A COMPARATIVE STUDY OF PRE PRANDIAL AND POST PRANDIAL AUTONOMIC NERVOUS SYSTEM RESPONSE BETWEEN OBESE AND NON OBESE YOUNG WOMEN AGED 18-25 YEARS.
In obesity as excessive tissue accumulates, an altered metabolic profile occurs along with a variety of adaptations/ alterations in the cardiac structure and function even in the absence of comorbidities. 1. To study ANS parameters in preprandial and postprandial state in obese and nonobese young healthy females aged 18-25 years. 2. To compare within the groups the ANS parameters in the preprandial and post prandial state. 50 obese and 50 nonobese young healthy females aged 18-25 years were selected based on body mass index. Systolic blood pressure and diastolic blood pressure was recorded using digital electronic blood pressure monitor in both pre and post prandial state. Heart rate and heart rate variability was recorded in both pre and postprandial state using ECG V: 52HRV power spectral analysis to identify separate frequency components, i.e, total power, low frequency power and high frequency power. All the statistical methods were carried out through the SPSS for windows version 16.0 and Minitab version 11.0. The paired samples T test procedure was done to compare the means of two variables for a single group. The independent samples T test procedure was done to compare the means for two groups of cases. P value ≤0.001 was considered statistically significant.HRV analysis found significantly lower values( p=0.001) of TP,LF,HF and HF(nu) ( p=0.001) of LF(nu) and LF/HF ratio, and also increased HR and BP (0.001) among the obese group in both pre and post prandial respectively compare to non obese group. Our data indicate that obese subjects have decreased parasympathetic activity as evidenced by decrease in TP (ms2), LF (ms2), HF(ms2) and HF( nu) and increase in sympathetic activity as evidenced by increase in HR,BP,LF( nu) and LF/HF ratio in both pre and post prandial state.
