Historically, type 1 diabetes mellitus has been associated with large reductions in life expectancy. Livingstone and colleagues assessed life expectancy in a contemporary cohort of 24 691 Scottish patients with type 1 diabetes and found that compared with the general population, subsequent life expectancy at age 20 years for patients with diabetes was approximately 11 years less for men and 13 years less for women. In an Editorial, Katz and Laffel discuss prevention of diabetes complications to improve patient survival.
