The world's type 1 diabetes burden is growing. A new model projects global T1D cases will climb from 530,024 to 605,058 per year by 2049, with the number of people living with the disease reaching 12.2 million. Low-income countries are expected to see the sharpest relative rise, spotlighting a critical gap in insulin access and care quality.
A new modeling study presented at the European Association for the Study of Diabetes (EASD) annual meeting paints a sobering picture of the global type 1 diabetes (T1D) trajectory. Using the DIAMOND-T1D model — which draws on incidence data, country demographics, and population survival statistics — researchers project that annual new T1D cases will grow from 530,024 in 2025 to 605,058 by 2049, while the total number of people living with T1D will jump from 9.4 to 12.2 million.
While most people with T1D currently live in high- and middle-income countries, the largest relative increase in prevalence is expected in low-income countries — where children are also disproportionately affected by T1D-related deaths.
Why it matters: The growing T1D burden — especially in resource-limited settings — underscores an urgent need to expand insulin access and improve care quality globally. Without targeted intervention, the mortality gap between wealthy and low-income nations will only widen.
