According to a recent article in the March 2012 issue of the Journal of the American Geriatrics Society, Temple researcher Adam Davey has found centenarians diagnosed with diabetes in their 80s living 20 or more years with the condition. The study tested 244 older adults, ages 98 to 108, in 44 counties. It found that 12.5 percent — or 1 in 8 — of the group had type 2 diabetes.
