Environmental and Policy Approaches to Increase Physical
  Activity: Community-Scale Urban Design Land Use Policies

 



Center for Disease Control, February 19, 2013

Community-scale urban design land use policies and practices involve the efforts of urban planners, architects, engineers, developers, and public health professionals to change the physical environment of urban areas of several square miles or more in ways that support physical activity. They include the following.

  • Design elements that address:
    • Proximity of residential areas to stores, jobs, schools, and recreation areas
    • Continuity and connectivity of sidewalks and streets
    • Aesthetic and safety aspects of the physical environment

  • Policy instruments such as zoning regulations, building codes, other governmental policies, and builders’ practices

Summary of Task Force Recommendations & Findings
The Community Preventive Services Task Force recommends design and land use policies and practices that support physical activity in urban areas of several square miles or more based on sufficient evidence of effectiveness in facilitating an increase in physical activity.

Results from the Systematic Reviews
Twelve studies qualified for the review and evaluated a variety of effect measures.

  • Most of the studies compared the behavior of residents in automobile-oriented (or suburban) communities with those in traditional (or urban) communities.

  • Overall, the median improvement in some aspect of physical activity (e.g., number of walkers or bicyclists) was 161%.

  • Additional benefits that may have been brought about by these interventions included:
    • Improvements in green space
    • Increased sense of community and decreased isolation
    • Increased consumer choice for places to live
    • Reduced crime and stress

  • Increased walking and bicycling on urban streets, although beneficial, also pose the risk of increased injury to pedestrian or cyclist, because of increased exposure to motor vehicles.

These results were based on a systematic review of all available studies, conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice and policy related to physical activity.

The Community Preventive Services Task Force
The Task Force is an independent, nonfederal, uncompensated body of public health and prevention experts, whose members are appointed by the Director of CDC. Task Force members:

  • Oversee the prioritization process for which systematic reviews to conduct

  • Participate in development and refinement of review methods

  • Serve as members of individual review teams

  • Consider the findings of all reviews and issue recommendations and findings to help inform decision making about policy, practice, research, and research funding in a wide range of U.S. settings
