The objective of this study was to ascertain the risk of hypoglycemia among youth with type 2 diabetes (T2D) on insulin therapy. Twenty-two youth with T2D on insulin therapy (M=12, F=10, age=14.4±4.0 years) were enrolled from a single pediatric endocrine practice. They were followed-up for 3 months with weekly phone calls and monthly in-person visits to review blood glucose logs and document any signs or symptoms of hypoglycemia (defined as finger stick glucose of ≤70 mg/dL). Episodes of hypoglycemia were categorized into five categories: Severe, documented symptomatic, asymptomatic, probable symptomatic and relative hypoglycemia. In addition to examining the risk of hypoglycemia, the degree to which hypoglycemia was associated with patient demographics (e.g. age, gender and body mass index [BMI]) or clinical factors (i.e. duration of diabetes, duration of insulin treatment, glycemic control or insulin dose and regimen) was determined. Nine hypoglycemic events occurred during the study period in five patients with an incidence rate of nine events per 5.3 patient-years. Of the hypoglycemic events, five were symptomatic and four were asymptomatic. No severe hypoglycemic events occurred. Hypoglycemia was not associated with age, ethnicity, duration of insulin treatment, insulin dose or initial hemoglobin (HbA1c). However, a significant difference in BMI was noted, with T2D youth who experienced hypoglycemia having a lower BMI than those who did not experience hypoglycemia. The results of this study suggest that the risk of hypoglycemia in youth with T2D on insulin therapy is low.
