Effect of visceral fat on nighttime blood pressure

Introduction: Nighttime blood pressure is lower compared to that of daytime. Reduction in this blood pressure is a physiological phenomenon. Nighttime blood pressure is a better predictor of outcome than daytime pressure with respect to cardiovascular events. Visceral fat has been shown to be associated with various aspects of blood pressure.

Aim: To assess the effect of visceral fat on nighttime blood pressure in normal individuals.
Materials and Methods: This study included 20 subjects. Visceral fat was measured and ambulatory blood pressure was recorded from 10 pm to 2 hours after waking up for a minimum of 8 hours. Data was analyzed using SPSS Version 17. Pearson’s correlation was used to find the correlation between visceral fat and other parameters. p value < 0.05 was considered as statistically significant.
Results: There were 20 subjects, 15 females, 5 males. Pearson’s correlation shows a significant positive correlation between visceral fat and average nighttime systolic blood pressure (r=0.747, p=
