Interview: Daniel Hatfield - Inspiring active lifestyles in Children
We met Dan through a friend we ran into while looking into the impressive, Boston-based, multi-disciplinary obesity initiative, Child Obesity 180. Currently pursuing a PhD in Food Policy & Applied Nutrition at Tufts University, Hatfieldâs research focuses on the cardiometabolic and psychosocial impact of physical activity among children and adolescents, as well as the motivational factors that lead young people to move more. A former high-school teacher and coach, Dan is especially interested in physical activity and nutrition policies and programming for children in underserved communities. As a 2010-2011 Albert Schweitzer Fellow, he helped launch a health and fitness program for middle-school-aged boys in East Boston and remains active in that community. We interviewed Dan to discuss his hands-on experience and to glean a street level perspective on what motivates kids to change behavior, how Quantified Self technologies can work with children and the kind of collaborative effort it will require to systemically address childhood obesity.
 IT: What is your research focused on?
DH: Right now, there are a couple of pieces. First, Iâm using a national data set to look at the benefits of physical activity in terms of cardiometabolic health in children, independent of body mass index. Weâre asking, what are the benefits for an overweight or obese child being active or fit, even if you hold weight status constant? In community health settings, BMI is often the metric that people focus on. If it doesnât move then they think theyâve failed.  To me, healthy BMI is one important outcome related to physical activity. But there are lots of other waysânot just physiologically, but also socially and psychologicallyâthat exercise is beneficial to kids.
 For another part of my research, Iâm working with an after-school physical activity program that mostly serves overweight and obese children and teens. Weâre building a theory-based curriculum that lines up with their unique needsâweâre asking, âHow can we tailor what we do for kids who are underfit, or who have had limited opportunity to feel successful in physical activity and sport?â  Then weâre evaluating the program with a variety of measures, looking not just at BMI but also at other outcomes like cardiorespiratory fitness, physical activity behaviors, and child self-perceptions.
 IT: You also work with programs in East Boston â an area thathas some of the highest rates of childhood obesity in the city. What makes this particular neighborhood more vulnerable to obesity than other Boston neighborhoods?
 DH:  Demographically, East Bostonâs population is mostly low-income and mostly Latino.  If you look at national trends, kids in these demographic groups are much more likely to be overweight or obese compared with the general population.
 The âwhyâ behind these trends is more complicated. In East Boston, like other places, the food and physical activity environments present all kinds of challenges.  For example, our children often donât have opportunities to participate in sports programs, or access to quality PE in school. On the diet side, thereâs only one grocery store in East Boston, but tons of fast-food joints. Lots of parents work long hours and financial constraints make it hard to buy and prepare healthy foods. In the end, of course kids make some choices in terms of their diets and levels of physical activity, but those choices are often very much constrained by the environments those kids occupy.
 IT: When you set out to build an after-school fitness program, what considerations, relationships and data are most influential in the design?
 DH: Iâm a big fan of self-determination theory, which suggests that health behaviors can be predicted by an individualâs perceived competence, their sense of relatedness, and their level of autonomy.  In my experience, this particular theory offers a powerful framework for understanding why our kids are active or not, and so weâve thought a lot about these constructs as weâve developed our curriculum. Weâve asked, how can we create a culture where kids feel related to each other and to their coaches? How can we build lessons that help kids feel more confident in physical activity and sports in ways they might not be coming into the program? And how can we empower them to make autonomous choices?  In my experience, trying to force kids to be active doesnât really work, especially in terms of building sustainable habits. On the other hand, Iâm often amazed what happens when you give kids choices. Even kids who really struggle fitness-wise will often choose the more challenging path if theyâre just given the opportunity to make that choice for themselves. Â
 IT: How do you make something like running âfunâ and what aspects of the program do you think will be most influential in getting kids to continue to run after the program concludes?Â
 Programs like ours have to engage kids in things they actually enjoy doing. First, we tailor the curriculum so it meets kids where they are. Early on, we donât try to tell them, âgo run two miles.â Instead, we might have them walk a short lap and then jog another, and repeat that interval a few times.  Then weâll help kids set different walk-to-run ratios that are challenging but achievable for them. Everyone likes to feel like theyâre making progress, so once we get a kid who could only walk one lap coming in to jog two without taking a break, the pride and satisfaction really carry the child forward.  We also frame lots of our activities as relays or games, but avoid hyper-competitive scenarios where kids might feel discouraged. In some cases itâs tempting to jump right into competitive game play, but youâve got to remember that for a kid who lacks confidence thatâs not at all fun. Instead, we create lots of games that are less competitive but still fun and that build basic skills in the process. Really, our main focus in on helping kids challenge themselves to get better, instead of focusing on beating someone else.
 IT: In a 2010 interview you said, âHow we eat and move relates to so many complex physiological and emotional factors at the individual level, not to mention all the broader social and environmental issues that come into playâŚ.Viable solutions to the obesity issue will have to address this full range of factorsânot just the individual child, but also the built environment, home, schools, and so on.â While fitness programs, like your own, effectively address one or two facets of the problem, what is needed from a holistic sense, to connect these disparate solutions?
 DH: Itâs hard. I might help kids to be more fit, or to enjoy being active, but if they donât have a safe place to play in their community there are limits to the behavior change weâll see outside the context of our program.  Public health practitioners are increasingly recognizing that in order to change behavior you really have to move beyond the individual and think about environments.  Individual knowledge and skills are necessary to get people to engage in healthier behaviors, but theyâre not enough if environments donât make healthier choices the easier choices.   For people to eat healthfully, healthy food needs to be accessible. That doesnât just mean getting more produce in the grocery storeâit also means ensuring those healthy foods are affordable and consistent with the culture of the community and what people actually want to buy. The same goes for the physical activity environment. We have to design parks and streets that are safe to walk and bike on. I talk with lots of kids who who say, âWhen Iâm at home I have to stay inside all day because my parents donât want me to go out and play in our neighborhood.â Those are issues that have to be addressed. Solutions will require real investment and collaboration across sectorsâfederal and local governments, corporate entities, non-profits, academics, and community leadersâto make the healthier choice the easier one.Â
 IT: Do you envision a useful role for technology in coalescing solutions? If so, how might that play out?
DH: Technology gets vilified a lot. Some people think of screens of any sort and theyâre immediately put offâmore screens, the conventional wisdom goes, mean more sedentary time.   At the same time, technologyâs not going anywhere. Kids are going to play video games, watch TV, and be on their cell phones. We can and should encourage kids to get out from behind screens, but burying your head in the sand to modern realities doesnât strike me as a realistic approach.  We should also think about opportunities to leverage technology to motivate and enable kids to be more physically active. Thereâs been some interesting work around active gaming, for exampleâif you can get kids to actually play video games that get them up and moving around instead of sitting in front of a TV, itâs a step in the right direction. The evidence has been mixed on active gaming consoles, but I think thereâs promise there. There are also the Quantified Self technologies like Fitbit and Runkeeper that represent other interesting opportunities. Many of these QS technologies target adults more than children, though, so I think there may be a significant, untapped opportunity in leveraging these technologies with kids. Iâm especially interested in how we can make these emerging options accessible for high-risk populations, like kids in low-income communities. Â
 IT: Though I recognize the many environmental factors contributing to sedentary behavior, the idea that in 2012, kids require fitness programs, exciting products, and rewards to be physically activity elicits this sad, nostalgic response in me. It seems that under ideal conditions, childrenâs exercise has always just been a secondary outcome to play and having fun. Do you think that outside-offline play is losing a kind of battle with the sedentary consumption of entertainment media? If so, how do you think we can âreanimateâ the outside world in childrenâs minds again?
 DH: I think itâs a challenge. Weâre saturated with media, and it can be hard to compete with hyper-stimulating video games that are very passive and donât require a whole lot of cognitive work for kids. But at the same time, I donât think that the world needs to be âreanimatedâ exactlyâengaging with the world around you in creative ways will always be fulfilling and exciting in ways that passive consumption just canât be.
 Thereâs definitely a school of thought that says using extrinsic motivatorsâlike incentives or rewards or other gimmicksâwill kill intrinsic motivation and impair long-term behavior change.  Thereâs a reasonable argument there, but I believe thereâs a middle ground. Many of the kids I work with benefit from extrinsic rewards to encourage them across the initial and significant hurdle of being physically active again. In some cases, it might be a necessary step to building toward the kind of deeper intrinsic motivation we ultimately want to engender.  Â
