Introduction: Young adults (YA) with type 1 diabetes (T1D) are at risk of poor glycemic control. Use of continuous glucose monitoring (CGM) has been shown to improve glucose control. However, real-world data on the impact of CGM use on glucose control in YA is limited.

Methods: We analyzed data from electronic medical records collected across 2018 from a tertiary adult clinic of YA patients age 18- 30 yrs with T1D. A1C and insulin administration methods defined as sliding scale (SS), multiple daily injection while carbohydrate counting (MDI), or via pump therapy (Pump) were collected along with CGM use.

Results: Data from 891 patients (mean age 26±3, T1D duration 12±7 years, 52% female, average A1C 7.9%±1.5) were analyzed. Twelve % (n= 110) were on SS; 37% (n=331) on MDI, and 51% (n= 450) on pump therapy; mean age of all 3 groups was 26 ± 3yrs. Use of CGM was recorded in 32% of patients on SS, while use of CGM was recorded in 46% and 66% of patients using MDI and pump, respectively.

A1C differed between CGM users and non-users in each subgroup.

Conclusion: With increasing complexity of insulin regimen, CGM use rises. However, independent of insulin administration method, CGM use was associated with lower A1C. These findings highlight the potential benefit of CGM use, in YA with T1D in adult clinic settings.
