Early racial/ethnic disparities in continuous glucose monitor use in pediatric type 1 diabetes.

Racial-ethnic disparities in technology use have been described in children with type 1 diabetes (T1D). It is not known if these emerge early in disease management. This single-center retrospective study examined disparities in continuous glucose monitor (CGM) initiation and durability in the first-year following diagnosis of T1D in children. Of 345 eligible children, 46% started CGM within their first-year. In non-Hispanic white (NHW) children, 51% started using CGM vs 28% of non-Hispanic black (NHB) children (p=0.006). After stratifying by commercial/government insurance, a proxy for socioeconomic status, this difference persisted among those with commercial insurance. One-year post CGM initiation, 96% (125/130) of NHW children were using CGM vs 73% (11/15) of NHB children (p=0.003). Disparities in CGM use emerge early in care of children with T1D, with lower rates of initiation and sustained use of CGM in NHB children. Strategies addressing causes of these disparities should begin early in T1D management.
