The prevalence of childhood overweight and obesity has risen in the US during the last 30 years.1 Obesity is prevalent
among children with type 2 diabetes, but recent studies reveal that children with type 1 diabetes (T1D) are also overweight
and obese.2,3 In children with T1D, obesity has been linked with an increased risk for metabolic syndrome.4,5
Furthermore, adults who gained excessive weight during the Diabetes Control and Complications Trial had greater rates of
metabolic syndrome and atherosclerosis during the Epidemiology of Diabetes Interventions and Complications follow-up
study.6,7 Given the adverse consequences of excess weight for individuals with T1D, a better understanding of the evolution
of weight patterns during the first year after the diagnosis of T1D may be important for identifying subgroups of children
who may be at particular risk for excess weight gain and for the design and timing of lifestyle intervention strategies that could
mitigate excess weight gain. Although in previous studies authors have examined
weight gain in children with newly diagnosed T1D,8-10 they were either small,
single-center studies, retrospective case analyses, or the authors examined patients
on older insulin analogues.
