• Obesity Prevention Strategy
Region of Peel: Caledon, Brampton and Mississauga
Rapid Growth – 1.5 million by 2031
Highest settlement in Brampton, Mississauga.
Unique Challenges: development of intensification in Mississauga; greenfield in Brampton; rural community in Caledon (Peel Planning/05)
• Rapid growth is fueling more vehicle trips (Peel Planning/05)
• Single occupant vehicle trips increasing
• Physical Activity levels are decreasing
• Obesity and related chronic diseases like diabetes, cardiovascular disease are increasing (Health Status Report/05)
Health and Urban Form: BackgroundHealth and Urban Form: Background
• Council discussion 2002 narrow focus – individual control
• Council Report - “State of the Region’s Health: Focus on Overweight, Obesity and Related Health Consequences in Adults” (2005)
• Recommendations– Marketing– School food activity environment– Policy-active/public transportation– Policy-built environment
Health and Urban Form: BackgroundHealth and Urban Form: Background
Council Resolution:
advocate for provincial legislation to limit advertising of unhealthy foods during
children's TV programmingPrivate Members Bill to limit children’s food ads in Ontario
work with school boards to implement programs and policies that support children to eat healthy and be activeEducation Act Amendment: Bill 8 (Healthy Food for Healthy Schools
Act)
Health and Urban Form: BackgroundHealth and Urban Form: Background
Council Resolution:
study and make recommendations for planning policies and processes that provide greater
opportunities for active living
advocate for policies which strengthen public and active transportation option
Active Transportation Initiative (Phase 1 = Social Marketing Campaign; Phase 2 = Plan)
Health staff to comment on any development applications that come to the Region for comment

Urban Form Health Assessment Tool: WHATUrban Form Health Assessment Tool: WHAT
PURPOSE
Develop an evidence-based prototype Health Assessment Tool that would systematically identify the public health impact of built environments in Peel
Goals:
1. Promote the development of healthier built environments in Peel
2. Using the tool’s statistical relationships, develop health and urban form policy
Urban Form Health Assessment Tool: WHYUrban Form Health Assessment Tool: WHY
1. Seattle Study: Lawrence Frank:
A 5% increase in Walkability is associated with:
1) A 32% increase in minutes walking and biking
2) A ¼ pt reduction in BMI (about ½ kilogram)
3) A 6.5% reduction in per capita vehicle kilometers travelled
4) A 5.5% reduction in ozone precursors
2. Atlanta Study: Lawrence Frank:
1) Additional 30 minutes driving/day 3% increase obesity likelihood
2) Additional KM walked 4.8% reduction in obesity likelihood
3) AJPM/08 study
• No behaviour difference in more walkable community
• Crime reduced walking in walkable community

DATAPLANNING VARIABLES:
• Parks and Trails
• Transit routes/schedules/stops
• Greenspace
• Sidewalk Attribution
• Census information (demographic, income, HH size)
• Postal code polygons
• Building Square Footage
• Property Assessment Parcels
• Street Networks (signalized intersections)
• Traffic Zone Data
HUMAN DATA:
• Physical Activity
• Sedentary Activity
• Leisure Activity
• Obesity
• Chronic Conditions
• Stress
• Mode of travel to work
• Public Transit Use
Urban Form Health Assessment Tool: HOWUrban Form Health Assessment Tool: HOW
Tool Requirements:
1.Ability to evaluate land development alternatives
2.Ability to evaluate at a relatively small scale (neighbourhood)
3. Flexibility to incorporate outcomes and land use measures based on reasearch
4.Ability to incorporate health and air quality outcomes
Urban Form Health Assessment Tool: THE MODEL
Potential model PLACE3S
1. Web-based
2. GIS-based – Visual Output
3. Flexible
4. Public engagement and collaborative decision making
5. Meets our model requirements for Tool
6. Used in other government settings (California, Seattle)
Obesity prevention strategy reframe obesity epidemic to comprehensive health promotion interventions:
– Built environment policy
– Food environment policy then
– Behaviour change interventions, i.e. skill building (Popkin 2005)

Food Environment - Influencing Factors: The Case for Healthy Public Policy
Biological Factors• Biological drive to eat to survive• Evolutionary perspective, obesity rates predictable• Increase access to calorically-dense food• Decreased activity (clerical 300 less calories)• Eating patterns reflect caloric needs of ancestors
Other Factors• Psychological factors, satiety• Sociological, cultural, familial factors
(Bursey, Health Status Report/08)
A Case for Healthy Public PolicyBeyond Individual control because of Changes in FoodSupply and Globalization of Food Industry
• Widespread availability of cheap food• Increase portion sizes, caloric density• Increase in food marketing
• Lack of regulation of food marketing or content of food supply in relation to prevention of chronic disease• Lack of policy, i.e. government, workplace standards for small portions, flavourful, nutritious food on site
