The protocol is a prospective, non-blinded, randomized controlled study in persons with newly diagnosed pre-diabetes comparing the effects of real-time continuous glucose monitoring (RT-CGM) combined with diet and lifestyle education to those who have diet and lifestyle education alone. During a wash-in phase both groups will wear a masked CGM for 1 week at baseline and again after 12 weeks. Those randomized to the RT-CGM will wear it for 4 cycles of 2 week on/1 week off over the next 12 weeks. Both groups will follow-up with their primary care providers as clinically indicated over the next year with quarterly measurements of blood pressure, weight, and BMI. At the end of this period, they will wear a masked CGM for 1 week.
This study will investigate whether real-time continuous glucose monitoring can be used as a tool for behavior change in people with pre-diabetes.
