Effect of BMI on autonomic function tests amongst Hypertensives and non Hypertensives

Abstract

Hypertension is the most common chronic condition dealt with by primary care physicians and other health practitioners. The autonomic nervous system plays a crucial role in blood pressure (BP) and heart rate (HR) control and may thus be an important pathophysiological factor in the development of hypertension. Detection of hypertension at an initial stage is crucial to prevent microangiopathic damage to the tissue. The present study was undertaken to determine the association between BMI and autonomic function test in hypertensive and non hypertensive. The BMI of subjects in both the groups was derived from their weight (kg) and height (cms). The BMI of hypertensive males and females was Mean SD of 25.84±4.38 and 27.77±4.73 respectively. While, in the normotensive males and females the BMI was Mean SD 22.9±4.0 and 21.94±4.30 respectively. The subjects in both the group underwent autonomic function tests, and the results were correlated with the BMI. Significant correlation (p<0.05) was found amongst the hypertensive groups with BMI >=25 and BMI <25 for valsalva ratio. Physical exercise has impact on BMI as well hypertension. BMI can emerge as an indicator for early detection of hypertension.
