It is becoming too easy to be less physically active!
Even walking the dog does not guarantee physical activity anymore!
Physical activity is being engineered out of our daily lives in many ways
Population-based problems require population-based answers
Creating built environments that are supportive of physical activity is one strategy for increasing physical activity participation at the population level
Why is the built environment important for promoting physical activity at a population level?
Creating supportive built environments has the potential to influence the behaviour of entire communities and populations and not just individuals
Why is the built environment important for promoting physical activity at a population level?
Creating supportive built environments has the potential to influence behaviour over a long time (e.g. many generations) because of its semi-permanency
Why is the built environment important for promoting physical activity at a population level?
Creating supportive built environments can encourage people to be active without them even thinking about it
Major attributes that contribute to a supportive environment for physical activity1,2Land use mix and destinations close to homeRecreational and utilitarian
ConnectivityStreet patterns that make pedestrian movement convenient but motor vehicle movement less convenient
Appeal and aestheticsTrees, architecture, interesting, separation of pedestrians and motor vehicles
Safe placesPersonal safety, traffic safety, evidence of order (i.e. no graffiti or vandalism)
Residential densitySee other people active, surveillance, economically viable for small business

The EcoEUFORIA project
Definition
Economic Evaluation of Using Urban Form to Increase Activity
Overall objective
To examine the cost effectiveness of creating pedestrian-friendly neighbourhoods as a an intervention for increasing physical activity and improving health
Project context
Calgary metropolitan area
The EcoEUFORIA projectMethods (sampling)
Two random samples (n = 2200 each wave)
Wave 1: conducted in Summer/Early fall (August to October, 2007)Wave 2: conducted in Winter/Early spring (January to April, 2008)
Telephone-interview with a follow-up postal surveyInterviews conducted by CHR
Households sampled from directory of listed telephone numbers
One person per household >18 years
The EcoEUFORIA projectMethods (telephone-interviews)
Neighbourhood-specific physical activity behaviour1,2Inside versus outside the neighbourhoodNeighbourhood defined as a 15-minute walk from home
Walking for transportation; walking for recreation; vigorous-intensity physical activity; and moderate-intensity physical activity
Frequency and duration during a usual week
1McCormack, Shiell, Doyle-Baker, Friedenreich, Sandalack, & Giles-Corti (in press). Testing the reliability of neighborhood-specific measures of physical activity among Canadian adults. Journal of Physical Activity and Health2Giles-Corti et al. (2006) Development of a reliable measure of walking within and outside the local neighborhood: RESIDE's Neighborhood Physical Activity Questionnaire. Preventive Medicine
The EcoEUFORIA projectReasons for residential-selection1
Importance of certain neighbourhood characteristics associated with physical activityAffordability, aesthetics, attractive scenery and cleanlinessProximity to: public transport; parks; shops; services; work; recreation; and trailsEase of walking and drivingAccess to places to be physically active
Neighbourhood self-selection
A major limitation of previous research
Psychological variables (TBP) and demographics
Cerin et al (2007). Destinations that matter: Associations with walking for transport. Health and Place
The EcoEUFORIA projectMethods (postal-survey)Included those completing the telephone-survey and agreeing to follow-upTwo follow-up letters sent and incentive for returned surveys
Captured data:Perceptions of neighbourhood walkability (ANEWS)1Social support (dog ownership, club membership, friends and family)Social capital and sense of communitySelf-rated health and height and weightMotor vehicle access and driving behaviourDemographics

The EcoEUFORIA projectResults to date (wave 1 completed)
N = 2200 telephone-interviews completed (RR 34%)
N = 1813 agreed to postal-survey (RR 82%)
N = 1055 returned completed postal-survey (RR 58%)
Respondents returning the postal-survey are similar on most demographic attributes to those completing the telephone-interview but not agreeing to postal survey
Results
Perceptions of neighbourhood walkability assessed using the Abbreviated Neighbourhood Walkability Scale (ANEWS)
Perceptions of neighbourhood walkability (ANEWS subscales)
*Count of destinations located within 15-minute walk of home; N=1055; Higher scores indicate higher perceived walkability
Results
Where does walking take place in relation to neighbourhoods and how is it associated with walkability?
Where does physical activity take place (participation)?
Prevalence of walking for transport inside the neighbourhood by neighbourhood walkability
*p
Prevalence of walking for recreation inside the neighbourhood by neighbourhood walkability
*p
Where does physical activity take place (minutes)?
(210 minutes/wk = 30 minutes/day or 420 minutes/wk = 60 minutes/day guideline)
Spearmans Rank correlations between perceptions of neighbourhood walkability (ANEWS subscales) and walking inside the neighbourhood
*p
Prevalence of walking inside the neighbourhood by perceived overall walkability
*p
Minutes of walking inside the neighbourhood by perceived overall walkability
*p
ConclusionsMost walking behaviour is undertaken close to home
Different attributes of the built environment are associated with specific types of walking (i.e. for transport versus recreation)
Preliminary analysis adjusting for demographics (age, gender, education, No. children
