Primary Outcome Measures:
  • Differences in blood glucose [ Time Frame: baseline, 18 months ]
    Changes in A1c and fasting blood glucose over time and between the intervention and control groups.


Secondary Outcome Measures:
  • Impact of lifestyle changes [ Time Frame: baseline, 18 months ]
    Evaluating the impact of lifestyle changes on levels of glycemic control in the control and experimental groups.

  • Changes in Glucose dynamics [ Time Frame: baseline, 18 months ]
    Comparison of intervention and control group on standard measures of glucose dynamics.

  • Differences in blood pressure. [ Time Frame: baseline, 18 months ]
    Objective comparison between the control and experimental group in changes in blood pressure.

  • Differences in lipids. [ Time Frame: baseline, 18 months ]
    Objective comparison between the control group and the experimental group on changes in lipids.

  • Differences in weight [ Time Frame: baseline, 18 months ]
    Objective comparison between the control group and the experimental group on changes in weight.

  • Changes in medication use [ Time Frame: baseline, 18 months ]
    An objective comparison between the control and experimental group on changes in medication use.

Detailed Description:
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.
