This session entitled "Food Deserts and Obesity Risk" focuses on the connection between limited access to affordable, nutrient-rich foods and obesity risk (and its related health consequences and inequities). We will discuss social, economic, and environmental factors that define a food desert and highlight evidence-based community interventions and policy strategies that seek to improve access to healthy foods for people who are food insecure, which ultimately helps mitigate obesity risk. "Public health," " urban planning," and "nutrition education" will be highlighted as critical community, organizational, and institutional ways to seek to ameliorate obesity risks in food deserts and promote equitable health outcomes. Our case studies and research can inform ideas and next steps to address the ongoing issue of food insecurity and promote healthier communities.
