8-OR: Short-Term Continuous Glucose Monitoring Reveals Insights and Promotes Behavioral Awareness in People with Non-Insulin-Treated Type 2 Diabetes, Even after Minimal Instructions

Introduction and Objective: CGM has shown promise as a valuable tool for learning and managing blood glucose levels in persons with non-insulin-treated Type 2 Diabetes (PwT2D). This study investigated the insights PwT2D gain regarding the influence of lifestyle factors on blood glucose levels over a two-week period of CGM usage, with minimal instruction and support. Methods: As a walk-in setup in 20 cities in Denmark, a single CGM device (max. 14 days) was provided to PwT2D not on insulin therapy. Participants received minimal guidance during device installation and completed a baseline questionnaire onsite. Follow-up surveys were sent via email after two weeks and three months. Results: Of the individuals enrolled,724 completed the second questionnaire after two weeks. Of these, 80% found the CGM highly useful and informative. Compared to participants with a diabetes duration over five years, participants with a diabetes duration of less than five years engaged in more daily scans (80% vs. 71%) and reported greater insights into how blood glucose levels were affected by food items (88% vs. 78%), portion sizes (80% vs. 60%), and physical activity (65% vs. 55%). Education level had no significant impact on knowledge acquisition. At the three-month follow-up, half of the participants reported maintaining behavioral changes based on their two-week CGM experience Conclusion: The findings highlight that even brief CGM usage with minimal instruction can provide PwT2D with valuable, personalized insights into how lifestyle factors influence blood glucose levels. These insights may encourage long-term behavioral changes, potentially leading to improved glycemic control. Notably, diabetes duration significantly influences the depth of insights gained, while education level does not appear to impact knowledge acquisition. E. Munch Nielsen: None. A.K.
