Pima Indians who developed type 2 diabetes before they were 20 years old later developed kidney disease at the same rate as those who got type 2 as adults.
The rate of retinopathy, however, was not as great among those with youth-onset type 2.
Researchers from the National Institute of Diabetes, Digestive and Kidney Diseases, National Institutes of Health, studied the rate of kidney and eye disease in 2,508 Pima Indians, who were followed for 25 years. Of these subjects, 178 were diagnosed with type 2 before age 20; 1,359 were diagnosed between ages 20 and 39; and 971 were diagnosed between ages 40 and 59.
