Background: In obesity, as excessive tissue accumulates, an altered metabolic profile occurs along with a variety of adaptations/ alterations in the cardiac structure and functions even in the absence of co morbidities. Aim&Objectives: To compare the Heart rate variability analysis between the pre-prandial and postprandial state in obese and non obese young healthy females. Materials & Methodology: 50 obese and 50 non obese young healthy females aged between 21-25 years were selected based on body mass index. Heart rate variability was recorded in both pre and postprandial state by using computer based software device, Digital finger pulse photo plethysmography (DFP) to identify separate frequency components, i.e, total power, low frequency power and high frequency power. Results: All the statistical methods were carried out through the SPSS for windows version 16.0 .The independent samples T test procedure was done to compare the means for the two groups. P value ≤ 0.05 was considered statistically significant. HRV analysis found significantly lower values of LF, HF in millisecond square (ms2) and HF in normalized unit (nu) & higher values of LF (nu) and LF/HF ratio among the obese group in both pre and post prandial state when compared to non-obese group. Conclusion: Our data indicate that obese subjects have decreased parasympathetic activity as evidenced by decrease in Total Power(TP)(ms2), Low Frequency(LF)(ms2), High Frequency(HF)(ms2) and High Frequency( nu) and increase in sympathetic activity as evidenced by increase in HR, LF( nu) and LF/HF ratio in both pre and post prandial state.
