Childhood obesity is a significant public health challenge, disproportionately affecting residents of low-income urban neighborhoods. This analysis highlights the critical role of food deserts—areas with poor access to affordable, nutritious food—as an environmental determinant that drives higher rates of obesity in these communities.

  • Affordability: Corner store pricing often makes nutritious options unaffordable, forcing reliance on cheaper, energy-dense foods to ensure food security.
• Health Outcomes: The prolonged exposure to this poor food environment during critical developmental years is strongly correlated with increased childhood BMI and a higher risk of developing chronic diseases, such
