A new study involving CRESH researchers on neighbourhood built environments and  transport and leisure physical activity has recently been published in the journal Environmental Health Perspectives. The New Zealand study collected data on the urban built environment (destination access, street connectivity, dwelling density, land-use mix and streetscape quality) and surveyed 2,033 adults who lived in 48 New Zealand neighbourhoods. The findings suggested associations of neighbourhood destination access, street connectivity, and dwelling density with self-reported and objectively measured PA were moderately strong.  You can find the paper here: http://dx.doi.org/10.1289/ehp.1104584
