A new study in Cancer Epidemiology, Biomarkers, and Prevention by PRC Director Karen Glanz, PhD, MPH, and co-authors supports evidence that individuals may obtain higher levels of physical activity in more walkable environments. Their findings “also suggest that the built environment may be a more important factor than the natural environment when considering routine location-based physical activity. As the popularity of GPS- and accelerometer-enabled smartphones grows alongside accelerometry-based consumer wearable devices (55–58), these novel streams of spatial energetics data will provide translational insights into potential interventions to improve urban planning and green space development to optimize opportunities for physical activity and reduce cancer risk.”
