Background: The aim of present study is to find out the effect of body mass index (BMI) on blood pressure level in obese subjects in comparison with the non-obese subjects. We also assessed the relationship of general and central obesity measurement tools like-(BMI, WC, WHpR, WHtR, body fat percentage and SubScapular skinfold thickness) with the systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial blood pressure (MAP) in an obese individuals. Materials & methods: Study included 400 adult subjects both males and females comprising 200 non-obese and 200 obese subjects. 200 obese adults (consisting of 118 adult subjects with BMI>30kg/m2 and 82 adult pre-obese /overweight subjects with BMI >25 to 29.99 kg/m2) subjects within the age group of 30 to 60 years who were attending OPDs in tertiary care hospital. 200 non-obese adults (BMI > 18.50 to 24.99 kg/m2) were selected on voluntarily participation from employees. Anthropometric measurement and blood pressure were recorded. Results: In 200 obese (pre-obese/overweight + obese) and 200 non-obese subjects, the mean values of age in obese subject was (mean 45.96+8.38 years) compared with the mean values of age of non-obese subjects (mean 44.87+9.41years) with the help of unpaired t- test, we can conclude that there was no statistically significant difference seen in the age of participants between the two groups. It was found that the mean value of body fat % and subscapular skinfold thickness of obese subjects was significantly higher than that of non-obese subjects The mean value of waist circumference (WC), waist to hip ratio (WC/HIP) and waist to height ratio (WC/HT) in obese subjects was found to be 100.65+6.80cm, 0.95+0.04 and 0.62+0.04 where as in non-obese subjects it was 86.41+6.62cm,0.91+0.05 and0.52+0.04respctively,when unpaired t test was applied it was found that the mean values of above 3 parameters were significantly higher in obese than that of non- obese subjects. SBP, DBP and MAP has positive association with each anthropometric parameters in obese subjects .i.e. increase in any above mentioned anthropometric parameters in obese population of our study leads to further consistent increase in SBP, DBP and MAP. Conclusion: There is a necessity of creating awareness regarding overweight and obesity and related chronic disease like hypertension which would otherwise become emerging problem in the near future. So, that clinicians should counsel their patients to maintain a healthy BMI or lose weight if they are overweight or obese in order to reduce the future risk of HTN and subsequent CVD.
