Objective: To evaluate long-term
glycemic outcomes of CGM initiation within the first year of type 1 diabetes.
<p>Research Design and
Methods: 396 patients with type 1 diabetes were divided into three groups; 1)
CGM [CGM use within one year of diabetes and continued through the study], 2)
no-CGM [no CGM use throughout the study], 3) new-CGM [CGM use after 3 years of diabetes]
and were followed up to 7-years. </p>
<p>Results: A1c was
significantly lower in CGM compared to no-CGM group throughout 7 years of follow-up
[LS mean A1cs (%): 6-month 7.3 vs 8.1, 1-year 7.4 vs 8.6, 2-year 7.7 vs 9.1,
3-year 7.6 vs 9.3, 4-year 7.4 vs 9.6, 5-year 7.6 vs 9.7, 6-year 7.5 vs 10.0 and
7-year 7.6 vs 9.8, all p<0.001] adjusting for age at diagnosis, sex, and
insulin delivery method. </p>
<p>Conclusion: CGM initiation
within first year of type 1 diabetes results in long-term improvement in
A1c. </p>
