Childhood Obesity And Food Insecurity



Services Provided:

  • GIS Support,
  • Data spatialization,
  • Exploratory Geospatial analysis,
  • Documentation.

Project Objective

Client wanted to conduct public health research to explore the dimensions of spatial inequality and community well-being, in particular examining the relationship between food deserts (an area with limited access to retail food stores) and childhood obesity.

Tessellations utilized Geographic Information System (GIS) techniques to identify food desert areas and analyzed children’s body mass index (BMI) data to determine the extent to which these food deserts are positively associated with increased incidence of child overweight.

Scope of Services

  • Provided GIS support for a long term study for childhood obesity and food security,
  • Data collected by scientists across multiple states was geocoded, spatialized and represented cartographically,
  • Collected data was augmented with roads, administrative boundaries, and addresses of grocery stores and fast food chains were then geocoded,
  • Exploratory geospatial analysis was conducted to determine if there were any correlations between the distribution of children from food-insecure households and obesity

Notable Accomplishments

  • Different spatial and statistical clustering techniques were utilized for analyzing the relationship between children with high BMI to the location of food deserts.
