Background: Heart rate variability measures the effect of autonomic function on the heart alone. Therefore, it could be the most useful method to investigate the effect of obesity on cardiovascular disease. The present study was conducted to evaluate the correlation between BMI and Heart rate variability in overweight and underweight young adults.  Materials & Methods: The present study was conducted in the department of Physiology on 80 subjects of both genders. Body mass index (BMI) of the subjects were measured by asking the subjects to stand on height measuring stand and the height is measured in meter. After a rest period of 5 minutes, HRV was determined for each of the subjects.  Results: out of 80 subjects, males were 35 and females were 45. The difference was non- significant (P- 0.1). BMI (Kg/ m2) in over weight subjects was 28.2 ± 1.12 and in under- weight 19.1 ± 0.54. Pulse rate in overweight subjects was 86.52 ± 4.2 and in under- weight subjects was 70.42 ± 3.36. The difference was significant (P< 0.05). Average Sup-TP (ms2) in over weight was 1280.3± 125.8 and in underweight was 1811.6± 352.6. Sup-LF (ms2) in over weight was 762.1± 62.8 and in underweight was 828.0± 46.7, Sup-HF (ms2) was 525.2 ± 161.8 and in underweight was 1166.2± 356.2. The difference was significant (P< 0.05). Conclusion: Author concluded that HRV related traits like RP, Sup-LF, Sup-HFnu and Sup-HF values should be periodically monitored for overweight group of people for early detection of heart related complicacy.
