An excellent idea I say, considering that diabetes mellitus will be a leading cause of morbidity and mortality for the foreseeable future.
Since most people rarely stick to their treatment, and by that I mean their lifestyle, they certainly need some discipline while they're young. Not taking them to these camps, or any activity related to it, is like not taking them to school just because they might not want to. They obviously don't want to, they don't know what's good for them yet.
Obesity is associated with an increase in mortality, with a 50-100% increased risk of death fromall causes compared to normal-weight individuals. And sadly, obesity is the second leading cause ofpreventable death in the United States. Just imagine how much would it mean, for the individual and the health care system, to implement such measures as the one suggested in this thread.
