A holistic view of healthy ageing
Contemporary research aligns with the World Health Organization's (WHO) broad definition of health, which includes physical, mental/cognitive, and social well-being, moving beyond simply being free from disease. Healthy ageing is viewed as a dynamic process influenced by numerous interconnected factors that evolve throughout a person's life, shaped by personal choices, environment, and social context. Identifying these determinants is key to developing effective strategies for promoting well-being in later life.
The core determinants of healthy ageing
A systematic review of contemporary literature published between 2010 and 2020 identified ten consistent and significant determinants of healthy ageing. These determinants span multiple domains, reinforcing that well-being is multifaceted. Independence was particularly notable as it influences physical, mental, and social aspects of healthy ageing.
Physical well-being determinants
Maintaining physical function is essential for healthy ageing. Two key determinants in this area are:
- Physical Activity: Regular exercise supports cardiovascular health, builds muscle, and improves flexibility, reducing the risk of chronic diseases and delaying dependency.
- Diet: A healthy diet boosts immunity and provides essential nutrients. Diets like the Mediterranean or DASH diets, rich in fruits, vegetables, and whole grains, are associated with significant health benefits.
Mental and cognitive well-being determinants
Mental and cognitive factors were highlighted in all studies reviewed. Four important determinants for mental sharpness and emotional resilience include:
- Self-Awareness: This involves self-esteem, resilience, body awareness, and a sense of purpose, providing psychological strength in older age.
- Outlook/Attitude: A positive perspective on the future is linked to greater life satisfaction and better psychological well-being.
- Life-long Learning: Engaging in activities that challenge the mind helps maintain cognitive function.
- Faith: For many, spirituality offers stability and purpose, supporting psychological well-being, especially during difficult times.
Social well-being determinants
Social connections significantly impact healthy ageing. The review identified three key social determinants:
- Social Support: Strong relationships with family and friends help combat isolation and loneliness, which are linked to negative health outcomes.
- Financial Security: The ability to afford necessary care and maintain a good quality of life reduces stress and contributes to overall well-being.
- Community Engagement: Participating in community activities offers a sense of belonging and enhances social interaction.
The influential role of environment
Both social and built environments have a lasting impact on how individuals age. Key environmental factors include:
- Neighborhood Safety and Accessibility: Safe and accessible neighborhoods encourage physical activity and social interaction.
- Access to Healthcare and Quality Care: Regular preventative care and access to managing chronic conditions are vital for health outcomes.
- Housing Stability and Quality: Secure and adequate housing is fundamental for health, particularly for those with chronic conditions.
- Social and Community Context: Strong social networks within a community provide support and positively influence health.
Modifiable vs. non-modifiable determinants
While some factors are unchangeable, many determinants of healthy ageing can be actively managed for better health outcomes.
| Determinant Type | Modifiable Examples | Non-Modifiable Examples |
|---|---|---|
| Physical Health | Diet, exercise, sleep hygiene | Genetics, age |
| Mental/Cognitive Health | Learning, stress management, social engagement | Genetic predispositions |
| Social & Financial Health | Social support, community involvement, savings | Family history, historical policies |
| Environmental Factors | Accessing health services, improving housing | Geographic location, inherited circumstances |
Conclusion: a pathway to healthier, longer lives
This systematic review underscores that healthy ageing is a complex interaction of physical, mental, and social factors. It highlights the importance of lifestyle choices like diet and exercise, alongside psychological resilience, a positive outlook, and strong social connections. Crucially, many of these influential factors are modifiable, offering a proactive approach to ageing rather than a passive one. Focusing on these determinants can lead to more effective strategies for maintaining well-being, independence, and quality of life in later years.

Methodological considerations
The review focused on contemporary evidence from 2010 to 2020, identifying ten common determinants within healthy ageing frameworks. The increasing recognition of mental/cognitive and social well-being marks an evolution in research. However, the review also suggests that the precise contribution of each determinant requires further investigation and standardization for better cross-cultural comparisons.
The takeaway
Healthy ageing is an active, life-long process influenced by a mix of physical, mental, and social determinants. While some factors are fixed, many can be positively influenced through lifestyle, community involvement, and psychological resilience. This contemporary review offers a solid foundation for both individual actions and public health policies aimed at promoting healthier and more fulfilling later lives.
