europe, affecting both adults and children and adding pressure on primary health care (PHC) systems. Although behavioural, nutritional, digital, and pharmacological interventions are available, their integration into routine PHC is uneven. Persistent gaps between guidelines and practice underscore the need to understand the real-world barriers and facilitators shaping obesity care delivery.This scoping review aims to identify key factors that hinder or support the implementation of obesity management interventions in PHC and to inform practical strategies, training needs, and system-level supports for more effective, person-centred obesity care.The review is being conducted according to PRISMA-ScR guidelines and PICOS-based criteria. Searches were carried out across PubMed (n=206), Web of Science (n=386), Scopus (n=212), ScienceDirect (n=192), and the Cochrane Library (n=92), covering publications from 2019–2025 in seven languages. After removing 422 duplicates, 665 records underwent title and abstract screening, with 293 excluded. In total, 372 full-text articles were sought for retrieval and are currently under assessment. Eligible studies include adults or children with overweight or obesity in PHC and address lifestyle, behavioural, nutritional, pharmacological, digital, or system-level interventions. Grey literature, theses, and policy reports were included to ensure comprehensive coverage. The protocol is registered with the Open Science Framework.Preliminary findings point to several recurring challenges: regulatory and financial barriers to pharmacological treatments; limited time and resources in consultations; insufficient training for PHC teams; and the persistent role of stigma in shaping communication and patient engagement. Facilitators include structured clinical pathways, multidisciplinary teamwork, adoption of person-first language, and increasing use of digital tools to support follow-up and self-management. PHC professionals consistently emerge as central coordinators of long-term obesity care.Early evidence shows that barriers span patient, provider, and system levels, indicating a need for better alignment between policy commitments, clinical guidance, and day-to-day PHC operations. Strengthening training, organisational support, and access to treatments may enhance intervention uptake and fidelity.This review will synthesise current evidence to guide the development of actionable and scalable strategies that reinforce obesity management in PHC and support more equitable, person-centred, and sustainable obesity care across Europe

Prediabetes is a growing global challenge, with most cases diagnosed and managed in primary care. Lifestyle modification—particularly weight reduction—is central to delaying or preventing progression to type 2 diabetes, yet the specific impact of structured weight-loss programmes on HbA1c within primary care remains unclear. Understanding their effectiveness is essential to inform evidence-based prevention strategies in general practice.To synthesise current evidence on the effectiveness of structured weight-loss programmes delivered or initiated in primary care on HbA1c reduction in adults with prediabetes, and to identify features associated with greater clinical benefit.A systematic review was conducted using PRISMA 2020 and SWiM guidelines. Six databases (MEDLINE, EMBASE, CENTRAL, Scopus, CINAHL, Web of Science) were searched to July 2025. Eligible studies included adults (≥18 years) with prediabetes enrolled in structured weight-loss programmes implemented in primary care. Randomised controlled trials, cohort studies, and pilot interventions were included. The primary outcome was change in HbA1c. Risk of bias was assessed using RoB-2 and ROBINS-I. Heterogeneity precluded meta-analysis; findings were synthesised narratively.Seven studies (sample sizes 43–2227) from diverse high-income settings met inclusion criteria. All interventions were associated with HbA1c reductions ranging from −0.03% to −0.83%. High-intensity behavioural programmes and digital interventions demonstrated the largest improvements. Weight loss (up to 7.2 kg), reductions in BMI, and favourable changes in lipid profiles were commonly reported secondary outcomes. Adherence consistently mediated HbA1c outcomes, with completers achieving greater benefit. However, reporting of adherence, intervention fidelity, and long-term follow-up was inconsistent across studies.Structured weight-loss programmes in primary care consistently support glycaemic improvement in prediabetes. Digital delivery models and higher-intensity behavioural programmes may enhance accessibility and impact, though variations in programme structure, population characteristics, and engagement complicate comparisons. The evidence base remains limited by heterogeneity, modest sample sizes in some studies, and lack of diverse or underserved populations.Structured weight-loss interventions delivered in primary care contribute to modest but clinically meaningful reductions in HbA1c. Integrated digital or higher-intensity behavioural approaches hold particular promise. Future research should prioritise standardised reporting, equity-focused design, and long-term outcomes to guide scalable prediabetes management in general practice.

Overweight and obesity increase morbidity and mortality. In 2022, 43% of adults worldwide were overweight. In the XXXX region, this prevalence is on the rise.  The causes of overweight are multifactorial, with significant psychosocial determinants, and there is a need for a comprehensive public prevention policy.  The Haute Autorité de Santé (HAS) identifies general practitioners as the first point of contact in the management of excess weight.Study the approach to socio-economic and psychological determinants in the management of adult overweight by general practitioners practising in the region XXXX.A quantitative descriptive and analytical cross-sectional study was conducted among private general practitioners in the XXX region, using an anonymous questionnaire emailed in October 2024. The main criterion was the approach to all the psychosocial criteria proposed according to the literature. The variables were analysed descriptively, and comparisons were then made between groups offering consultations dedicated to overweight and those that did not.195 responses were analysed. Only 12.3% of doctors addressed all psychosocial determinants ‘often’ or ‘always’. This rate reached 21.5% among doctors conducting dedicated consultations, suggesting that care remained partial despite the specific time allocated. Participants were aware of the importance of psychosocial factors in overweight, but remained focused mainly on health and dietary rules.The study reveals that the approach to overweight remains predominantly biomedical despite a declared awareness of the importance of psychosocial determinants. These determinants are addressed more frequently when doctors have specific consultations on overweight. These results highlight the value of adapting medical practices by promoting a motivational, multidisciplinary and collaborative approach. A better understanding of negative perceptions and barriers to a comprehensive approach to overweight is needed to improve the quality of care and promote more comprehensive management tailored to patients' needs.Despite awareness of the importance of psychosocial factors, doctors report an approach that is primarily biomedical and focused on health and dietary rules. Having a dedicated consultation improves overall care. A motivational, multidisciplinary approach and an ambitious public prevention policy are desirable, as the issues surrounding overweight cannot be reduced to the prism of health.
