The prevalence of impaired awareness of hypoglycemia (IAH) in youth with type 1 diabetes decreased markedly from 33.1% in 2002 to 15.9% in 2024. Concurrently, the rate of severe hypoglycemia (SH) dropped 30-fold over the same period despite improvements in glycemic control. Continuous glucose monitoring (CGM) metrics revealed no significant differences in hypoglycemia exposure between youth with and without IAH in 2024. These findings underscore improved diabetes management and the persistent need for routine IAH screening.
