  • 1. Neighborhood Design & Obesity
  • 2. What is BMI?
    Body Mass Index (BMI)
    Weight in kilograms divided by the square of height in meters
    <18.5 underweight
    18.5-24.9 normal weight
    25-29.9 overweight
    ≥ 30 obese

    Where do people buy their food?
    Where do people exercise?
    How do people go from home to work?
  • 9. Neighborhood Design Issues
    • Low Density (1 unit/acre), low connectivity streets
    Higher density (12 units/acres), higher connectivity streets
  • 10. Street Connectivity
    .5 mile vs. 1.3 miles to walk the same straight distance
  • 11. Where would you rather walk?
  • 12. Diverse Destinations
  • 13. Population Density
  • 14. Reviewing…
    Rising overweight/obesity in the U.S. is a major health problem
    Communities may play a critical role in altering the risk of being overweight/obese via
    Choices about physical infrastructure (bike lanes)
    Choices about retail food (zoning, tax incentives)
    Choices about public transportation
    Focus of research on the “3D’s”
    Community Design
    Land Use Diversity
    Population Density
