Enhance Lifestyle Awareness in T2D with brief use of CGM.

<h2 id="Objective">Objective:</h2><p>To evaluate the usefulness of short-term continuous glucose monitoring (CGM}, in providing insights into lifestyle-related blood glucose fluctuations among individuals with type 2 diabetes (T2D} not treated with insulin.</p><h2 id="Methods">Methods:</h2><ul><li>Observational study with non-insulin-treated T2D across 20 cities in Denmark were enrolled.</li><li>Individuals received a CGM device in a walk-in setting with minimal installation guidance and were instructed to use it for up to 14 days.</li><li>Baseline questionnaires were completed at the time of device placement, followed by online surveys at 2 weeks and 3 months post-use to assess insights gained and behavioral changes.</li><li>A total of 724 participants completed the 2-weekfollow-up questionnaire.</li></ul><h2 id="Results">Results:</h2><ul><li><strong>Perceived usefulness: </strong>80% of participants found CGM highly informative forT2D management.</li><li><strong>Lifestyle insights:</strong> Participants with &lt;5 years as compared to &gt;5 years of diabetes duration reported greater insights on glucose levels related to,<ul><li>Effects of food (88%vs. 78%}</li><li>Portion sizes (80% vs. 60%}</li><li>Physical activity (65% vs. 55%}</li></ul></li><li><strong>Engagement:</strong> The shorter-duration group also performed more frequent daily scans (80%vs. 71%}.</li><li><strong>Equity in learning:</strong> Educational level did not significantly affect the extent of insights gained.</li><li>At 3-month follow-up, 50% of participants reported sustaining behavioral changes initiated during the CGM use period.</li></ul><h2 id="Conclusion">Conclusion</h2><ul><li>Short-term CGM use in non-insulin-treated T2D patients provided meaningful, personalized insights into lifestyle factors affecting glycemic control, particularly in individuals with a shorter diabetes duration.</li><li>These insights contributed to sustained behavioral changes in half of the participants, supporting the potential role of short-term CGM as an educational and motivational tool in early T2D management.</li></ul>
