First, we are aware of that program. I think you have to be cognizant that in any program that's tasked to deal with obesity in childhood--and probably the Sierras program is a little better than the most heavily touted research program, which has a success rate of about 45%--once the cat's out of the bag, it's very difficult to get the cat back in.
So I would still argue that primary prevention is the way to go, but you're right, since so many children and youth are affected, don't we need to do something about it? The particular Sierras situation is a very costly program, but they are very successful. One of the things we would like to see long term from that program is what happens when they go back into society. Is it a long-term solution or is this actually a quick fix? That's still not clear from a research perspective, in my estimation, from what I've been able to see.
I do think we're going to need to tackle both of these issues. It's just that, in my opinion and in the opinion of many other experts on this issue, primary prevention will go a lot further than trying to deal with it once it has happened.
