Assessment of the IDF-DAR Fasting Risk Assessment Tool to Predict Type 1 Diabetes-Related Complications During Ramadan in a Real-World Setting.

Overview

Alguwaihes AM et al.. Clin Med Insights Endocrinol Diabetes 2025 · PMID 41001082 · DOI 10.1177/11795514251376888

Among 963 Saudi adults with type 1 diabetes, those rated high risk had more complications and emergency visits when fasting.

Does the study support the specific claim? No · Methodological quality: low

Original publication

Plain-language summary

Study explained simply
What did the researchers want to find out?

Test a fasting risk tool.

How was the study done?

Online survey after Ramadan 2022.

How many people, animals or samples were studied?

963 adults with T1D.

What was actually found?

High-risk group: more ER visits; education linked to fewer visits.

How large was the observed effect?

OR 0.53 (0.34-0.82) for education.

What do the results mean in everyday life?

Fasting with type 1 diabetes can lead to emergencies; preparation with doctors helps.

What are the study's limitations?

Self-reported; no lab confirmation.

What does it say about Elawady's specific claim?

Contradicts the idea that high sugar during fasting is harmless.

Do the results apply to Germany and Europe?

Directly relevant to Arab populations including Egypt.

What can explicitly not be concluded from this study?

Exact DKA rates.

2. Research question

Does the IDF-DAR 2021 risk calculator predict complications in adults with type 1 diabetes fasting Ramadan?

3. Study design and population

Study design
Cross-sectional study – Cross-sectional online survey
Population

Adults with type 1 diabetes in Saudi Arabia who observed Ramadan 2022

Country

Saudi Arabia

Period

May-August 2022

Sample size

963 (257 men, 706 women; mean age 26.5)

Inclusion and exclusion criteria

not stated in abstract

4. Methods and endpoints

Exposure / intervention

IDF-DAR risk category; pre-Ramadan education

Comparator

Moderate-risk group; no education

Endpoints

Days fast broken, complications, diabetes-related ER visits

Statistical methods

Group comparisons; odds ratios

5. Actual results

Results

66% high risk, 34% moderate risk, none low risk. High-risk group: more days with broken fast, more complications, more diabetes-related ER visits (P<.01). Pre-Ramadan education associated with lower odds of ER visit (OR 0.53, 95% CI 0.34-0.82).

Absolute risks

not reported

Authors' conclusion

The IDF-DAR risk calculator predicts acute complications and ER visits; pre-Ramadan education may reduce complications.

6. Strengths

  • Large regional sample
  • Real-world setting relevant to Arab countries

7. Weaknesses

  • Self-reported online survey; recall and selection bias
  • No objective confirmation of DKA

8. Risk of bias

Overall risk of bias
high
Rationale

Self-report, self-selection, confounding of education effect.

9. Assessment of the statistical interpretation

OR 0.53 is an odds ratio from cross-sectional data, not a causal risk reduction (stats/I-FAST-109_idf_dar_tool.py).

10. Relevance to the specific claim

Shows fasting with type 1 diabetes leads to emergency visits in a regional population, especially in high-risk individuals.

11. Independent contrary findings

12. Transferability to Germany and Europe

Universal biology; applies in Europe and Egypt.

13. Overall methodological judgement

Regional evidence that fasting with T1D carries real acute risk requiring assessment and education.
