 The study aims to identify built environment attributes associated with health-enhancing levels of physical activity, PA, in older adults, greater than or equal to 65 years old. It reviews and quantifies findings on built environmental correlates of PA, and investigates differences by type of PA and environmental attribute measurement. The results show that positive environmental correlates of PA include walkability, safety from crime, overall access to destinations and services, recreational facilities, parks, public open space, shops, commercial destinations, greenery and aesthetically pleasing scenery, walk-friendly infrastructure, and access to public transport. The study also found that the strength of evidence of associations of specific categories of environment attributes with PA differed across PA and environmental measurement types. Higher quality research is needed to identify underlying mechanisms and addressing consistencies in findings. This article was offered by David W. Barnett, Anthony Barnett, Andrea Nathan, and others.
