Use of Continuous Glucose Monitoring Sensors for Type 1 Diabetes Management and its Effect on Glycemic Control

Objectives: To determine the frequency of use of Continuous glucose monitoring (CGM) sensors in individuals with type 1 diabetes mellitus (T1DM). To compare the levels of glycosylated haemoglobin (HbA1c) between CGM users and non-users along with its association with demographics and other variables.   Methodology: In this cross-sectional study, data was collected through non-probability convenience sampling, from all patients with TIDM (from June 2023 to November 2023) enrolled with Meethi Zindagi. After ethical permission, self-structured proforma was filled by patients and parents of patients <12 years having T1DM, under insulin therapy.  Participants were divided into Group 1 (CGM Users) and Group II (CGM non-users).   Results: Out of the total 84 participants, 63% were CGM users. Among CGM users, 60% were male and 59% were children up to 12 years of age. The levels of HbA1C in CGM users were significantly lower compared to non-users. HbA1C levels have a strong negative correlation with the duration of using CGM and the frequency of scanning. Conclusion:  Our data offers initial proof that CGM could serve as an effective instrument across patients of T1DM, to give better glycemic control. The more frequently the CGM sensor is scanned by the user better be glycemic outcomes. The promising role of CGM use for a longer duration helps in effective diabetes management.
