Background: We investigated the association of body mass index (BMI) measurements in adult hypertensive patients with normal weight and overweight including obesity.Methods: This was a randomized study performed in Udaipur, India, on 200 hypertensive patients aged (32-90) years. Patients were divided according to their body weight (normal weight vs overweight and obesity) into two groups. Weight, height and BMI were measured to estimate the various categories of bodyweight.Results: We found significant relations between body weight and blood pressure. Patients with normal weight had a normal blood pressure. However, a significant increase in blood pressure was observed in patients with overweight and obesity.Conclusions: BMI is related with weight status in hypertensive overweight / obese patients.
