A few months ago, after several months of considerable foot dragging, I wrote that I have accepted the American Academy of Pediatrics’ proclamation that we should begin to treat obesity as a disease.
While it may feel like we are just throwing in the towel, it sounds better if we admit that we may have reached the threshold beyond which total focus on prevention is not going to work.
I continue to be troubled by the lingering fear that, in declaring that obesity is a disease, we will suspend our current efforts at preventing the condition. Granted, most of these efforts at prevention have been woefully ineffective. However, I still believe that, much like ADHD, the rise in obesity in this country is a reflection of some serious flaws in our society. On the other hand, as an inveterate optimist I have not given up on the belief that we will find some yet-to-be-discovered changes in our societal fabric that will eventually turn the ship around.

With this somewhat contradictory combination of resignation and optimism in mind, I continue to seek out studies that hold some promise for prevention while we begin tinkering with the let’s-treat-it-like-a-disease approach.
I recently discovered a story about one such study from the Center for Economic and Social Research at the University of Southern California. Using data collected about adolescent dependents of military personnel, the researchers found that “exposure to a more advantageous built environment for more than 2 years was associated with lower probabilities of obesity.” Because more than half of these teenagers were living in housing that had been assigned by the military, the researchers could more easily control for a variety of factors some related to self-selection.
Interestingly, the data did not support associations between the adolescents’ diet, physical activity, or socioeconomic environments. The investigators noted that “more advantageous built environments were associated with lower consumption of unhealthy foods.” However, the study lacked the granularity to determine what segments of the built environment were most associated with the effect they were observing.
Like me, you may not be familiar with the term “built environment.” Turns out it is just exactly what we might expect – anything about the environment that is the result of human action – buildings, roadways, dams, neighborhoods – and what they do and don’t contain. For example, is the adolescent living in an environment that encourages walking or one that is overly motor vehicle–centric? Does his or her neighborhood have easily reachable grocery stores that offer a range of healthy foods or does the teenager live in a nutritional desert populated only by convenience stores? Is there ample space for outdoor physical activity?
The authors’ observation that the adolescents who benefited from living in advantageous environments had a lower consumption of unhealthy foods might suggest that access to a healthy diet might be a significant factor. For me, the take-home message is that in our search for preventive strategies we have barely scratched the surface. The observation that the associations these researchers were making was over a relatively short time span of 2 years should give us hope that if we think more broadly and creatively we may be to find solutions on a grand scale.
Over the last century we have built an environment that is clearly obesogenic. This paper offers a starting point from which we can learn which components of that environment are the most potent contributors to the obesity epidemic. Once we have that information the question remains: Can we find the political will to tear down and rebuilt?
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.
