A recent study led by the University of Southern California examined whether children living in a community designed according to smart growth principles are more physically active than children living in conventional suburbs. Children living in the smart growth community engaged in more physical activity within a few blocks from home, and at places they walked to and with friends, compared with children living in conventional suburbs.
