Objective: Our study aims was to evaluate the effect of Ramadan fasting on routine biochemical parameters in elderly subjects with cardiovascular risk factors. Design : Cohort study. Setting: Subjects were prospectively recruited and screened at nine primary care clinics, three outpatients specialized clinics and an emergency departement. Participants: subjects aged ≥ 65 years (n=87) recruted in Ramadan month in 2010, 2011 and 2012. Measurements: Dietary intake using a 24 hour recall, biochemical tests including complete lipid profile (total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), renal function tests, serum uric acid, serum electrolytes (sodium, potassium, chloride and protein), glycaemia, and glycated hemoglobin (HbA1C). All data related to dietary intake and biochemical tests were performed one month before Ramadan, during the last week of Ramadan and one month after Ramadan. Comparison between the three time groups were made using standard statistical tests. Results: We showed a significant decrease of creatinine clearance and an increase of serum triglycerides and blood glucose during Ramadan. After Ramadan, we observed a significant increase in HDL-C was and a significant decrease in serum triglycerides and HbA1c. No correlation was found between glycaemia and total energy intake, neither between LDL-C/HDL-C ratio and total energy intake. Conclusion: In elderly subjects with cardiovascular risk factors, Ramadan seems to induce dual effects. During the fasting period, there is a potential risk of renal function decrease and an increase of glycaemia. In contrast, after Ramadan, our findings support the potential beneficial effect of fasting on lipid regulation and glycemic control.
