Abstract: OBJECTIVE Automated insulin delivery (AID) systems improve glycemic outcomes in youth with type 1 diabetes and are now the recommended mode of insulin delivery. Previous studies highlighted racial disparities in the use of continuous glucose monitoring and insulin pump therapy. The purpose of this study was to evaluate the use of AID systems and A1C outcomes in youth with type 1 diabetes by race. RESEARCH DESIGN AND METHODS This was a single-center cross-sectional study. We included youth and young adults with type 1 diabetes aged 2–21 years who had at least two clinic visits between December 2022 and December 2023. Demographics, diabetes device use, and A1C data were gathered from chart review, based on the latest office visit records available in the electronic medical record system for 2023. RESULTS Out of 668 youth aged 3.1–19.9 years with type 1 diabetes, 435 (65%) were AID users. The prevalence of AID use was 70% (341 of 483) in White youth compared with 47% (60 of 129) among Black youth and 62% (34 of 55) among youth of other racial groups (P <0.001). Black youth using AID achieved significantly lower A1C levels (median 8%, interquartile range [IQR] 7.5–8.8%) compared with Black youth who did not use an AID system (median 9.6%, IQR 8.1–11.6%) (P <0.001). CONCLUSION These findings support the persistence of racial disparities in diabetes technology utilization.
