AIM: The aim of this study was to determine the correlation between BMI and BP among adults. Methods: The descriptive research study (google form survey) was carried out on adult patient age group 30-90 years with hypertension disease, residing in Jogeshwari, Mumbai between 20 march to 10 April 2020, after being granted approval from the college. Results: We found that 55% of participants were overweight and 27% of participants were obese only 18% of participants were normal/healthy. Therefore, Overweight and obesity are risk factors for HBP. The majority of individuals in this study with HBP are over 50 years old which is further followed by 40-49 years old. Therefore, age is also significantly associated with BP. We also observed that positive family history of HT as well as diabetes was significantly associated with BP. CONCLUSION: The study demonstrated that BMI is closely associated with BP among the elderly population. Because From the results, it is very evident that overweight and obesity occur as a result of less physical activity. All the obese/over-weight participants do not engage in any form of exercise. Exercise is a very important factor to consider in decreasing the incidence of overweight and obesity in populations. This is because exercise helps the body to burn fat and utilizes excess calories. Therefore, the risk of hypertension was higher among population groups who were overweight or obese. BP is also associated with rising age independently. there was a positive and significant correlation among BMI, age, BP. The increased rate of obesity or weight with respect to an increase in age could be due to the fact that older people are less physically active but maintain the same energy intake as during their earlier years. Hence, the excess energy that is not expended is stored as fat, increasing their chances of becoming obese. Prevalence of 27% prehypertension among overweight/obese suggested an early clinical detection of prehypertension and intervention including life style modification, particularly weight management.
