Exploring the relationship between human behaviours and outcomes

Who we are

We’re a research unit dedicated to developing the science of behaviour change. To do this, we aim to better understand how our behaviours can affect outcomes like our health, life expectancy and productivity.

We work with a range of respected academic institutions and research partners to develop research that has real-world applications for businesses, individuals and society. This also ensures that what we do is consistent with our Shared Value business model.

Our Latest Research

Maximising the number of years lived in good health

While life expectancy has increased dramatically over the last century, people are not living all of those extra years in good health. The first of our research papers aims to address this growing gap between length and quality of life. It highlights the changes that people can make to support their health, as well as their retirement.

Looking beyond life expectancy

Lifespan [or life expectancy]

The number of years a person lives.

Healthspan [or healthy life expectancy]
The number of years a person can expect to live in good health.
Healthspan gap
The difference between a person's lifespan and their healthspan due to factors like disease, injury and frailty. 

The widening healthspan gap in the UK

The good news is that better healthcare treatment and technologies have led to longer lifespans in the UK.

However, while life expectancy has grown by over five years since 1990, healthy life expectancy has grown at a slower rate. Partly due to lifestyle choices, this has led to a widening healthspan gap and lower quality of life. Currently around 7.3 million healthy years of life are lost in the UK every year.

The implications of a widening healthspan gap

The effects of a widening healthspan gap can be seen elsewhere too. UK workforces are experiencing productivity loss, causing businesses to lose up to £39 billion per year. This is down to the poor lifestyle choices and mental health issues of employees. Furthermore, largely preventable chronic conditions, such as heart disease and diabetes, are becoming more common. This means the healthcare system is facing mounting costs as well.

Therefore, the economic pay-off of reducing the healthspan gap is considerable. What's more, reversing the causes of the widening healthspan gap will allow the benefits to be sustained long into the future.

Prevention and behaviour change are the solution

So, what can be done?

To encourage healthy lifestyle behaviours and reduce metabolic risks, we need well-structured health strategies that combine treatment with prevention. These should be a coalition of individual, corporate and governmental action. The positive consequences will benefit everyone and have knock-on effects for the economy.

Our report highlights physical activity and a healthy diet as key actions. To examine our reasons, as well as our proposed action points, read the full report.

"While life expectancy provides a measure of a society’s progress, it is our health span, the number of years we can expect to live in good health, that should demand our attention with a focus on quality of life."
