Using data from about 600 000 adults over 26 years, researchers have concluded that the lifetime risk of developing type 2 diabetes for the average American 20-year-old rose from 20% for men and 27% for women in 1985, to 40% for men and 39% for women in 2000. The largest increases were in Hispanic men and women, and non-Hispanic black women, for whom lifetime risk now exceeds 50%.
