The researchers used artificial intelligence (AI) to assess the presence of sidewalks and crosswalks in the images and compared this data with information on obesity and diabetes prevalence. The results showed that neighborhoods with greater pedestrian access had lower rates of obesity and diabetes. But the link between sidewalks and health was less clear.
The authors of the study noted that the accuracy of AI data may be limited as images may contain errors due to obstructions such as cars or shadows. They also stressed that the use of data from digital sources should be combined with expert knowledge to ensure that interventions are effective.
