Exposure to Neighborhood Walkability and Residential Greenness and Incident Fracture
Authors' conclusion
This population cohort study suggested that long-term exposure to neighborhood walkability and residential greenness were both associated with lower risk of incident fracture. The benefits of greenness increased in more walkable areas.
