Time in tight glucose range in adolescents and young adults with diabetes during Ramadan intermittent fasting: Data from real-world users on different treatment strategies

Diabetes Res Clin PractPublished Prospective cohort study

Authors' conclusion

At the end of Ramadan, TITR was decreased in patients with T1DM except those using AHCL who had similar levels to non-insulin-treated T2DM patients. Advanced technology has the potential for achieving tight glycemic targets, along with a reduction in CoV, without increasing hypoglycemic risk compared with other insulin treatment modalities.

Study context

Population
Adolescents and young adults with diabetes during Ramadan intermittent fasting
Exposure
Time in tight range (TITR) across treatment strategies (MDI + intermittently scanned CGM (isCGM), sensor augmented pump (SAP), advanced hybrid closed loop (AHCL) in T1D) vs non-insulin-treated T2D during Ramadan fasting
  • T2DMn = 276
  • T1DMn = 426
Outcome
Attainability of TITR (70-140 mg/dL) target
Follow-up
End of Ramadan
