The team lead by researchers from University of Washington, Seattle, downloaded nearly 150,000 high-resolution Google Map satellite images of select neighbourhoods in four cities - Los Angeles (California); Memphis (Tennessee); San Antonio (Texas) and Seattle (Washington State).
"The extraction of built environment showed that physical characteristics of a neighbourhood (presence of parks, highways, green streets, crosswalks, diverse housing types) can be associated with variations in obesity prevalence across different neighbourhoods," the researchers wrote.
Obesity has been linked to factors such as genetics, diet, physical activity and the environment.
However, evidence indicating associations between the built environment and obesity has varied across studies and geographical contexts.
"Understanding the association between specific features of the built environment and obesity prevalence can lead to structural changes that could encourage physical activity and decreases in obesity prevalence," said the researchers.
Behavioural traits that encourage unhealthy food choices and a sedentary lifestyle have been associated with features in the social and built environment.
The built environment can influence health through the availability of resources, such as housing, activity and recreational spaces, and measures of community design, the findings showed.
According to the researchers, assessing an area's obesity rates may help city planners develop more green areas to help people remain more physically active.
