A Prospective Comparative Study Comparing Cardiovascular Reactivity in Obese Young Adult Male and Female Individuals.

ABSTRACT

Background: Cardiovascular reactivity (CVR) is defined as increase in heart rate (tachycardia) and blood pressure (hypertension) due to stress by the activation of sympathetic nervous system. Methods: Students of 18-25 years of age of various courses at Teerthanker Mahaveer Medical College, Body Mass Index (BMI) > 18 kg/m2 and self-reported teetotallers was enrolled for the study. After recording the basal parameters, all subjects underwent various pressor stimuli and haemodynamic parameters were recorded accordingly. Results: All values dPulse was higher in female (0.87/min) than obese male (0.38/min), dSBP & dDBP was higher in Obese male (1.88mmHg &2.14mmHg) than obese female (1.16mmHg &1.09mmHg) with significant difference. HR showed insignificant difference by all stressors except just after 1min of Videogame. Blood pressure was higher in male subject’s after1min/5min of stress with significant difference after 1min.of CPT/cycling/videogame. This is due to progesterone and due to their large musculature body. Conclusion: Obese male individual showing lower resting pulse rate but higher SBP &DBP than obese female subjects.CVR to stress, result was remains same dPulse was higher in female & the blood pressure was higher in obese male group with insignificant difference except 1min after 1min of VG.
