Experiment on Correlation Between BMI and Blood Pressure

The Effects of Body Mass Index (BMI) on Blood Pressure

Hypothesis: With a higher BMI, a higher blood pressure will be measured.

Using opportunity sampling, I surveyed eleven willing individuals entering Walmart.


  • CDC’s BMI Calculator
  • Stethoscope
  • Sphygmomanometer

Based on my results, there is no correlation between BMI on blood pressure.

*BMI 30+ = OBESE.

An obese individual’s heart has to put in E X T R A work in order to pump blood throughout the body. In result, the arteries may resist this strong blood flow and increase blood pressure (Jiang, 2016).

Individual A: 118/56

Individual B: 120/48

Normal Systolic Blood Pressure: 100-140 mmHg.

Normal Diastolic Blood Pressure: 60-90 mmHg.

The participants in the investigation remained within normal range besides two individuals with low diastolic blood pressure.

**Higher salt intake could have impacted the low diastolic blood  pressure (Windsor, 2015).

With a greater number of participants, a correlation may have occurred.
