Abstract:
|
Body mass index (BMI) and demographics were obtained for children ages 3-16 years old using the Regenstrief Electronic Medical Record System; patient-level environmental variables were developed from U.S. Census data and remote sensing image using Geographic Information Systems (GIS). The association between childhood obesity and environmental risks was investigated in a spatial logistic regression model. Our results showed that neighborhood greenness (measured by the Normalized Difference Vegetation Index) and distance to supermarkets were significant predictors of childhood obesity and these associations differed between children living in high population density region versus low population density region.
