Environmental access to PA [physical activity] resources (determined via GIS-based assessment of the number of gyms, schools, trails, parks and athletic fields within 0.5 miles of each participant's home) moderated the association between social support and PA; among adolescents with high levels of environmental resources, greater social support was associated with students participating in a greater number of sports in school, whereas no such relationship emerged among adolescents with low environmental resources.

This is the first time that this link has been established in research outside the US, where healthy 'food deserts' have been found in areas of social deprivation.
