Association Between the Implementation of Continuous Glucose Monitoring and Changes in Dietary Behavior in Insulin-Treated Patients With Diabetes Regardless of Diabetes Type

A total of 42 participants were included. The mean age was 67 ± 13 years, and the median duration of diabetes was 11 (8.0-16.0) years. Thirty-one participants used CGM, whereas 11 did not. At baseline, the mean carbohydrate intake as a percentage of total calories was 51% in the CGM group and 52% in the non-CGM group. After three months, these values were 50% and 56%, respectively. However, difference-in-differences analysis revealed no significant difference between the groups (p = 0.295). Conclusion: CGM implementation was not significantly associated with changes in dietary behavior among insulin-using patients with diabetes. These findings indicate that CGM alone is insufficient, necessitating complementary strategies to promote dietary behavioral modification in this population.
