Playability: Built and Social Environment Features That Promote Physical Activity Within Children

The role of neighbourhood built and social environments in shaping children's physical activity has received increasing interest over the past 10 years. We reviewed recent evidence published between 2011 and 2014. Most of the recent evidence continues to be cross-sectional. Few macrolevel neighbourhood attributes were consistently associated with physical activity in the expected direction. The strongest evidence for associations between neighbourhood attributes and physical activity with was for the transportation environment, particularly in relation to proximity to school and transport-related physical activity. There was intermediate evidence that neighbourhood walking/cycling infrastructure and pedestrian safety structures are associated with transportrelated PA. Recent evidence on associations between the neighbourhood built and social environment and children's PA is modest. Stronger study designs and greater attention to conceptual-matching and specificity of measures are critical to advance the evidence base.
