Diagnosis Rate in Central Sub-Saharan Africa: less than 20%
Identify Undiagnosed Diabetes to Prevent Complications
In 2023, an estimated 44% of people aged 15 and older with diabetes are unaware of their condition. Underdiagnosis was greatest among young adults -- despite facing higher risks for long-term complications.
Among those who were diagnosed, 91% were on some form of pharmacological treatment. However, of those receiving treatment, only 42% had their blood sugar levels managed optimally. This translates to just 21% of all people with diabetes globally having their condition under optimal management.
Despite improvements over two decades, the research also found substantial regional diagnosis and treatment disparities, particularly in low- and middle-income countries. High-income North America had the highest rates of diagnosis, while high-income Asia Pacific showed the highest rates of treatment among diagnosed individuals. Southern Latin America had the highest rates of optimal blood sugar management among those treated. In contrast, Central sub-Saharan Africa faced the largest gaps in diagnosis, with less than 20% of people with diabetes being aware of their condition.
"By 2050, 1.3 billion people are expected to be living with diabetes, and if nearly half don't know they have a serious and potentially deadly health condition, it could easily become a silent epidemic," said Lauryn Stafford, first author and researcher at IHME.
Given the pace at which cases are rapidly rising, the research underscores the urgent need for investment in screening programs for younger populations and access to medications and glucose-monitoring tools, especially in underserved regions. In 2022, the WHO set a target to have 80% of people with diabetes clinically diagnosed by 2030.

Clinical Perspective — Dr. Sneha Rao, Pediatrics
Workflow: As I see patients, I'm now more likely to screen for diabetes in young adults, given that underdiagnosis is greatest in this group. With 44% of people aged 15 and older with diabetes unaware of their condition, I'd routinely ask about symptoms and risk factors. This change in my routine is crucial, especially since it can help identify cases early on.
Economics: The article doesn't address cost directly, but it highlights the need for investment in screening programs and access to medications, particularly in low- and middle-income countries. I'm concerned about the potential economic burden of undiagnosed diabetes, and I hope that future research will provide more insight into the cost-effectiveness of these interventions.
Patient Outcomes: Only 21% of all people with diabetes globally have their condition under optimal management, which is alarming. I'm focused on improving blood sugar management for my patients, knowing that optimal control can significantly reduce the risk of long-term complications. The WHO's target to have 80% of people with diabetes clinically diagnosed by 2030 is a crucial step towards better patient outcomes.
