Naturally Better – Howbery Park, Wallingford – 26th March 2009 Green space, physical activity and public health Dr. Charlie Foster – Senior Researcher BHF Health Promotion Research Group University of Oxford Presentation Objectives To briefly describe the relationship between green space, public health and physical activity Describe the evidence base for this relationship Offer possible directions for developing this evidence base Presentation Objectives To briefly describe the relationship between green space, public health and physical activity Describe the evidence base for this relationship Offer possible directions for developing this evidence base 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) Presentation Objectives To briefly describe the relationship between green space, public health and physical activity Describe the evidence base for this relationship Offer possible directions for developing this evidence base Mitchell and Popham (2008) Access to green space is associated with better health for the poorer half of the population Incidence rate ratios for deaths from circulatory disease in income deprivation quartiles 2–4, relative to income deprivation quartile 1 (least deprived), stratified by exposure to green space Mitchell and Popham.

Perceptions Safety Quality of public space Objective Places to go locally Deprivation Poverty 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) 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) Parks are places for all to play (Moore, 2003) Source: news.yahoo.com Friday 7 January 2005 Men’s Fitness Criteria Outcome Overweight & obesity rates Exposure junk food outlets gyms/sporting goods retailers fruit and vegetable consumption participation in exercise/sports alcohol use smoking TV viewing air quality water quality climate index geography commute time parks/open spaces recreation facilities health care access 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! Presentation Objectives To briefly describe the relationship between green space, public health and physical activity 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?
