Finnish Diabetes Prevention Study (2001)
A foundational Finnish trial showed that intensive lifestyle counseling on diet and exercise cut type 2 diabetes incidence by 58% in adults with impaired glucose tolerance.
The protective effect persisted for years after the counseling period ended.
It became the model for translating lifestyle trials into reimbursed diabetes prevention programs, including the US National Diabetes Prevention Program.
It shows the adoption path a dementia lifestyle program might follow, from randomized trial to standard clinical care.
