Study Description
Brief Summary:
Continuous glucose monitors may be useful in the treatment of children with Type 1 diabetes mellitus. The purpose of this study was to determine whether two FDA-approved continuous glucose monitors, the Continuous Glucose Monitoring System (CGMS) and the GlucoWatch G2TM Biographer (GW2B), are sufficiently accurate to use in future studies to characterize glucose levels in children.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus Device: Continuous Glucose Monitoring System (CGMS) Device: GlucoWatch G2TM Biographer (GW2B) Phase 4

Detailed Description:

The characterization of glucose levels in healthy children during day and nighttime is critical to the interpretation of glucose levels in diseases such as diabetes. This study was conducted by the DirecNet Study Group to determine whether two FDA-approved continuous glucose monitors are sufficiently accurate.

The study was conducted at five clinical centers and enrolled approximately 20 healthy children (ages 7 to 17 years old) who did not have Type 1 or Type 2 diabetes nor a history of the disease in their immediate families. Each participant was hospitalized for approximately 26 hours to assess the accuracy of the continuous glucose monitors compared with serum glucose determinations.
