Research on diabetes distress in continuous glucose monitor (CGM) users with T1D is divided. Some studies suggest CGM users experience less distress compared to non-users, whereas other studies find no differences in distress. While research shows higher distress is related to higher HbA1c, more work is needed to understand how distress is related to CGM metrics. Thus, we recruited adult CGM users with T1D (n = 199) from the T1D Exchange Registry to complete an online survey about diabetes characteristics and a screener of diabetes distress (DDS-2). CGM metrics (defined in Table 1) were computed from CGM data within 12 months prior to survey completion. Participants were grouped into lower (DDS-2 < 3, n = 120) or higher (DDS-2 ≥ 3, n = 79) diabetes distress. We used Welch’s t-tests to compare mean differences in blood glucose (BG) experiences and CGM metrics between participants with lower and higher diabetes distress. As shown in Table 1, participants with higher diabetes distress reported higher HbA1c, and - via CGM metrics - experienced more time in higher BG ranges and less time within standard target ranges, had higher blood glucose variability, and had higher GMI compared to those with lower distress. Associations between distress and CGM metrics replicated in a MANCOVA after adjusting for duration of T1D. Our results suggest, in CGM users, higher perceived diabetes distress is associated with more time in hyperglycemia. Disclosure C. S. Kelly: None. H. Nguyen: None. K. S. M. Chapman: None. E. M.
