Two people can be born in the same year. One moves through their fifties with strength, resilience and barely a twinge. The other is already managing chronic back pain, stiffness and a body that seems to be ageing faster than the calendar suggests.
One factor researchers are increasingly exploring is biological age.
Chronological Age vs. Biological Age
Chronological age is simple: it’s the number of years since you were born. It moves in one direction, at exactly the same pace, for everyone.
What Research Says About Biological Age and Chronic Pain
Scientists can estimate aspects of biological ageing using tools called epigenetic clocks. These analyse patterns of DNA methylation, chemical changes associated with ageing and other biological processes, to estimate how a person’s biological ageing compares with their chronological age.
A growing body of research has explored how these markers relate to chronic pain:
- Older adults with chronic pain have shown differences in epigenetic age compared with pain-free adults of a similar chronological age, with some studies also finding associations with aspects of physical or cognitive function.
- In people with chronic low back pain, a measure called the pace of biological ageing, which looks at how quickly ageing-related biological changes are occurring, has been associated with pain severity and how much pain interferes with daily life.
- Larger studies have also found associations between high-impact chronic pain and accelerated ageing across several epigenetic measures.
- Research examining physical function has found links between biological ageing markers, pain-related limitations and measures such as grip strength.
Together, these findings suggest there may be a relationship between chronic pain and biological ageing. However, this is still a developing field, and researchers haven’t established a simple cause-and-effect relationship.
Why the Connection Isn’t a One-Way Street
It’s tempting to interpret this research as “ageing faster causes pain”, but the scientific picture is more layered. Several explanations are being investigated.
Faster biological ageing may be associated with changes in inflammation, tissue function and pain sensitivity. At the same time, living with persistent pain can affect sleep, stress levels, activity and other lifestyle factors that are themselves associated with ageing-related biological changes.
Common factors may also influence both. Poor sleep, ongoing stress, lower levels of physical activity and inflammation have all been studied in relation to chronic pain and biological ageing.
Researchers therefore describe these findings as associations rather than proof that one directly causes the other. That distinction matters, particularly when deciding what the research means for someone living with persistent pain.
Looking Beyond Wear and Tear
For many years, musculoskeletal pain was often explained mainly in mechanical terms, such as worn joints, disc changes or accumulated “wear and tear”. Research into biological ageing adds another possible piece to the picture.
If biological ageing is associated with pain severity and physical function, chronological age alone may not tell us much about how someone will feel or move. Even two people with similar findings on an X-ray or scan may experience their symptoms very differently.
That’s one reason assessment shouldn’t focus only on an image or a person’s age. Movement, strength, daily activities, sleep, stress and other health factors can all provide useful context when looking at a musculoskeletal concern.
For people in West Perth dealing with ongoing back, neck or joint discomfort, this broader view may help explain why care needs to be considered on an individual basis.
Lifestyle Factors Linked with Healthier Ageing
Unlike chronological age, some biological ageing markers appear to be influenced by modifiable health and lifestyle factors. Research continues to explore the role of:
- Regular, appropriate movement: Staying physically active and maintaining mobility are associated with better health across the lifespan. Activity should be appropriate for the individual, particularly when pain or injury is present.
- Quality sleep: Sleep affects many processes involved in physical and mental health, including recovery and stress regulation.
- Managing ongoing stress: Long-term stress has been associated with inflammatory and biological ageing markers.
- Nutrition and general health habits: Dietary patterns and other lifestyle factors may influence inflammation and several markers associated with ageing.
- Maintaining strength and physical capacity: Strength, mobility and the ability to stay active are valuable measures of physical function as we age.
These factors shouldn’t be interpreted to mean that lifestyle choices simply cause chronic pain. Injuries, health conditions, structural changes and many other factors can play a role.
Instead, the research highlights why looking beyond the painful area itself may provide a more complete picture of a person’s health and physical function.
What Biological Age Research May Mean for Chronic Pain
Chronic pain and biological ageing appear to be linked, although researchers are still working out why and what that relationship means over the long term. People of the same chronological age can show very different biological ageing patterns, which may be one of many reasons pain and physical function differ so much from person to person.
What this research also suggests is that age alone doesn’t define how someone will move or feel. Regular activity, sleep, stress management, strength and other everyday health behaviours may all play a role in maintaining physical function as the years pass.
