Introduction and Objective: Continuous glucose monitoring (CGM) has been associated with improved glycemic outcomes in older patients with Diabetes Mellitus (DM). Older patients may face barriers to use including challenges with technology. We are not aware of any comparison between older and younger adults. We studied if older age is associated with less favorable CGM metrics.Methods: We collected data from a CGM web-based interface, including patients with DM who had sensors active ≥ 70% of time. A total of 579 patients < 65 years (mean age=49.4 (SD=11.4) years) and 331 patients ≥ 65 years (mean age = 72.6 (SD=6.31) years) met inclusion criteria. Two sample t-tests compared % time in range, % time above range, and % time below range between the two age groups.Results: Patients ≥ 65 years showed better glycemic control when compared to patients < 65 years for % time in range and % time above range. Data was further stratified by decade of age. An ANOVA analysis showed an effect in % time in range (F(6, 903) = 3.02, p = 0.006, Eta2 = 0.02) between groups. A Tukey’s HSD post-hoc test revealed patients < 30 years and patients in their 70’s were the solitary paired age group with a statistically significant difference (p = 0.014).Conclusion: These results indicate that older patients have superior metrics when using CGM devices, when compared to younger patients. Age alone is not a predictor for worse CGM outcomes.
