Consensus on health benefits of green space
 Green
space can reduce the risk of:
» Promotes good health and prevents ill health
– Stress
– Anxiety
– Depression
» A place for physical activity
(Bedimo-Rung et al, 2005; Hartig, 2007; Moore & Cosco, 2007; Ottoson, 2007)
Public health importance of physical activity in the UK




Adults who are physically active have a 20-30%
reduced mortality risk compared to inactive adults.
Estimates put the total direct costs to England of
physical inactivity to the NHS as £1.06 billion
Conservatively, this represents about 54,000 lives
lost prematurely per annum.
A 10% increase in adult activity would benefit
England by at least £500m a year (saving about
6,000 lives).
(Game Plan, Strategy Unit 2002; Allender et al, 2006)
Cost of physical inactivity related disease in London

The cost of illness for physical activity related
disease is nearly £14 per Londoner

The PCT spend on physical activity promotion
is 85p per Londoner
(Foster et al, 2009)

Green spaces, environmental
correlates and physical activity
Proximity to recreation facilities, convenience
Destination factors, micro-scale design, footpaths, trails
Mixed land use, shops and services nearby
Aesthetics (perceived)
Population density/sprawl
Area based Coastal residence
Area based Urban/age of suburb
Culture, social environment as most important
Connectivity
Walkability
Route related factors, hills, traffic
Perceived safety
High crime rate
Unattended dogs

The contribution of
environmental variables in
explaining variation of physical
activity or walking is
small and less important than
sociodemographic variables.

Using green space to promote
physical activity – NICE evidence
Only found 2 grey studies
 WHY?

» Different views on what is evidence?

But some evidence does exist…..
Using green space to promote physical
activity via play– NICE evidence

Real v perceived risk
Using green space to promote physical
activity via play– NICE evidence
Real v perceived risk
 Parks mean independence leading to
more physical activity (Mackett, 2007)

Inverse Leisure Law Study


Leisure-time physical
activity patterns are low
and socially patterned
Is there a relationship
between
neighbourhood
deprivation and the
density of physical
activity facilities in
England?
Inverse Leisure Law Study - Method
A database of all indoor exercise
facilities in England was obtained, and
facilities were linked to administrative
areas and assigned a deprivation score
 Census data were used to calculate the
density of physical activity facilities per
1000 people per quintile of deprivation

The density of exercise facilities by quintile of
deprivation for the county of Kent in Southeast England
The density of access to green space by quintile of
deprivation for the county of Kent in Southeast England
Let’s look at green space access now!

Describe the evidence base for this
relationship
Offer possible directions for developing
this evidence base
Other missing evidence…?

Does access and actual use of green
space relate to health status
» Related to quality or characteristics of
green space?
» Change in one lead to improvements?

The economic value of green space
» Contribution to economy, health costs and
Quality of life
Green space, public health and physical
activity - Conclusions
Green space is related to health
 Physical activity is related to health
 Our environment and how we use it does
impact on our health
