From Pasadena, California, USA:
How many children with diabetes are diagnosed before age 3? What percent of children with diabetes are autistic?
It is difficult to answer your first question precisely because it is now recognised that there are many different forms of diabetes in childhood and that the incidence of all of these varies with geographical location. In the US the incidence of the commonest form of Diabetes which is Type 1A or autoimmune diabetes is now about 18.0 per 100,000 per year up to about age 18. The incidence peaks around eight years and early in puberty. Moreover as diagnostic methods improve it is becoming possible to detect most of those children who are going to get diabetes in the preclinical phase by the second year in life and before the conventional symptoms and signs of clinical diabetes appear.
In answer to your second question, I know of no studies the show any bias in diabetic children toward autism.
