Rising rates of type 1 diabetes may be primarily confined to children and teenagers, a British study shows (Diabetologia, vol. 43, suppl. 1, p. A27).
Presented at last year’s European Associations for the Study of Diabetes conference in Jerusalem, the study found peak incidence of type 1 at age 14 in males and females, but also saw rates of incidence dropping in the years that followed.
The test subjects were observed over the course of around seven years in the county of West Yorkshire. All of the study’s 885 subjects were between the ages of 0 and 29 years of age.
The 0-to 14-year-old group showed a 3.3 percent average annual increase in incidence of diagnosis and the 15- to 29-year-old group showed a corresponding decrease of 0.26 percent. In males the rate of incidence started to rise again after age 20, but in females it continued to decline.
The study’s authors conclude that children and adults show very different rates in the incidence of type 1 diabetes, with the peak rate occurring in young teenagers. They say this suggests type 1 in children may have different causes and methods of operation than it does in adults.
