Social environments such as
school, work, family and friends can significantly influence an individual's
level of physical activity. However, characteristics of our communities such
as the accessibility and location of parks, trails, sidewalks, and
recreational centers as well as street design, density of housing, and
availability of public transit may play and even greater role in promoting
or discouraging an individual or family's level of physical activity. There
are also significant environmental barriers from water and air pollution to
crime and dangerous automobile traffic. CDC 1997 |
