A substantial proportion of children diagnosed with type 1 diabetes mellitus (T1DM) present with overweight or obesity, raising questions about how excess adiposity influences disease presentation. A retrospective registry-based analysis published in Frontiers in Endocrinology evaluated the prevalence and clinical profile of overweight and obesity among children with newly diagnosed T1DM in Kuwait.

The analysis included 1,265 children aged 14 years or younger from the Childhood-Onset Diabetes electronic Registry (CODeR), with diagnoses established using International Society for Pediatric and Adolescent Diabetes (ISPAD) 2018 criteria. Overweight or obesity, defined by World Health Organization (WHO) growth standards, was identified in 29.9% of cases. Males were more frequently affected than females (55.3% vs 44.9%; p=0.001). Children with overweight or obesity were older at diagnosis compared with those without excess weight (median 9.3 vs 7.3 years; p=0.0001).

At presentation, the overweight or obese group showed fewer cases of diabetic ketoacidosis (DKA), along with lower glycated hemoglobin (HbA1c) and triglyceride levels. Adjusted analyses demonstrated that higher body mass index (BMI) z-scores were associated with lower HbA1c, reduced odds of DKA, and lower likelihood of celiac autoimmunity.

These findings indicate that overweight and obesity are common at T1DM onset and are associated with a milder metabolic presentation. The results support consideration of early screening and risk stratification, although longitudinal data are required to clarify implications for disease progression.
