Why does obesity matter? Obesity and Disease Risk: Obesity = Diabetes High Blood Pressure Heart Disease Stroke Arthritis Asthma Some cancers
Modifiable Behaviors Associated with Deaths, US, 1990 Three hundred thousand!
How much physical activity do we need each day to stay healthy? • 30 minutes physical activity (cumulative) • moderate level/most days • Result: significant health benefits Surgeon General’s Recommendation
Who says community design matters? The Centers for Disease Control “Changes in the community environment to promote physical activity may offer the most practical approach to prevent obesity or reduce its co-morbidities. Restoration of physical activity as part of the daily routine represents a critical goal.” Dr. Jeffrey Koplan, Dr. William Dietz, CDC
Why Walking and Bicycling? “Automobile trips that can be safely replaced by walking or bicycling offer the first target for increased physical activity in communities.” Dr. Jeffrey Koplan, Dr. William Dietz, CDC
What about children going to school? • Only 31% of trips under 1 mile are by walking • Only 2% of trips under 2 miles are by bicycling
What is needed for healthy change? Changes in individual behavior Proactive encouragement by health care providers Community designs that make walking & biking safe, easy & enjoyable!
How do we create Active Community Environments? Street designs that improve pedestrian & bicycle convenience, comfort & safety Development patterns that improve the walking & biking environment
Or? Which design encourages more activity? Community design patterns matter

Development patterns can improve the walking & bicycling environment • Mix of land uses • Site design • Interconnected streets • Human-scale design
Mixed land use: schools, shops, parks close by To which store are you more likely to walk?
Site design: getting to buildings on foot or by bike How do you get there from here?
