Lecture on Obesity and Health Disparities

Key Statistics and Facts

• Obesity in America

  • 18%+ of children are obese.
  • 2/3 of Americans are overweight or obese.
  • Obesity leads to health issues like diabetes, sleep apnea, and high blood pressure.

• Impact of Socioeconomic Factors

  • Upper East Side (highest income) has low obesity and diabetes rates.
  • Tennessee has crisis level obesity rates; 1 in 10 adults have diabetes.
  • Orange County, CA shows disparity with high park space but pockets of poverty with high obesity rates.

Urban Design and Environment

• Access to Healthy Food

  • Areas with high poverty have fewer sources of healthy food.
  • Food deserts are prevalent in low-income neighborhoods.
  • Fast food is more accessible and affordable than fresh produce.
  • Example: 1,300 calories can be bought for $2 in South Bronx bodegas.

  • Example disparities: Baltimore (20-year life expectancy difference), Cleveland (26-year difference).

• Impact of Obesity on Society

  • Obesity drives chronic diseases like diabetes, cardiovascular diseases, stroke, and some cancers.
  • Healthcare costs exceed 2 trillion dollars due to obesity-related health issues.

• Community Involvement and Interventions

  • Need for interventions that make healthy living easier.
  • Encourage community participation in creating open spaces, parks, and grocery store developments.

Conclusion
