Introduction and Objective: Several GLP-1 drugs are FDA approved for type 2 diabetes (T2D) or obesity. The 2024 ADA standards of care highlight that for individuals with T2D and obesity/overweight, GLP-1 therapy is preferred. While many adults with T1D are overweight/obese, GLP-1 use in this population is not well characterized. Data from the T1D Exchange Online Registry was leveraged to assess self-reported GLP-1 use by demographic and clinical characteristics.
Methods: Registry participants complete questionnaires annually. This analysis includes T1D adults who completed a questionnaire in 2023.
Results: Among 8,053 adults, 470 (5.8%) reported using a GLP-1, % using GLP-1 by characteristics are shown in the Table. Median HbA1c was similar in those using (6.6%) and not using (6.5%) GLP-1. GLP-1 use was more common in adults with obesity and cardiovascular disease and less common among those with severe hypoglycemia. Among those with known GLP-1 type (n=109), 67% used semaglutide, 16% tirzepatide, 10% dulaglutide, 6% liraglutide and 1% exenatide.
Conclusion: GLP-1 use in this cohort of adults with T1D is low despite increasing prevalence of obesity. With increased focus on treatment of obesity, trends of GLP-1 use in those with T1D may change over time. Considering the benefits of these agents, further prospective research focused on this population is needed.
