Prevention by Design: A Declaration on Self-Care & Lifestyle Medicine
Health systems across the world are facing unprecedented pressures. Populations are ageing, the prevalence of long-term conditions continues to rise, healthcare workforces are under increasing strain, and the costs of treating preventable illness continue to escalate. Despite decades of evidence demonstrating that many chronic diseases are preventable, healthcare systems remain largely organised around treating illness rather than preventing it. This imbalance is no longer sustainable.
The Self-Care Academic Research Unit (SCARU) and the International Self-Care Foundation (ISF) believe the next evolution of healthcare must place prevention where it belongs: at the centre of health systems. That belief has led to the development of the Declaration on Self-Care and Lifestyle Medicine, a consensus framework that sets out how health systems can better integrate prevention, behavioural healthcare and person-centred care. The Declaration, together with the accompanying scholarly paper, is scheduled for publication in the Self-Care Journal in Autumn 2026.
Why another declaration?
Self-care and lifestyle medicine are often discussed together because they share a common goal: helping people live healthier lives. Yet they have largely evolved independently. Self-care focuses on empowering individuals, families and communities to maintain health, prevent disease and manage illness. Lifestyle medicine provides healthcare professionals with evidence-based approaches to address the behavioural risk factors that drive many chronic diseases.
Both fields have generated substantial evidence. However, translating that evidence into routine healthcare has remained difficult. The problem therefore is not a lack of scientific evidence, but lack of implementation. Further to the Declaration on Self-Care & Medical Leadership, another declaration that emphasises the role of self-care and the self-carer in lifestyle medicine is needed.
Understanding the implementation gap
Our work suggests that implementation depends upon three interconnected components. First, individuals need the capability to engage in self-care. This includes health literacy, confidence, skills and motivation. Second, health and care professionals need the capability and confidence to deliver evidence-based lifestyle interventions consistently during routine care. Third, health systems themselves must be designed to support prevention through commissioning, policy, workforce development and organisational infrastructure.
If any one of these components is weak, implementation becomes fragmented. Improving patient knowledge alone is unlikely to transform outcomes if clinicians lack training. Likewise, well-trained professionals cannot consistently deliver preventive care without supportive health systems. The declaration therefore argues that successful prevention depends upon simultaneously strengthening all three domains.
Introducing the Integrated Capability–Delivery–System Model
At the centre of the declaration is a new conceptual framework: the Integrated Capability–Delivery–System Model. The model proposes that effective prevention emerges from the interaction of three mutually reinforcing elements: (i) Self-care capability, (ii) Lifestyle medicine delivery, and (iii) Health system readiness.
Rather than viewing prevention as a collection of isolated interventions, the model conceptualises prevention as an integrated system. This systems perspective provides a practical way of understanding why so many well-intentioned prevention programmes struggle to achieve population-level impact despite strong supporting evidence.
Eight principles for implementation
The declaration proposes eight consensus principles to guide policymakers, healthcare organisations, clinicians and researcher: (i) Institutional legitimacy, (ii) Conceptual clarity, (iii) Workforce capability, (iv) System readiness, (v) Integrated care across the life course, (vi) Trust and professional governance, (vii) Measurement and evaluation, and (viii) Equity and access. Together, these principles move beyond simply encouraging healthier lifestyles. They describe the conditions required for prevention to become embedded within routine healthcare.
Why this matters now
Across health and care, there is growing recognition that preventing disease is both clinically effective and economically necessary. However, prevention cannot rely solely upon individual motivation. People require support whereas health and care professionals require training. Meanwhile, organisations require infrastructure and health systems require incentives that reward prevention rather than simply responding to disease once it has developed. This declaration argues that prevention should no longer be viewed as an optional addition to healthcare. It should be recognised as one of its defining functions.
Looking ahead
The Declaration on Self-Care and Lifestyle Medicine is intended as a starting point rather than an endpoint. It provides a shared framework that researchers, clinicians, commissioners, policymakers and patient organisations can use to align future work. Future research will continue to test, refine and operationalise the framework across different health systems and populations. As healthcare increasingly shifts towards prevention, integrated care and personalised medicine, developing coherent implementation frameworks will become just as important as generating new evidence. The challenge is no longer proving that prevention works but ensuring health systems are designed to deliver it.
The declaration is intended to catalyse new collaborations across academia, healthcare and policy. By promoting multidisciplinary research, producing high-quality scholarly outputs and strengthening international partnerships, we aim to advance the evidence base for self-care and lifestyle medicine, accelerate their integration into routine health and care, and ultimately improve population health outcomes at scale.
