Time in Tight Range (TITR) stratified by Time Below Range (TBR) in a cohort of patients with type 1 Diabetes Mellitus and Multiple Daily Injections. A real-life study.
Objetive: To analyze the Time in Tight Range (TITR) (70-140 mg/dL) and assess their possible differences according to Time Below Range (TBR) in a cohort of type 1 diabetes mellitus people with Múltiple Daily Injections.
Patients and methods: 355 adult users of Continuous Glucose Monitoring (CGM) with at least a HbA1c during the period October 1, 2023-October 1, 2024, and glucose data in the 90 days prior were included.
Results: Age 46.9 years (SD 13.6); 57.2% male; time of evolution 21.6 years (SD 12.6). Mean TITR was 38.4% (SD 14.6) and 20.3% had a TITR ≥ 50%. The correlation TITR-TIR was strong (β = 0.83; CI 95% 0.8-0.87; R [2] Adjusted 0.89; p < 0.001) and varied according to TBR [TBR < 4% group (β = 0.81; CI 95% 0.78 to 0.85; R [2] Adjusted 0.9; p < 0.001) vs. TBR ≥ 4% (β = 0.9; CI 95% 0.86 to 0.94; R [2] Adjusted 0.93; p < 0.001)]. The variables independently associated with TITR in patient with TBR < 4% were HbA1c (β = -9.58; CI 95% -10.88 to -8.29; p < 0.001) and Coefficient of Variation (CV) (β = -0.38; CI 95% -0.66 to -0.11; p = 0.007). However, in those with TBR ≥ 4% were male gender (β = 2.86; CI 95% 0.26 to 5.45; p = 0.031), HbA1c (β = -7.53; CI 95% -9.1 to -5.96; p < 0.001) and CV (β = -0.69; CI 95% -1.01 to -0.37; p < 0.001).
Conclusions: The correlation between TITR and TIR and the factors that were independently associated with TITR differ depending on the TBR.
期刊介绍：
Acta Diabetologica is a journal that publishes reports of experimental and clinical research on diabetes mellitus and related metabolic diseases. Original contributions on biochemical, physiological, pathophysiological and clinical aspects of research on diabetes and metabolic diseases are welcome. Reports are published in the form of original articles, short communications and letters to the editor. Invited reviews and editorials are also published. A Methodology forum, which publishes contributions on methodological aspects of diabetes in vivo and in vitro, is also available. The Editor-in-chief will be pleased to consider articles describing new techniques (e.g., new transplantation methods, metabolic models), of innovative importance in the field of diabetes/metabolism. Finally, workshop reports are also welcome in Acta Diabetologica.
