The impact of learning disabilities on control, management, and outcomes of type 2 diabetes mellitus in the UK: an observational cohort study using the Clinical Practice Research Datalink

Individuals with learning disabilities had better glycemic control but shorter time to insulin initiation. This may be related to more frequent diabetes monitoring, or faster advancing T2DM requiring quicker treatment intensification. Despite having similar risks of vascular complications, people with learning disabilities were at higher risk of death. Future research into the mechanisms behind this could help reduce health disparities for people with T2DM and learning disabilities.
