Insulin-dependent diabetes is rare in the newborn but increases in frequency after 9 months of age.1 The majority of studies have shown young childhood (4 to 5 years of age) and preadolescence (10 to 14 years of age) to be the most common ages at onset. However, several studies have noted smaller peaks of increased incidence in children younger than 5 years of age.2-5 The number of such children with insulin-dependent diabetes may be increasing.
