Effects of Ramadan Fasting, Physical Activity, and Dietary Patterns on Diabetic and Hypertensive Patients

Introduction: The present study aimed to compare the effects of Ramadan fasting and dietary patterns on the blood pressure, fasting glucose level, and body mass index (BMI) of patients with diabetes mellitus (DM), hypertension (HTN), DM and HTN, and healthy subjects.  Methods: This prospective, cross-sectional study was conducted in Shaban, Ramadan, and Shawwal months in ۲۰۲۰ on ۱۵۵ subjects who were divided into groups of HTN (G۱; n=۴۲), DM (G۲; n=۳۲), DM and HTN (G۳; n=۴۱), and healthy (G۴; n=۴۰). The subjects were interviewed three times during the study period to collect data on demographics, dietary habits, and physical activity. In addition, physical parameters (height and weight) and clinical parameters (systolic and diastolic blood pressure and fasting blood sugar) were measured in each visit. Data were collected three times in the last ten days of each month. Data analysis was performed using the repeated measures ANOVA. Results: Mean weight and BMI reduced significantly from Shaban (V۱) to Ramadan (V۲). Systolic and diastolic blood pressure also reduced significantly from V۱ to V۲. Moreover, the mean sleeping hours significantly decreased from V۱ to V۲. Considering Tarawih prayer as physical activity, a significant increase was observed in the mean metabolic energy turnover value from V۱ to V۲. Mean calorie, carbohydrate, and sodium intake also increased significantly from V۱ to V۲, while they reversed significantly to almost the same values in V۳. Protein and cholesterol consumption decreased significantly from V۱ to V۲, while the value reversed significantly in V۳. Conclusion: According to the results, Ramadan fasting could effectively control the blood pressure and glucose levels of the patients. Furthermore, physical activity increased significantly due to Tarawih prayers, and carbohydrate, sodium, and calorie intake increased as well. On the other hand, a reduction was denoted in protein and fat consumption. Glucose levels significantly decreased in the diabetic patients, and blood pressure significantly reduced in the hypertensive patients.
