Decoding the WHO Healthy Ageing Framework
The World Health Organization's (WHO) healthy aging framework is a comprehensive approach that moves beyond simply the absence of disease. It focuses on functional ability, which is the capability to do and be what an individual values. This is determined by the interaction between a person’s intrinsic capacity and the environment they live in. A deeper understanding of this framework is crucial for anyone involved in senior care, public health, or personal wellness planning for later life.
The 5 Domains of Functional Ability
The cornerstone of the WHO's healthy aging concept is the five domains of functional ability. These abilities are interdependent and contribute collectively to an individual's wellbeing. By focusing on maintaining and optimizing these areas, older adults can sustain their independence and quality of life.
1. Meeting Basic Needs
This domain refers to the ability to perform fundamental daily tasks necessary for survival and comfort. It includes aspects such as:
- Maintaining proper hygiene and personal care
- Managing nutrition and hydration
- Ensuring financial security to cover essentials like housing and food
- Having access to safe and appropriate living conditions
- Receiving sufficient healthcare services for common ailments
2. Learning, Growing, and Making Decisions
Staying engaged mentally is vital for healthy aging. This domain encompasses the cognitive abilities that allow an individual to continue developing and participating in life. It includes:
- Engaging in lifelong learning, from formal education to new hobbies
- Exercising critical thinking and problem-solving skills
- Being able to understand and make informed decisions about one's health and finances
- Maintaining cognitive function through stimulation and mental exercises
3. Being Mobile
Mobility is a key determinant of independence and is often a focus of care plans for older adults. The ability to move and get around freely impacts social engagement and daily activities. This domain includes:
- Physical capabilities like walking, balance, and coordination
- Accessing transportation, whether public or private
- Using assistive devices, if needed, to maintain independence
- Performing routine exercises to maintain strength and flexibility
4. Building and Maintaining Relationships
Social connection is a powerful determinant of health. This domain highlights the importance of social integration and support networks for emotional and psychological wellbeing. It involves:
- Engaging with family, friends, and neighbors
- Participating in community activities and social gatherings
- Combating social isolation and loneliness
- Leveraging technology to stay connected with loved ones from a distance
5. Contributing to Society
Feeling useful and valued is crucial for a positive aging experience. This domain focuses on the ability of older adults to continue making meaningful contributions to their communities and families. It can be achieved through:
- Volunteering for a cause they care about
- Continuing to work, either full-time or part-time
- Sharing knowledge and skills with younger generations
- Taking on caregiving roles for family members
The Core Components: Intrinsic Capacity and Environment
Beyond the five domains, the WHO framework identifies two interconnected core components: intrinsic capacity and environment. These elements constantly interact to shape an individual’s functional ability over their lifetime. A decline in one can impact the others, and interventions in one area can positively affect the whole system.
Intrinsic Capacity: This refers to the physical and mental capacities a person possesses. It includes everything from mental health and cognitive function to physical strength, sensory perception, and resilience. Intrinsic capacity is influenced by factors such as age-related changes, diseases, and injuries.
Environment: This includes all external factors that can impact an individual's functional ability. This covers the home, community, and societal levels, including:
- The built environment (transportation, housing, public spaces)
- Social relationships and support networks
- Policies and health systems that enable or hinder healthy living
- Attitudes and values related to aging (combating ageism)
Comparison of Active Ageing vs. Healthy Ageing
While the concept of "active ageing" was a focus of the WHO's work in the early 2000s, the updated "healthy ageing" framework provides a more comprehensive perspective.
| Feature | Active Ageing | Healthy Ageing |
|---|---|---|
| Focus | Optimizing health, participation, and security to enhance quality of life in older age. | Maintaining functional ability to enable overall wellbeing throughout older age. |
| Scope | Emphasized physical activity and social participation, but was seen as less inclusive of those with diminished health. | More holistic, focusing on enabling wellbeing for all older adults, regardless of health status, including those with one or more conditions. |
| Framework | Built on four pillars: health, lifelong learning, participation, and security. | Built on three core components: intrinsic capacity, environment, and functional ability. |
| Evolution | A precursor to the current framework, now replaced by the broader concept. | The current WHO framework, established for the Decade of Healthy Ageing (2021–2030). |
Promoting Healthy Aging at Every Level
The WHO's vision is a world where everyone can live a long and healthy life. Achieving this requires action at all levels, from individuals and communities to national policies. By focusing on optimizing functional ability and addressing environmental barriers, society can better support its aging population.

Conclusion
The WHO's definition and domains for healthy aging offer a crucial roadmap for rethinking how we approach the later years of life. Instead of viewing aging solely as a process of decline, the framework highlights the potential for ongoing growth, contribution, and wellbeing. By focusing on functional ability across the five key domains—meeting basic needs, learning, mobility, relationships, and societal contribution—we can create environments that support older adults in being and doing what they value most. This holistic perspective is essential for ensuring that as global populations age, they do so in a healthy, dignified, and engaged manner.
