Continuous Glucose Monitoring for Prediabetes

This study is looking at how continuous glucose monitoring (CGM) combined with health education videos on a smartphone can help people with prediabetes manage their blood sugar. The goal is to prevent prediabetes from turning into type 2 diabetes. You might be able to join if you are 35 or older, have prediabetes (diagnosed by a blood test called A1C% or fasting glucose, or a high CDC risk score), and are willing to wear a CGM sensor. The study will measure your glucose levels for up to 20 days to see if getting feedback from the CGM and educational videos helps improve your blood sugar control. The study plans to enroll 50 participants and its current status is unclear.

Study design
This is an interventional study that plans to enroll 50 adults. Participants will wear a CGM device for 20 days, with glucose data masked for the first 10 days and unmasked for the next 10 days.
What's involved
You would wear a CGM sensor on your arm for 20 days. During the last 10 days, you would receive daily health education videos on your smartphone.
Compensation
Not stated in the trial record.
Follow-up
Glucose levels will be measured for a maximum of 20 days of continuous wear.
