Summary of Community Preventive Services Task Force Recommendation

The Community Preventive Services Task Force (CPSTF) recommends park, trail, and greenway infrastructure interventions when combined with additional interventions to increase physical activity.

There were no economic studies that evaluated park, trail, and greenway infrastructure interventions when combined with additional interventions. However, CPSTF finds the economic benefits exceed the cost of park, trail, and greenway infrastructure interventions when implemented alone.

Major Findings

CPSTF recommends park, trail, and greenway infrastructure interventions when combined with additional interventions based on evidence from a systematic review of 21 studies from 20 publications (search period through March 2019). Evidence showed interventions led to the following:

  • Median increase of 17% in the number of people engaging in moderate-to-vigorous physical activity (7 studies)
  • Median increase of 18.3% in the number of people using the park, trail, or greenway (9 studies)

The CPSTF economic finding for park, trail, and greenway infrastructure interventions when implemented alone is based on evidence from a systematic review of 8 studies (search period through March 2022). Evidence showed a median benefit to cost ratio of 3.1 (7 studies).

What are Park, Trail, and Greenway Infrastructure Interventions?

These interventions improve the built and natural environments by creating or enhancing one of the following public locations for physical activity, relaxation, social interaction, and enjoyment.

  • Parks—designated public areas that often combine greenery with paths, facilities for physical activity and recreation, and places for relaxation and social interaction.
  • Trails and Greenways—routes for walking, hiking, or cycling in urban, suburban, or rural areas (e.g., “rails to trails” conversion projects). These may involve street conversions that provide opportunities for walking and cycling (most often in urban areas).

What are additional interventions?

These include community engagement; public awareness activities; programs that offer structured opportunities for physical activity and social interaction; access enhancements such as transportation connections, street crossings, and expanded hours of operation; or a combination of these components.

Why is This Important?

  • Physical activity has immediate benefits, such as reducing anxiety and improving sleep.1
  • Regular physical activity can produce long-term health benefits, including the prevention or reduction of risk for more than 20 chronic diseases like heart disease, some cancers, stroke, and type 2 diabetes.1
  • Overall, 11.1% of aggregate healthcare expenditures are associated with inadequate physical activity (i.e., inactive and insufficiently active levels).2
  • To attain substantial health benefits, federal physical activity guidelines recommend adults perform at least 150 minutes a week of moderate-intensity physical activity.3

Established in 1996 by the U.S. Department of Health and Human Services, the Community Preventive Services Task Force (CPSTF) is an independent, nonfederal panel of public health and prevention experts whose members are appointed by the director of CDC. CPSTF provides information for a wide range of decision makers on programs, services, and other interventions aimed at improving population health. Although CDC provides administrative, scientific, and technical support for CPSTF, the recommendations developed are those of CPSTF and do not undergo review or approval by CDC.
