How Does Weight Affect Blood Pressure?

Overview

Objectives/Goals Objectives/ Goals: My project was to determine how weight affects blood pressure in adults. I believe that as our weight or BMI (body mass index) increases, our blood pressure will go up as well. Methods/Materials Methods and Materials: I measured the BMI (derived from the weight and height of the individual) and checked the average blood pressures of 30 people (15 men, 15 women) with a blood pressure cuff. I checked the blood pressure on 3 separate occasions over 3 weeks. I excluded people who had a preexisting condition of high blood pressure or on any medications that would lower blood pressure. Results Results: The experimental results supported my hypothesis by showing that as the BMI increased, so did both systolic and diastolic pressures. In people who are underweight (BMI <18.5) the average blood pressure was 110/68, 118/74 in people with a normal BMI (18.5-24.9), 132/82 in overweight individuals (BMI 25-29.9) and 138/88 in the obese (BMI>30). Conclusions/Discussion Conclusions: My conclusion is that as our weight (BMI) increases, so does our blood pressure.
