Survey on diabetic patients treated with insulin during the fasting month of Ramadan

Aim: To estimate the proportion of diabetic patients on insulin, who interrupt fasting during Ramadan, and describe the reported reasons of this interruption. Design: This is a national observational survey of diabetic patients treated with insulin and fasting during the month of Ramadan 2013, proposed to all endocrinologists willing to participate. Consecutive patients were included until the required sample size, estimated at 498 patients, was obtained. Conducted among patients recruited by endocrinologists during the month following Ramadan 2013. Results: Five hundred twenty-six (526) patients were included, of which 51 (9.7%) had type 1 diabetes. The mean age was 36.8 [+ or -] 11.6 and 58.3 [+ or -] 10.0 years for type 1 and type 2 diabetes, respectively. The proportions of male subjects were 62.8% and 57.5% for type 1 and type 2 diabetes, respectively. The mean duration of diabetes was 11.0 [+ or -] 8.8 and 14.4 [+ or -] 7.9 years for type 1 and type 2 diabetes, respectively. During Ramadan, more than 55% (54.9% and 55.8% for type 1 and type 2 diabetes, respectively) of patients were treated with insulin analog and over a third with mixed insulin. In this study population, 71.5% reported having fasted without interruption during the month of Ramadan. The average number of non-fasted days was 3.0 [+ or -] 6.7, mainly due to hypoglycemic episodes. Conclusion: According to this observational survey conducted in Tunisia, most patients with diabetes treated with insulin (insulin in more than half of the cases) were able to fast without interruption during Ramadan.
