The Natural History of Prediabetes and Cardiovascular Disease in the Pediatric Population

The prevalence and incidence of prediabetes in children and youth continue to increase in parallel with the obesity epidemic. While prediabetes is defined by elevated HbA1c and/or impaired glucose tolerance (IGT) and/or impaired fasting glucose (IFG), the risk of clinical disease is a continuum. Individuals with prediabetes are at a higher risk of developing youth-onset type 2 diabetes, which is considered a more aggressive form of the disease. This condition is associated with increased cardiovascular and metabolic risks and leads to an earlier onset of complications compared to adults with type 2 diabetes. Additionally, significant damage to beta cells may occur even before dysglycemia develops. Recent data indicate that mortality rates are higher in youths with type 2 diabetes compared to those with type 1 diabetes. Childhood prediabetes and cardiovascular complications associated with it are a significant health concern. This review provides the latest insights into this complex issue. We will present an overview of pathophysiology, screening methods, and therapeutic options to prevent the progression from prediabetes to type 2 diabetes in children. In summary, it is crucial to identify prediabetes in children, as this underscores the importance of appropriate screening and timely intervention.
