Turnaround Health offers the only completely automated, totally virtual diabetes prevention program with clinical trial evidence showing changes in hemoglobin A1C and fasting glucose. Alive-PD ("prevent diabetes") is a fully-automated algorithm-driven intervention for people at risk of developing diabetes. This includes persons with obesity or metabolic syndrome in addition to those with pre-diabetes. Alive-PD provides a program of regular contact, including individually-tailored weekly goal-setting and other activities delivered via web and email, supplemented by automated interactive voice response (IVR) phone calls and a supportive smartphone application for Android and iPhone. The curriculum is based on established principles derived from several bodies of behavior change research and is supported by clinical trials demonstrating effectiveness.
