We’ve known for several years that unhealthy behaviors are contagious and spread within social networks. But it turns out that healthy behaviors are contagious, too! When someone exercises, the people around them are more likely to do so as well. When someone loses weight, their trusted social network is more likely too also lose weight. This may seem intuitive, but groundbreaking new research is showing us just how powerful these forces are and igniting our imagination about how we can use this knowledge to improve the health of large populations.

    • Why We Conducted This Research• There is strong evidence that obesity spreads through social networks• Given our focus on weight reduction, we aimed to investigate whether these same social influence processes can be harnessed to promote healthy behavior change• No one had examined whether the social component of wellness program enhances outcomes Copyright © 2012 ShapeUp, Inc.

    • About Shape Up Rhode Island• Annual workplace-based campaign to promote exercise and weight loss• Thousands participate each year• Team competition (5-11 members)• 12 week online program includes personal and team progress tracking, weekly newsletters, community events• Yields significant weight losses (-3.7kg)1 and increases in physical activity (+2,300 steps)21Wing et al., Obesity, 2009; 2Leahey et al., Prev Med, 2010 Copyright © 2012 ShapeUp, Inc.

    • The Team Effect For Weight Loss • Team members influenced individual weight loss outcomes • Individuals on the same team achieved similar weight losses (ICC = 0.10)Leahey et al., Obesity, in press Copyright © 2012 ShapeUp, Inc. Confidential & Proprietary. 23
    • Optimal Environment For Weight Loss • Effects of team characteristics on individual weight loss Those who reported greater teammate social influence for weight loss had higher weight losses Having more teammates in the weight loss division yielded greater weight lossesLeahey et al., Obesity, in press Copyright © 2012 ShapeUp, Inc. Confidential & Proprietary. 24
    • Clinically Significant Weight Loss • Team membership also influenced the odds of achieving a clinically significant (i.e. 5%) weight loss, which is associated with reduced risk for cardiovascular disease and diabetes • Achieving a 5% weight loss clustered within teams (ICC=0.09)Leahey et al., Obesity, in press Copyright © 2012 ShapeUp, Inc. Confidential & Proprietary. 25
    • Optimal Team Characteristics• Effects of team characteristics on individuals achieving a 5% weight loss Greater social influence for weight loss increased the likelihood Having more teammates in the weight loss division increased the likelihoodLeahey et al., Obesity, in press Copyright © 2012 ShapeUp, Inc. Confidential & Proprietary. 26
    • Team Effect For Physical Activity• Team members influenced individual physical activity outcomes• Individuals on the same team achieved similar increases in physical activity (ICC = 0.09)Leahey et al., Prev Med, 2010 Copyright © 2012 ShapeUp, Inc. Confidential & Proprietary. 27
    • Optimal Team Characteristics• Team characteristics influenced individual activity outcomes Individuals on teams that had high levels of activity within the first two weeks of the Shape Up program achieved the greatest increases in activityLeahey et al., Prev Med, 2010 Copyright © 2012 ShapeUp, Inc.

    • Key Insights From This Research• Social networks impact weight loss and physical activity• Wellness programs should tap the organic social influence potential of coworkers, friends, and family to enhance weight loss and activity outcomes Ensure that everyone on the same team is working towards a similar health goal Set team goals to maximize social accountability and encourage regular reporting of individual progress Promote a culture of social support and cohesion among team members by offering teambuilding activities Copyright © 2012 ShapeUp, Inc.

    • Next Steps For Our Research• Conduct a randomized trial comparing an “optimal” team environment to an “average” or “poor” team environment and examine the effects on weight loss and physical activity outcomes• Further examine the social influence processes by which social networks impact health Social norms Social modeling Peer accountability Social support Copyright © 2012 ShapeUp, Inc.
