Background: A new IDF-DAR (International Diabetes Federation - Diabetes and Ramadan Alliance) risk stratification tool was published in 2021 to better stratify the risk of Ramadan fasting in people with diabetes.
Methods: We performed a prospective, survey-based study before and after Ramadan 1442/2021 to explore the ability of the new IDF-DAR risk stratification tool to predict the probability of fasting and the risk of complications from fasting in people with diabetes.
Results: A pre-Ramadan assessment was completed for 659 patients who intended to fast in Ramadan; 647(98.2%) answered the post-Ramadan follow-up questionnaire. Mean age was 53.5 years and 47.9% were females. 603(91.5%) had type 2 diabetes while 56(8.5%) had type 1 diabetes. Using the IDF-DAR risk criteria at the pre-Ramadan assessment, 339(51.4%) were categorized as low-risk (score <3), 173(26.3%) as moderate-risk (score 3.5-6) and 147(22.3%) as high-risk (score >6). 94.3%, 81.1% and 76.9% patients fasted the full 30 days in the low, moderate and high risk groups respectively (p < 0.0001). Any hypoglycaemia was reported in the low, moderate and high risk groups by 6.3%, 21.9% and 35.0% respectively while severe hypoglycaemia was reported by 3(2.1%) patients in the high, 3(1.8%) in the moderate and none(0%) in the low risk groups. Hyperglycaemia (>250 mg/dL) was reported in the low, moderate and high risk groups by 2.7%, 13.0% and 23.8% respectively.
Conclusion: The new IDF-DAR risk assessment tool appears to reliably predict both the ability to fast during Ramadan as well as the likelihood of getting hypoglycaemia or hyperglycaemia.
