Understanding the Concept of Healthy Ageing
The World Health Organization (WHO) defines healthy ageing as the process of developing and maintaining the functional ability that enables well-being in older age. Functional ability is the core of this framework and involves a person’s capabilities to perform valued tasks and activities. It is a product of the interaction between an individual's intrinsic capacity and their environment. This holistic approach shifts the focus from simply being free of disease to enabling older people to be and do what they have reason to value, such as meeting basic needs, learning, making decisions, building relationships, and contributing to society.
Intrinsic capacity includes all mental and physical capabilities, encompassing physical capacity (mobility, strength), cognitive function, and mental health. The environment includes the home, community, and broader social and physical contexts. The interplay between these two components determines an older person’s functional ability. A person with declining intrinsic capacity may maintain functional ability if they live in a supportive, accessible environment.
The World Health Organization's Initiatives
In response to the global demographic shift, the WHO launched the Decade of Healthy Ageing (2020–2030) to continue its work on ageing and health. This initiative provides a strategic framework built on five interconnected areas of action:
- Aligning health systems to the needs of older people: Shifting from disease-focused acute care to person-centered integrated care that maintains functional ability.
- Creating age-friendly environments: Making cities and communities more inclusive, safe, and accessible for older people, encompassing everything from transportation to housing.
- Combating ageism: Running global campaigns to change attitudes and combat stereotypes and discrimination based on age.
- Laying the foundations for long-term care: Building sustainable and equitable systems for long-term care that prioritize the needs of older people.
- Improving measurement, monitoring, and research: Enhancing data collection and research to better understand healthy ageing and evaluate progress.
The 4Ms Framework for Clinical Care
While the WHO provides a broad strategic framework, specific models guide clinical practice. The Institute for Healthcare Improvement (IHI) and The John A. Hartford Foundation promote the Age-Friendly Health Systems initiative, which utilizes the 4Ms framework for direct patient care. The 4Ms are:
- What Matters: Focusing on the older person's health goals, care preferences, and priorities. This ensures that treatment aligns with what is most important to the individual.
- Medication: Managing medications to reduce polypharmacy and ensure the use of age-friendly medications that do not compromise the older person's health.
- Mentation (Mind): Assessing and managing common mental health conditions, such as dementia, delirium, and depression, to promote cognitive and psychological well-being.
- Mobility: Encouraging older people to move safely every day to maintain function and prevent mobility decline.
The Role of Social Determinants of Health
Public health bodies, including the Centers for Disease Control and Prevention (CDC) and Healthy People 2030, recognize the profound impact of Social Determinants of Health (SDOH) on an older person's well-being. These are the conditions in which people live, work, and age. Addressing these factors is central to implementing any framework for older people. The five key SDOH domains are:
- Economic Stability: Access to resources and financial security for basic needs like housing, food, and healthcare.
- Social and Community Context: The influence of relationships, social engagement, and community support on mental and physical health.
- Education Access and Quality: Promoting health literacy and lifelong learning to empower older adults to make informed decisions.
- Healthcare Access and Quality: Ensuring affordable, accessible, and high-quality healthcare services, especially for chronic conditions.
- Neighborhood and Built Environment: The safety and accessibility of the physical environment, including housing, transportation, and green spaces, to support independence.
A Comparison of Leading Frameworks
While overlapping, the main frameworks for older people serve different but complementary functions, as highlighted in the following comparison:
| Feature | WHO Healthy Ageing Framework | Age-Friendly 4Ms Framework | Social Determinants of Health (SDOH) |
|---|---|---|---|
| Scope | Broad, global public health strategy. | Clinical and healthcare system practice focus. | Environmental and societal factors influencing health. |
| Primary Goal | Maximize functional ability and well-being in older age. | Improve quality of clinical care for older adults. | Address root causes of health inequities over the lifespan. |
| Key Components | Functional ability (intrinsic capacity + environment), age-friendly environments, long-term care. | What Matters, Medication, Mentation, Mobility. | Economic stability, social context, education, healthcare access, built environment. |
| Implementation Level | National and international policy level. | Direct patient and healthcare system level. | Community, policy, and societal levels. |
| Key Stakeholders | Governments, NGOs, international bodies. | Hospitals, clinics, healthcare providers. | Public health agencies, local governments, community leaders. |
Challenges and Next Steps for a Cohesive Framework
Despite the existence of these frameworks, consistent and effective implementation remains a challenge. Issues include limited resources in lower-income countries, fragmented care systems, and pervasive ageism that devalues older adults. The COVID-19 pandemic, for example, starkly exposed and exacerbated these vulnerabilities.
Moving forward, a cohesive strategy must involve a multi-sectoral approach that integrates the different frameworks. This requires aligning macro-level policies (like the WHO Decade) with micro-level clinical practices (like the 4Ms) and addressing the underlying societal issues (SDOH). Furthermore, it demands ongoing research and data collection to monitor progress and adapt strategies to the diverse needs of older populations.
The Path to an Age-Friendly Future
Ultimately, the goal is to create societies where older people are not just seen as recipients of care, but as active participants in their communities. By adopting and integrating these frameworks, communities can build environments and systems that support the independence, dignity, and overall well-being of older adults. The transition requires a collective effort, from policymakers creating age-inclusive legislation to individuals challenging their own preconceived notions about ageing.
