The transition from pediatric to adult care is a critical period for young people with type 1 diabetes. In Djibouti, the Young Diabetic Center has implemented a structured therapeutic education program to support this transition. A one-year prospective study of 100 patients aged 16 to 21 evaluated the impact of this process on glycemic control (HbA1c), autonomy, and satisfaction among young adults. The results show a modest but significant improvement in HbA1c after 12 months, despite the persistence of imbalance in nearly half of the participants. Female gender, low autonomy, and insufficient medical follow-up appear to be vulnerability factors. This experience highlights the importance of a coordinated, multidisciplinary, and patient-centered transition.
