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 others (CG-Physical activity, Hanson 2015, Cleland 2012*).

Evidence of Effectiveness
There is strong evidence that community-based social support interventions for physical activity increase physical activity (CG-Physical activity, Hanson 2015, Schulz 2015*, Bock 2014*, Kassavou 2013) and physical fitness among adults (CG-Physical activity, Hanson 2015). 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 cholesterol (Hanson 2015, Schulz 2015*), and depression symptoms (Hanson 2015).
Social support for physical activity increases physical activity among older adults, especially when interventions include family support (Smith 2017a). Middle-aged women enrolled in a weight loss program are more likely to lose weight when they experience social support from friends and family (Kiernan 2012).
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 adults (Kassavou 2013). Some studies suggest that such interventions are more effective when designed for both genders (Kassavou 2013), while others suggest that tailoring interventions for women increases effectiveness (Bock 2014*). Interventions led by lay people appear as effective as those led by professionals (Kassavou 2013).
Community-based social support interventions have been shown to increase physical activity among adults in socio-economically disadvantaged neighborhoods (Schulz 2015*, Cleland 2012*). 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 networks (Child 2017*). Interventions to increase perceptions of safety may increase participation in walking groups and other community-based social support interventions in socio-economically disadvantaged neighborhoods (Kwarteng 2018*).
Overall, community-based social support interventions may not increase physical activity and physical fitness among adolescents (van Sluijs 2011*) or children (Cleland 2012*). 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 support (Vander Wal 2012*). Additional evidence is needed to determine effects on adolescents and children.
Community-based social support interventions for physical activity are considered cost effective (Roux 2008*).
Impact on Disparities
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 Health (Detroit WYHH), Huntsville’s We Walk Huntsville (WWH-Group walks), Oregon Walks (Oregon-WG), and Community Healthy Activities Model Program For Seniors (CHAMPS). Individuals can also set up their own walking group, buddy system, or workout partnership.
