Aims and objectives: To compare the blood pressure and pulse rate between normal and obese young adults and to find the correlation between these parameters and BMI.
Material and Methods: After approval from institutional ethics committee and applying inclusion and exclusion criteria a total of 116 subjects of age group 18-25 years were included in the study. After taking informed consent, height and weight were measured and BMI was calculated. The subjects were grouped into normal and obese groups according to BMI. Blood pressure was measured with standard sphygmomanometer in left arm in sitting position after a rest of five minutes. A mean of three recordings was taken into consideration. Pulse rate was recorded as in the examination of pulse from radial artery. After recording these parameters, other parameters like pulse pressure, mean arterial pressure were calculated. Unpaired t test was applied to compare the means of both the groups. Pearsons correlation coefficient was determined to find the correlation between BMI and various parameters.
Results: Systolic, diastolic and mean arterial pressures were higher in obese group than normal and also had positive association with BMI, except for pulse pressure. Pulse rate was also higher in obese group and also showed a positive correlation with BMI.
Conclusion: Thus it was concluded that mean blood pressure and pulse rate were higher in obese subjects than normal and there was a positive correlation of these parameters with BMI. Our results support the necessity to monitor obese asymptomatic youth for high BP.
