What is the Body Roundness Index (BRI)?

The Body Roundness Index (BRI) is a measure of body fat distribution, focusing on how much your body shape resembles a circle. It is calculated using your height and waist circumference. Unlike BMI, BRI considers the distribution of fat, particularly visceral fat, which is linked to health risks such as cardiovascular disease and diabetes.

Why is BRI Important?

BRI provides a more accurate assessment of health risks related to body fat distribution. It helps identify individuals at risk for conditions like metabolic syndrome, hypertension, and insulin resistance. A higher BRI indicates a higher concentration of visceral fat, which is more dangerous than subcutaneous fat.

How to Use the BRI Calculator

Follow these steps to calculate your BRI:

1. Measure Your Height: Stand straight and measure your height in centimeters (cm).
2. Measure Your Waist Circumference: Use a measuring tape to measure your waist at the midpoint between the bottom of your ribs and the top of your hips.
3. Enter Your Values: Input your height and waist circumference into the calculator.
4. Calculate: Click "Calculate BRI" to see your results and interpretation.

Interpreting Your BRI Results

Based on studies, BRI values can be interpreted as follows:

• BRI < 3.41: Moderate increase in health risks (25% higher risk of mortality).
• BRI 3.41–4.44: No significant increase in health risks.
• BRI 4.45–5.45: Low risk for health problems related to visceral obesity.
• BRI 5.46–6.91: Moderate increase in health risks.
• BRI > 6.91: High risk of health problems related to visceral obesity (50% higher risk of mortality).

BRI vs. BMI

Unlike BMI, which only considers height and weight, BRI focuses on waist circumference and fat distribution. This makes BRI a better predictor of health risks related to visceral fat, such as heart disease and diabetes.
