Résumé
Individuals with type 1 diabetes of minoritized race-ethnicities and low-socioeconomic status (SES) do not access nor use automated insulin delivery (AID) technology at equal rates compared to their non-Hispanic White (NHW) and high SES counterparts. Using four AID trials (n=292), we ran linear mixed models to compare glycemic outcomes using race/ethnicity, education, and income. These trials overrepresented NHW (83%), high-income (91%), and highly educated (86%) populations. By education, participants with <bachelor's degree had worse baseline glycemic control than those with ≥bachelor's degree as per HbA1c: 7.83% vs. 7.25% (p<0.001), time-in-range: 50.1% vs. 61.2% (p<0.001), and time >180 mg/dL: 46.2% vs. 34.5% (p<0.001). These differences disappeared following AID use. By race/ethnicity and income groups, there were no differences in baseline glycemic control. While baseline glycemic control tended to be worse for underrepresented populations, AID glycemic efficacy was approximately equivalent. These results suggest improving accessibility to AID could equalize glycemic outcome disparities.
