Background: Offspring of hypertensive parents have been reported to have alteration on their sympathovagal balance and have exaggerated response to stressful conditions. Many Christians observe a period of fasting at the beginning of every year, which imposes some stress on their bodies. Objective: This study aims to investigate the effect of 21-day intermittent fasting on some cardiovascular parameters in offspring of hypertensive and normotensive parents. Materials and Methods: Eighty young adults (20–28 years) were divided into equal number of male and female offspring of hypertensive and normotensive parents based on questionnaire. Their body weight, height, waist circumference (WC), body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were recorded 1 week before the fasting period began and then weekly for 3 weeks, in which they fasted. Results: The weight, BMI, and WC reduced during fasting, but the reductions were not significant (P > 0.05). The SBP and DBP were higher in male offspring of hypertensive parents than all other groups. SBP was also significantly (P < 0.05) higher in males than females before fast and during fast. Fasting significantly reduced the SBP in the male offspring of both hypertensive and normotensive parents. The HR reduced in the females during fast but increased from a lower level in males to a value not significantly different from prefasting level. Conclusion: Fasting reduces the high SBP and DBP in male offspring of hypertensive parents, which is beneficial to their cardiovascular system.
