Authors' conclusion
In 2024, one in nine adults worldwide was living with diabetes. The number of adults with diabetes in 2024 exceeded 500 million and is projected to rise to close to 900 million by 2050. As the diabetes epidemic has continued unchecked since the turn of the millennium, stronger efforts are needed to slow its progression, with strategies tailored appropriately across countries and population groups.
