Effectiveness of a Personalized Smartphone-assisted Coaching System to Improve Glucose Homeostasis in Adults with Prediabetes: Rationale and Study Protocol (Sweetch app)


The overall study will consist of two parts conducted in tandem: This Pilot Study is a 3-month pilot RCT study to test the feasibility of the Sweetch app in combination with a digital body weight scale (DBWS), with both groups receiving usual care for prediabetes.

This research is being done to see how well a mobile phone application (app) in combination with a digital body weight scale (DBWS) helps people with prediabetes monitor and manage their activity, nutrition, weight, and other measures to improve their health. Cardiovascular complications associated with type 2 diabetes begin at the prediabetes stage, and more than half of individuals with prediabetes will eventually develop diabetes.
