Correlation Of BMI with Sympathetic skin response and Galvanic skin resistance In Healthy Women

Abstract

Introduction: Body Mass Index (BMI) is the marker for body fat content and is one of the most commonly used parameters to quantify and grade obesity. Obesity, a global epidemic is considered to be a state of Sympathovagal imbalance. BMI (>25kg/m2) is not only risk factor for cardiac disorders but also altered autonomic functions. Sudomotor activity refers to electrical skin conductance of sweat glands by post ganglionic sympathetic type C nerve fibres. Sympathetic skin response (SSR) and Galvanic skin resistance (GSR) are the tools to measure the Sudomotor activity in an individual. The present study is conducted to find correlation of BMI with that of SSR and GSR in healthy women.
