Kahkoska AR, Pokaprakarn T, Alexander GR, et al. - A part of but not all disparities in glycemic control between non-White and White youth and young adults (YYA) were explained by mathematically modeling an equalized distribution of type 1 diabetes (T1D) self-management tools and technology. This highlights the complexity of race and ethnicity-based health inequity.

• Disparities in population-level glycemic control and occurrence of diabetes complications were estimated, given a theoretical scenario wherein non-White YYA suffering from T1D undergo and follow an equal distribution of diabetes treatment regimens as non-Hispanic White YYA.

• Using longitudinal data, this study involved 978 YYA, 47.5% were female and 77.5% were non-Hispanic White, with a mean age of 12.8 ± 2.4 years at diagnosis.

• Mean hemoglobin A _1c across visits reduced by 0.33% within the non-White subgroup if they received the distribution of diabetes treatment regimens of the White subgroup, accounting for ∼35% of the estimated disparity between the two subgroups.

• A lower risk of diabetic retinopathy, diabetic kidney disease, and peripheral neuropathy was noted in the non-White subgroup if they received the White youth treatment regimen distribution, although the low proportion of YYA who experienced complications limited statistical power for risk estimations.
