ABSTRACT: OBJECTIVE:To examine the prevalence and correlates of non-severe hypoglycemia among adolescents with type 1 diabetes and suboptimal glycemic control, an understudied topic in this group. METHODS:Seven days of blinded continuous glucose monitor data were analyzed in 233 adolescents at baseline of the Flexible Lifestyle Empowering Change trial (13-16 years, type 1 diabetes duration >1?year, and hemoglobin A1c [HbA1c] 8-13% [64-119?mmol]). Incidence of clinical hypoglycemia (54-69?mg/dL) and clinically serious hypoglycemia (<54?mg/dL) was defined as number of episodes ?15?minutes. Logistic regression modeling was used to determine the correlates of long duration of hypoglycemia, categorized by median split among those who experienced hypoglycemia. RESULTS:The sample was 76.1% non-Hispanic white, 49.8% female, age?=?14.9?±?1.1?years, diabetes duration?=?6.4?±?3.7?years, and HbA1c?=?9.6?±?1.2% (81?±?13?mmol/mol). Over 7 days, 79.4% of youth experienced ?1 hypoglycemic episodes of <70?mg/dL, and 55.4% of youth experienced ?1 hypoglycemic episodes of <54?mg/dL. Among all adolescents, the median duration of clinical hypoglycemia and clinically serious hypoglycemia was 21.9 (range 0-250.2) and 4.3 (range 0-209.7) minutes/day, respectively. Long duration of clinical hypoglycemia (range 1.8-17.4% time overall) and clinically serious hypoglycemia (range 1.2-14.6% time overall) was associated with older age and decreasing HbA1c. Long duration of clinically serious hypoglycemia also was associated with insulin pump use. CONCLUSIONS:Almost 80% of adolescents with elevated HbA1c had an episode of clinical hypoglycemia, and?>50% had clinically serious hypoglycemia in a week. Increased education alongside access to emerging diabetes technologies may help to prevent hypoglycemia while improving glycemic control.
