Abstract:
Objectives: Regular retrospective review of glucose data is an important aspect of type 1 diabetes (T1D) management. Continuous glucose monitors (CGMs) facilitate retrospective review by capturing glucose data and generating standardized reports. However, only a minority of adults with T1D retrospectively review their glucose data, and adolescents are understudied. The objectives of this study were to determine the prevalence of self-reported retrospective glucose data review by adolescents with T1D, determine factors associated with self-reported retrospective glucose data review, and assess whether self-reported retrospective glucose data review was associated with improved glycemia. Methods: We conducted a cross-sectional survey of adolescents aged 12-18 years with T1D in conjunction with review of the associated electronic medical record, which included age, sex, date of diagnosis, clinic hemoglobin A1c (HbA1c), type of insurance, and CGM data. The survey included the Hypoglycemia Fear Survey (HFS) and questions regarding habits and attitudes associated with retrospective review. Results: 112 out of 218 eligible individuals completed the survey (51%). Fifty-three percent of adolescents who completed the survey reported that they had engaged in retrospective glucose data review. Of these, 88% of individuals reported that they reviewed data regularly. Age, sex, race, type of insurance, and CGM use were not associated with retrospective review status. Self-report of retrospective glucose data review was associated with improved glycemia as measured by HbA1c and time in range (TIR) compared to adolescents who indicated they do not review glucose data (p=0.006 and p=0.04, respectively). There was no difference in HFS scores between reviewers and nonreviewers including the behavioral subscale, worry subscale, and total score. Conclusions: Self-report of retrospective glucose data review was associated with improved glycemia as measured by HbA1c and TIR. Adolescent-initiated glucose data self-review does not appear to be driven by fear of hypoglycemia (FoH).

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
