Type 1 diabetes, also called "childhood" or "insulin-dependent" diabetes, is on the rise.
Type 2 diabetes, or "adult," diabetes, is also sharply escalating. But the causes for this are easy-to-identify: overconsumption of carbohydrates and resultant weight gain/obesity, inactivity, as well as genetic predisposition. A formerly rare disease is rapidly becoming the scourge of the century, expected to affect 1 in 3 adults within the next several decades.
Type 1 diabetes, on the other hand, generally occurs in young children, not uncommonly age 3 or 4. Type 1 diabetes also shares a genetic basis to some degree. But the genetic predisposition should be a constant. Obviously, lifestyle issues cannot be blamed in young children.
Then why would type 1 diabetes be on the rise?
For instance, this study by
Vehik et al from the University of Colorado documents the approximate 3% per year increase in incidence in children with type 1 diabetes between 1978 and 2004:

This is no small matter. Just ask any parent of a child diagnosed with type 1 diabetes who, after recovering from hearing the devastating diagnosis, then has to stick her child's fingers to check glucose several times per day, mind carefully what he or she eats or doesn't eat, watch carefully for signs of life-threatening hypoglycemic episodes, not to mention worry about her child's long-term health. Type 1 diabetes is a life-changing diagnosis for both child and parents.
Comment: While it is true that being morbidly obese or severely underweight can shorten a lifespan, the jury properly should still be out on smoking. In fact, if Dr. Ioannidis' principles were applied to smoking studies, it's likely that 99% of them would have to be thrown out.
