Poor glycemic control is a risk factor for many diabetes-related complications, but global real-world data on diabetes management in adults with T1D is limited. SAGE was a multinational, observational, cross-sectional study to describe glycemic control of participants aged ≥26 years with T1D for ≥1 year.

Of 3858 participants from 17 countries, 54.6% were female, with mean (standard deviation [SD]) age 47.4 (14.0) years, T1D duration 20.7 (12.6) years, and age at T1D onset 26.7 (14.4) years. Childhood-onset T1D was most common (48%) in the 26-44 years age group. Mean (SD) HbA1c was 7.95 (1.42) % (63.4 [15.6] mmol/mol), and similar across predefined age groups (Table). Only 20.9% of participants reached their individualized HbA1c target. Prevalence of microvascular complications was 36-63%, increasing with age and duration of diabetes. Incidence of diabetic ketoacidosis was similar in all age groups and consistent with previous reports.

SAGE shows that the prevalence of microvascular complications remains high, affecting over half of the study population aged ≥65 years, and is more prevalent in those with a longer duration of diabetes.
