A Real-World Prospective Study of the Effectiveness and Safety of Automated Insulin Delivery Compared With Other Modalities of Type 1 Diabetes Treatment During Ramadan Intermittent Fasting

Diabetes CarePublished Prospective cohort study

Authors' conclusion

Use of AID is associated with the highest rates of fasting and best glycemic control during Ramadan fasting.

Study context

Population
People with T1D who attempted fasting during Ramadan 2022
Participants
294 people
Exposure
Automated insulin delivery (AID) vs other T1D treatment modalities during Ramadan fasting
  • AIDn = 62
  • Conventional pump + continuous glucose monitoring (CGM)n = 37
  • Pump + self-monitoring of blood glucose (SMBG)n = 8
  • Multiple daily injections (MDI) + CGMn = 155
  • MDI + SMBGn = 32
Outcome
Median days fasting broken because of diabetes
Follow-up
Ramadan

Main finding

As reported in the abstract

P = 0.047

Observational data: associations, not effects.

Further findings

Double target: fast broken ≤2 days because of diabetes and TIR ≥70% · Ramadan

Glycemic metrics (time in range (TIR), glycemia risk index, TBR, TAR) · Ramadan

AID: significantly greater TIR and lower glycemia risk index, TBR and TAR vs conventional pump and MDI users (both P < 0.05)

Double target: fast broken ≤2 days because of diabetes and TIR ≥70% · Ramadan

AID vs conventional pump and vs MDI + CGM (both P < 0.05)

Fasting most days of Ramadan (breaking fast ≤2 days)

AID users twice as likely to complete fasting most days vs MDI + CGM users
  • Multivariable logistic regression
