- Background & Objectives : HRV is one of the most promising and popular markers of cardiac autonomic activity. It is a non invasive technique having significant diagnostic, clinical and research application. Rapid weight gain is associated with increased cardiac sympathetic tone in humans. There is a lack of autonomic imbalance studies involving young obese individuals. This study is an effort to assess the effect of obesity on cardiac autonomic activity using Heart Rate Variability in young adults in normal weight and obese subjects. Methods: 140 young adults 18-25 years were categorized into BMI based, normal and obese groups. Raw data for HRV analysis was a ‘lab chart recording’ of heartbeat signal from a pulse transducer in a resting subject for 5 min. at 1000 samples/sec. Results: There was a significant (p<0.01) decrease in SDNN, E/I ratio, HF nu and a significant (p<0.01) increase in LF nu, LF/HF in cases when compared to controls. Interpretation & Conclusion: In Obese group, study showed a statistically significant reduction in parasympathetic activity and a statistically significant increase in sympathetic activity. There was a shift in the sympathovagal balance towards sympathetic predominance among obese young adults in contrast to normal young adults.
