The impact of COVID-19 pandemic on the incidence, presentation, and management of type 1 diabetes in children and adolescents: a narrative review.

Abstract

Type 1 diabetes (T1D) is an autoimmune condition affecting approximately 1.5 million children and adolescents worldwide, with an incidence of approximately 2-3% each year and rising. During the recent COVID-19 pandemic, a significant increase in incidence of T1D in children and adolescents was observed in numerous countries worldwide, with an increased number of newly-diagnosed cases presenting with diabetic ketoacidosis. The increased frequency of T1D presenting with diabetic ketoacidosis has been attributed not only to the SARS-CoV-2 virus itself but also to the restrictions imposed by the pandemic. The shift to telemedicine and unwillingness to seek medical care due to fear of infection contributed to delayed diagnosis and more severe disease presentation. Furthermore, the periods of lockdown that were implemented during the pandemic presented multiple challenges for children and adolescents living with T1D and disrupted the management of their condition. Changes in physical activity and diet as well as shortage of medical supplies during that period have been linked to worsening of glycemic control, which were at least partly offset by increased parental involvement and use of telemedicine.
