As the previous post mentioned, although many parents and health practitioners prefer working with the diet plus exercise method of controlling childhood obesity, official policies will now support that model to a much lesser extent.
As Gina Kolata reported for The New York Times, some major research projects have been less than encouraging. Back in the 1990s, the National Institutes of Health sponsored two very sizable and careful studies. Could weight gain in children be prevented at school, through the expansion of physical education programs? How about cafeteria meals designed to be more nutritious?
What if students were taught more intensively about good eating and lots of exercise? What if parents were also brought into the picture? Kolata writes,
One study, an eight-year, $20 million project sponsored by the National Heart, Lung and Blood Institute, followed 1,704 third graders in 41 elementary schools in the Southwest… Some schools got intensive intervention, while others were left alone.
In the intervention schools, students changed their eating habits to include slightly less fat, but not much else happened. The investigators had to regretfully declare that body weights had not noticeably shrunk. However, there still is no universal agreement on the failure of diet and exercise. Kolata’s article also included some paragraphs that cast a shadow over the controversial new AAP proposals:
It takes years for doctors to start using new guidelines, noted Dr. Louis Aronne, an obesity medicine specialist at Weill Cornell Medicine in New York. “The ones for adult obesity have never really been adhered to,” he noted. “Adults with obesity are already advised to get surgery or drug treatment, but just 2 percent ever do.”
For The Washington Post, Ariana Eunjung Cha listed the three most important new guideline concepts that the public is meant to grasp:
1. Obesity is a chronic medical condition, not primarily a consequence of lifestyle choices.
2. Medications are a tool that can be used in children 12 and older in a safe manner. Bariatric surgery can also be considered for severe obesity in children 13 and older.
3. More must be done to ensure access to treatments for all children who need them.
Many health professionals and laypersons would prefer to stick with emphasizing healthy eating and increased exercise, ideas which although now relegated to an inferior position, are not entirely abandoned. The new guidelines still include them in the preferred method of first resort, known as Intensive Health Behavior Lifestyle Treatment, or IHBLT.
As summarized by Claire McCarthy, M.D.:
This involves face-to-face, family-based, multidisciplinary counseling on nutrition and physical activity, preferably based in your community and connected to community resources. To make a difference, it should involve at least 26 hours over at least three to 12 months.
This will be discussed further.
