Influence of Disease Course and Comprehensive Management on Blood Glucose Level in Children and Adolescents with Type 2 Diabetes Mellitus.

AbstractAims/IntroductionThe aim of the present study was to evaluate the status of glycemic control, and assess the effects of the disease course and comprehensive management measures on the blood glucose level in children and adolescents with type 2 diabetes mellitus.Materials and MethodsThe study collected the clinical data of type 2 diabetes patients in Beijing Children's Hospital from January 2015 to September 2020. Patients were grouped based on the disease course to compare their glycated hemoglobin (HbA1c) level, islet β‐cell function, insulin resistance and comprehensive management measures.ResultsOf the 170 participants, the median disease course was 2.0 years (interquartile range [IQR] 1.0–4.0 years). The baseline HbA1c was 11.2% (IQR 9.2–12.4%). According to the grouping by the disease course, the median HbA1c was the lowest (5.7% [IQR 5.3–6.1%]) in the half‐year course group and the highest in the 4‐year course group (9.0 [IQR 6.8%–11.3%]). Compared with the group with a disease duration <2 years, patients in the >4 years group had a lower proportion of patients with HbA1c <7% (29.2% vs 66.2%), a lower homeostasis model assessment of β‐cell function, and a lower proportion with a controlled diet, moderate‐intensity exercise, regular follow up and no drug treatment. We deemed HbA1c as the dependent variable, and found that disease duration, homeostasis model assessment of β‐cell function at follow up, continuous moderate‐intensity exercise, regular review and treatment regimen were significant influencing factors for glycemic control.ConclusionsChildren and adolescents with type 2 diabetes and a prolonged disease course showed poor glycemic control and decreased islet β‐cell function. A good lifestyle, especially moderate‐intensity exercise, can help such cases better control their blood glucose level.
