The dramatic increase in newly diagnosed cases of type 2 diabetes (T2D) has developed into a major public health concern worldwide. Conversely, several clinical studies have demonstrated that preventive efforts can significantly reduce the risk of developing diabetes. There is a clear consensus that action is needed to develop targeted community-based prevention programs and strategies for T2D. Currently, numerous prevention management concepts that can be implemented into clinical practice exist in various countries. Finland is the pioneer country in implementing community-wide diabetes prevention programs. Nevertheless, population-based nationwide strategies are still lacking in virtually all countries. We report on intervention strategies to prevent T2D in people with increased diabetes risk, as well as strategies on how to implement diabetes prevention programs into the real world of public health or clinical care. The implementation of managed prevention concepts will realistically help to improve the ability to prevent T2D in the public health framework.
