Abstract
Diabetes mellitus (DM) in children represents a significant and growing public health challenge globally. While Type 1 Diabetes (T1D) remains the most prevalent form in childhood, the incidence of Type 2 Diabetes (T2D) and other forms is rising alarmingly, paralleling trends in childhood obesity. This article provides a comprehensive review of pediatric diabetes, adhering to the IMRAD structure. It explores the epidemiology, pathophysiology, and distinct clinical presentations of the main diabetes types affecting children. A detailed analysis of current management paradigms is presented, emphasizing the importance of intensive, family- centered glycemic control to prevent acute and chronic complications. The article further discusses the profound psychosocial impact of a chronic disease diagnosis in childhood and adolescence. Finally, it examines emerging technologies and therapies, identifying critical gaps in research and public policy. The conclusion synthesizes the state of the field, underscoring the necessity for early detection, multidisciplinary care, and sustained research to improve long-term outcomes for children living with diabetes.
Introduction
Diabetes mellitus is a group of metabolic disorders characterized by chronic hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Its manifestation in children and adolescents presents unique clinical, developmental, and psychosocial challenges distinct from adult-onset disease. Historically, diabetes diagnosed in childhood was al- most exclusively autoimmune Type 1 diabetes. However, the 21st century has witnessed a dramatic epidemiological shift, with a marked increase in cases of Type 2 diabetes, mono- genic diabetes (e.g., MODY), and other forms in pediatric populations.
The global burden is substantial. According to the International Diabetes Federation (IDF), approximately 1.2 million children and adolescents under 20 live with Type 1 diabetes, with around 164,000 new cases diagnosed annually. The incidence of T1D is increasing by 3-4% per year in many countries, particularly in younger children. Con- currently, the rise in childhood obesity has precipitated an epidemic of T2D in youth, a disease once termed adult-onset. In the United States, the SEARCH for Diabetes in Youth study found that from 2002 to 2018, the estimated prevalence of T1D increased by 45.1% and of T2D by an alarming 95.3%.
This epidemiological transition complicates diagnosis and management. Differentiating between T1D, T2D, and monogenic diabetes is crucial for appropriate therapy but can be challenging due to overlapping phenotypes, particularly in obese adolescents. Misdiagnosis leads to suboptimal treatment and worse outcomes. Furthermore, the management of a lifelong chronic condition during critical periods of physical, cognitive, and emotional development requires a tailored, multidisciplinary approach.
The primary aims of this article are to: 1) delineate the classification, etiology, and clinical presentation of diabetes in children; 2) review evidence-based management strategies from diagnosis to long-term care; 3) analyze the acute and chronic complications associated with pediatric diabetes; and 4) explore the psychosocial dimensions and future directions in research and care. This synthesis aims to provide a foundational resource for clinicians, researchers, and students involved in pediatric diabetology.
Methods
This article is based on a comprehensive narrative review of the scientific literature. A systematic search was conducted using major electronic databases, including PubMed/MEDLINE, Google Scholar, and Cochrane Library, for publications from January 2010 to December 2023. Key search terms included: “pediatric diabetes”, childhood diabetes mellitus, type 1 diabetes children, type 2 diabetes adolescents, monogenic diabetes, diabetic ketoacidosis pediatric, continuous glucose monitoring children, psychosocial impact diabetes children, and diabetes technology pediatric. Priority was given to meta- analyses, randomized controlled trials (RCTs), large cohort studies (e.g., SEARCH, DCCT/EDIC, TODAY), and consensus guidelines from professional bodies such as the International Society for Pediatric and Adolescent Diabetes (ISPAD), the American Diabetes Association (ADA), and the National Institute for Health and Care Excellence (NICE). References from identified articles were also hand-searched for additional relevant sources. Data on epidemiology, diagnostic criteria, treatment protocols, and out- comes were extracted, analyzed, and synthesized to present a current and evidence- based overview of the field.

Classification and Pathophysiology
Pediatric diabetes is not a homogenous entity. Accurate classification guides management and prognostic counseling.
