Why Type 1 Diabetes Goes Undiagnosed in Low-Income Countries—and What Could Help

Type 1 diabetes affects approximately 1.2 million children and adolescents across the globe. But where a child lives shapes how quickly they get diagnosed—and that timing matters enormously. In low- and middle-income countries (LMICs), delayed diagnosis is a major driver of serious illness and death. A new systematic review, following rigorous research guidelines, examined nine studies to understand what stands in the way of early detection in these settings.

The research found that barriers to early detection cluster in three critical areas. First, how diagnostic services are organized and delivered is often a bottleneck. Second, gaps in the health workforce—whether due to training, staffing, or resources—slow diagnosis. Third, access to the diagnostic tests themselves is limited. These aren't isolated problems; they work together to delay the moment when a child gets confirmed diagnosis and starts treatment.

Currently, early detection in LMICs tends to be passive—meaning it happens only when a child shows up sick at a hospital, rather than through active screening. Worse, detection is concentrated in higher-level facilities like regional hospitals, leaving primary care clinics largely out of the picture. Primary care is where most families go first; integrating Type 1 diabetes screening into those settings could catch more cases earlier.

Even when a child is diagnosed, fragmented referral pathways mean the journey to actual care is often unclear. Studies showed weak connections between clinics and gaps in getting children linked to ongoing treatment. These broken links mean a diagnosis, when it finally comes, doesn't automatically lead to the support and insulin a child needs.

This review highlights that improving early detection isn't about a single solution. Instead, health systems in LMICs need coordinated improvements: better provider training, more access to diagnostic tools, integration of screening into primary care, and stronger referral pathways that connect diagnosis to treatment. Understanding these barriers is the first step toward building systems that catch Type 1 diabetes sooner and keep children healthy.
