Well, unfortunately, the issue is a lot more complicated than just kids overeating... There is a kind of correlation going on with the weight of many people, and incidence of Diabetes, BUT...  in many studies, light is being shed on the fact that the same thing that is causing the Type 2 is causing the obesity... Insulin resistance is showing up FIRST in many young kids, teens, and adults, and THEN the obesity, and the Type 2 Diabetes... I understand your concerns of medications, and overmedications... I have dealt myself with doctors overmedicating me for ONE issue, when they really just missed the BIG picture of my overall health... And that is what these kinds of articles do: Miss the big picture.  We simply just don't understand the full ramifications of everything we are doing right now... to our food, and to our environment.  I, myself, am a child of those kinds of changes: I suffer from Polycystic Ovarian Syndrome (suspected to be caused by pollution, those plastics that leach, and the hormones in cattle, and milk)... and I went from being a thin child, to an obese child, practically overnight... producing massive amounts of insulin, all on my own, for no explainable reason... My thyroid stopped working at an early age, as well... There is NO KNOWN cause for PCOS... And PCOS led me to develop Type 2. So, in essence...
 
1. What we are doing to our environment: Industrial pollution, and climate change, etc.
2. How we are genetically modifying foods.
3. How we use massive pesticides to produce foods.
4. How we are not just modifying foods to yield more produce, but making food that really isn't even food! All that pre-packed stuff...  
5. WE are serving that to our children every day -- in our homes, in our school meal programs, in camps... We are cheaping out on our food, to save a penny or two...
6. How genetics plays into it... because with every generation, DNA changes... sometimes, with a fostering environment, ailments start coming on much, much quicker...  Now even the Surgeon General's Warning has stated that just having ONE cigarette or being exposed to just ONE second hand smoke can change ours or our children's DNA, and mutate it.
 
All those things and much, much more... contribute to people getting almost all the types of Diabetes...  at this point. Either because it messed up your genes, or because it caused an autoimmune attack.
 
Another thing I'd like to point out is that that article has ABSOLUTELY no proof that all those kids are overweight.  Heck, we have one lady in our community, right now, with a child who has Type 2... already needing to take insulin, and who is NOT overweight! Articles like this always seem to choose to want to pass the buck of responsibility around...  and let me tell you, it is a HARD world to feed yourself or your kids proper foods when the school lunch is giving donuts, pizza, soda, and chips to our children, and when employers don't even want to give proper breaks to people to eat... and keep them going 10-14 hour days... And when a Triple Bacon Deluxe costs 99 cents, and broccoli costs $1.50 a lb.  Absolutely, people need to take personal responsibility for their own selves, and their health... and absolutely doctors need to look at the big picture before considering medications... But I REFUSE to get down to the level of calling our struggling children names, such as "drug taking blimps," or pretending a simple diet and exercise is going to solve our huge problems, right now.  Delaying Diabetes for a few more years is NOT preventing it! It will NEVER be preventing it.... And many times even "prevention" is up to fate, and not to us.  My brother, who was a professional athlete, got Diabetes...  And my really heavy, older sister did not.  Hey, it just happens sometimes.  We need to stop blaming and making people feel guilty and awful... because not one case of Diabetes is as simple as just diet and exercise, and you're cured.  Not ONE.  The FDA, the CDC.. the ADA... ALL receive kickbacks from companies, and big pharma... and ALL are puppets to say what they want them to say in the media... Be careful what you read... be careful what you do with the information to treat, or judge your fellow man, or fellow man's children.  We are not stats on a piece of paper...  Just remember that.
