1 Background and Rationale I n 1995, Shiriki Kumanyika, now associate dean of health promotion and disease prevention and professor of epidemiology at the University of Pennsylvania Perelman School of Medicine, began reading a report from the British Recreation Department about building a network of bicy- cle paths in the United Kingdom. The rationale for the network was that families needed to spend more time together. The report did not mention obesity, but Kumanyika immediately realized that such a network would have an incidental co-benefit for prevention of childhood obesity by getting children to engage in more physical activity.

2 ALLIANCES FOR OBESITY PREVENTION ington, DC, on October 20, 2011, the workshop was titled Alliances for Obesity Prevention: Finding Common Ground. The organizers chose the title carefully, Kumanyika explained in her opening remarks. The term “partnership” had been considered; however, that term can be interpreted in many different ways and often is applied to public-private partnerships, which were not the focus of the workshop. The planning committee preferred the term “alliances” because it better expressed the focus of the workshop—to explore potential relationships involving seemingly disparate nonprofit or government organizations that may have common ground relevant to obesity prevention. Core obesity prevention groups (e.g., public health departments) are likely to form alli- ances to the extent that they expect obesity prevention co-benefits to accrue as another organization or sector pursues its primary, non-obesity-focused goals. This allows both groups to leverage each other’s strengths to achieve mutual benefits. Thus, alliances can form between organizations that have different objectives but have identified issues of mutual interest on which they can work together, even if only for a finite period of time, to achieve a discrete goal. The workshop had three objectives, as described in its statement of task (see Appendix C): • to hear from organizations, movements, and sectors with the potential to be allies for obesity prevention, and to identify com- mon ground and engender dialogue among them; • to discuss whether and how to develop innovative alliances that can synergize efforts and resources, accelerate progress, and sustain efforts toward obesity prevention; and • to learn from other initiatives that have benefited from forming alliances to synergize efforts and resources and accelerate progress. It should be noted that, given limitations of both time and scope, the work- shop could not address all issues related to alliances for obesity prevention. SOCIAL MOVEMENTS AND OBESITY PREVENTION The chair of the workshop planning committee, Thomas Robinson, Irving Schulman Endowed Professor in Child Health at the Stanford Uni- versity School of Medicine, has worked extensively on alliances between organizations to prevent childhood obesity, and he elaborated on the ratio- nale for the workshop. Robinson also observed that strategies for the pre- vention of obesity may encompass environmental-, policy-, interpersonal-, or individual-level interventions. The ultimate pathway for all of these

3 BACKGROUND AND RATIONALE approaches is that they rely on changing behavior; if an intervention fails to change behavior, it does not produce the desired effects. Behavioral change depends on two types of motivation. One is motiva- tion to adopt the new behavior and achieve a particular outcome, which Robinson terms outcome motivation. The other is motivation to partici- pate in the intervention itself, which Robinson calls process motivation (Robinson, 2010a). The medical and public health communities tend to focus on outcome motivation. They emphasize the risks of obesity, type 2 diabetes, hyperlipidemia, hypertension, cardiovascular disease, and can- cer (Robinson, 2010a). “Those are the things that we try to persuade the public or patients to pay attention to as motivators to change behavior,” Robinson said. However, research on motivation in children as well as in adults points to an entirely different set of powerful motivating forces. These include fun, choice, control, curiosity, challenge, cooperation, competition, social interaction, sense of accomplishment, peer approval or disapproval, and parental approval or disapproval. These factors, rather than the ultimate outcome of the behavior, are more likely to predict whether a child or an adult will persist at a task or participate in the process of behavioral change (Lepper et al., 2008; Robinson and Borzekowski, 2006). None of these fac- tors is specific to health. Robinson’s question, then, is whether an interven- tion to change a health-related behavior needs to look, feel, sound, smell, or taste like health education. Does the intervention need to have anything to do with health, given that the things that motivate people to change their behaviors often have little or nothing to do with outcomes? These questions have led Robinson to examine what he calls “stealth interventions.” Stealth does not imply deception or manipulation, he said. Rather, the intervention has an effect on physical activity or diet but is centered on a different aspect of motivation (Robinson, 2010a). In other words, although the intervention may target changing obesity, the partici- pant is not motivated by an outcome such as losing weight or being more active but instead is focused on other motivating aspects of the process. Nonetheless, physical activity or dietary changes are beneficial side effects of the intervention. The ideal situation is to target behaviors that are motivating in them- selves. For example, Robinson and his colleagues have used ethnic dance to work with pre-adolescent girls (Robinson et al., 2010). “Physical activity and obesity never enter the lexicon,” he said. “It’s about the costumes, it’s about the music, it’s about learning about your cultural heritage, it’s about the importance of doing dances that your parents did when they were grow- ing up in Mexico.” Another example involves overweight children on sports teams. These children tend not to join sports teams, but they may be much more likely to do so if they are joining a league that is just for overweight

4 ALLIANCES FOR OBESITY PREVENTION kids. The attractions that accompany team sports—teamwork, competition, coaches, uniforms—are highly motivating, and weight loss can be an ancil- lary benefit. Thus one study of team sports for overweight children found that body mass index (BMI) declined in the intervention group compared with a control group even when the controls received nutrition and health education (Weintraub et al., 2008). A prominent challenge is to produce effects of greater magnitude than are currently observed with such stealth interventions. In a search for motivations that cause more dramatic and sustained changes in behavior, Robinson has focused on social and ideological movements (Robinson, 2010b), loosely defined as groups of people or organizations that focus on specific common issues, often to effect change. The classic example is religious movements, in which people with strong religious beliefs can sustain behaviors that differ markedly from social norms. Other social and ideological movements that could have an effect on obesity include • environmental sustainability/climate change; • food justice/urban agriculture; • food safety; • community safety, beautification, and traffic reduction; • human rights/social justice; • anti-globalization/nationalism; • animal protection; • anti-consumerism; • violence and crime prevention; • cause-related fundraising; • energy independence; and • national security/anti-terrorism. As an example, Robinson cited the adolescent girls he sees in his pedi- atric practice who are vegetarians, despite pressures from their parents or communities. They are able to sustain these behaviors over time because of their strong beliefs, which may be based on preventing animal cruelty or protecting the environment. Robinson also highlighted cause-related fundraising, which often has an altruistic component. An example is Team in Training, through which people raise money for the Leukemia & Lymphoma Society3 by training to participate in half-marathons, 10-kilometer races, triathlons, and other sporting events. “There are people who [can’t] walk around a track when they start, who train over a series of months and end up being able to run a half marathon,” Robinson observed. 3 For more information about the Leukemia & Lymphoma Society, see http://www.lls.org/.

5 BACKGROUND AND RATIONALE People have many reasons for joining a social movement. They may make a rational choice in that they see the benefits of joining the movement as greater than the risks. Joining a movement may help form or define an identity, whether a self-identity, a social or collective identity, or a public identity. People may be attracted by the possibilities for social interaction, which provides social support and, especially for stigmatized groups, can enhance feelings of efficacy and performance. Joining a social movement may help people avoid personal failure by exchanging personal responsi- bility for collective responsibility. Finally, emotional responses can be a powerful motivator. As an example of this last factor, Robinson described an experiment he conducted at Stanford with a class called Food and Society. The course covers agricultural policies, labor issues, consumerism, animal rights, ani- mal welfare, environmental issues, and other topics related to food and agriculture that are not necessarily directly related to nutrition and health. When the eating behaviors of students who took this class were compared with those of students who took classes on obesity or public health nutri- tion, the former students were found to have changed their eating behaviors significantly more than the latter students (Hekler et al., 2010). Social movements have the potential to influence public policy through the mobilization of families, governments, markets, and civil society, Robinson observed. In turn, new norms, laws, or regulations can further promote individual change, creating a self-reinforcing feedback loop of change. Piggybacking obesity prevention on existing social movements makes it possible to leapfrog the difficult process of starting a social movement from scratch, Robinson concluded. There are many examples of such move- ments, as illustrated by the workshop presentations, and they are already proving to be highly motivating to segments of the population (Robinson, 2010b). They have the potential to produce dramatic and sustained changes in behavior, and these behavioral changes can be magnified through changes in norms and public policy. Teaming with existing social movements can create many new allies, resources, and strategies for the obesity prevention movement. ORGANIZATION OF THIS SUMMARY Chapter 2 examines a particular alliance in more detail. Mission: Read- iness4 is an initiative led by a group of retired military leaders to enhance military preparedness by reducing obesity and increasing fitness among potential recruits. This initiative has been part of an unexpected alliance, 4 For more information on Mission: Readiness, see http://www.missionreadiness.org/.

6 ALLIANCES FOR OBESITY PREVENTION several workshop participants noted, that can attract attention to and gen- erate change for obesity prevention. Chapters 3 and 4 summarize the presentations and subsequent discus- sions of two panels. The first panel looked at groups and programs focused on food and nutrition; the second looked at groups and programs focused on physical activity and the built environment. Together, these two panels represented a sizable list of potential allies in the effort to prevent childhood obesity, and pointed toward a much larger list. Chapter 5 examines the conditions necessary for alliances to form and endure, while Chapter 6 describes some of the more practical aspects of building and maintaining alliances. Finally, Chapter 7 summarizes the closing observations about work- shop themes made by a member of the Committee on Childhood Obesity Prevention.
