Know how many American kids actually DO have T2d?
The short answer is, nobody knows for sure, because it’s so rare nobody can get exact numbers.
But…extrapolating from data on the ADA Web site (not a fat-friendly organization, mind you, so they have no motivation to fudge the numbers in our favor), the number would seem to be…drum roll please…about 30,000 or 40,000 people younger than 20 diagnosed with T2d in the U.S. Yes, that’s in the entire country. Yes, that’s out of about 83 million people under 20 years old in America. I am not kidding. We really ARE talking about a number THAT tiny, and the only time they had a percentage-population increase in the 22 years they’ve been tracking it (and no, they didn’t track it at all before that) was when they lowered the diagnostic criteria from fasting blood sugar > 140 to FBS > 126. (Newsflash: Broadening the diagnostic criteria and actually testing people for it means more people diagnosed. I’m autistic, I know this quite well.)
How’d I get my numbers? Simple. The ADA says:
186,300, or 0.22% of all people in this age group have diabetes
About one in every 400 to 600 children and adolescents has type 1 diabetes
Therefore, we can surmise that about 70% of all diabetes cases in people < 20 years old in America are type 1. The rest are a combination of type 2, MODY (maturity-onset diabetes of youth, which some consider a subset of type 2 and some consider a separate condition), gestational, and secondary (due to pancreatic injury or some other systemic illness attacking the pancreas). Therefore, the type 2 figure is no more than 50,000 at the very most, and probably considerably less than that.
And of those 30,000 or 40,000 kids, give or take, what percentage have first or second-degree relatives with the disease? About 85 percent. That’s according to the paper that initially identified the T2d youth trend back in 1996; the entire paper isn’t available online, unfortunately. (Even so, the abstract says the link with first-degree relatives alone is around 65%.) And if you like medical nerdery, this paper from Endocrine Review talks about the polygenetic nature of T2d, confirming that this is about way, way more than the fourth-grade-level assumption of “eat like a pig, get fat, give yourself diabetes.” (Hat tip to Sandy/JFS for both papers.)
Oh, and even Dr. Francine Ratner Kaufman, whose infamous “New Epidemic” paper (which said T2d is “responsible for 8-45% of new cases of diabetes, depending on geographic location,” which some people — including our first lady? — have interpreted as “8-45% of kids have T2d”!), admitted the overwhelming genetic link in her paper. So there.
And that’s not even taking into consideration that kids have fluctuating insulin levels as they are growing and could possibly be misdiagnosed with T2d because of that, especially if they’re fat. (Not to mention that this is a disease that disproportionately affects poor nonwhite children and teens. But of course, that couldn’t possibly have anything to do with increased genetic propensity, or with their stress levels being off the frigging charts and their health-care and food availability and neighborhood safety being total garbage compared to their whiter and/or more affluent counterparts, now could it? Nah, we just have to get them all to quit eating fries because fries are the root of all evil, and fat kids who eat them — or hell, even the ones who don’t — deserve to be reminded nonstop that they’re the reason America can’t have nice things.)
So Mrs. Obama’s panic-button projections (which seem to have been gleaned from a decade-long game of Telephone rather than actual facts) lead her to believe that “in a generation” (20 years from now?), we’re going to go from 30,000 kids, almost all of whom have a strong genetic link to T2d, to almost 30 million kids with T2d, almost none of whom do? How??? How is that even remotely possible?
Oh, I forgot. They’ll lower the diagnostic criteria again to FBS > 110, then 100, then 90, then 80…
