Community-based social support for physical activity

Evidence Rating  
Scientifically Supported
Evidence rating: Scientifically Supported

Strategies with this rating are most likely to make a difference. These strategies have been tested in many robust studies with consistently positive results.

Health Factors  

Community-based social support interventions for physical activity combine physical activity opportunities and social support to build, strengthen, and maintain social networks that encourage positive behavior changes. Interventions can also include education, group or individual counseling, or plans tailored to individual needs. Examples of community-based social support interventions include walking groups, setting up an exercise buddy system, and making contracts, goals, or physical activity plans with others1, 2, 3.

Expected Beneficial Outcomes (Rated)

  • Increased physical activity

  • Improved physical fitness

  • Improved health outcomes

  • Improved mental health

Evidence of Effectiveness

There is strong evidence that community-based social support interventions for physical activity increase physical activity1, 2, 4, 5, 6 and physical fitness among adults1, 2. Such interventions have also been shown to provide health benefits such as reductions in indicators of cardiovascular risk, including reduced blood pressure, body mass index (BMI), and total cholesterol2, 4, and depression symptoms2.

Social support for physical activity increases physical activity among older adults, especially when interventions include family support7. Middle-aged women enrolled in a weight loss program are more likely to lose weight when they experience social support from friends and family8.

Community-based social support interventions for physical activity with a duration of at least 6 months are more effective than shorter interventions. Interventions that focus on older adults are more effective than those for younger adults6. Some studies suggest that such interventions are more effective when designed for both genders6, while others suggest that tailoring interventions for women increases effectiveness5. Interventions led by lay people appear as effective as those led by professionals6.

Community-based social support interventions have been shown to increase physical activity among adults in socio-economically disadvantaged neighborhoods3, 4. Residents of low income communities with more physically active social networks are more likely to meet recommended physical activity guidelines than residents with less active social networks9. Interventions to increase perceptions of safety may increase participation in walking groups and other community-based social support interventions in socio-economically disadvantaged neighborhoods10.

Overall, community-based social support interventions may not increase physical activity and physical fitness among adolescents11 or children3. However, adolescents with low levels of perceived social support from family and friends appear more likely to engage in unhealthy weight control behaviors than peers with higher levels of social support12. Additional evidence is needed to determine effects on adolescents and children.

Community-based social support interventions for physical activity are considered cost effective13.

No impact on disparities likely

Implementation Examples

Community-based social support interventions for physical activity are implemented throughout the country. Examples of community wide interventions include Detroit’s Walk Your Heart to Health14, Huntsville’s We Walk Huntsville15, Oregon Walks16, and Community Healthy Activities Model Program For Seniors17. Individuals can also set up their own walking group, buddy system, or workout partnership.
