The Abdominal Volume Index (AVI) Calculator measures the volume of the abdomen, helping to assess the distribution of body fat. AVI is useful for identifying risks related to central obesity, which can lead to health issues such as cardiovascular diseases, type 2 diabetes, and metabolic syndrome. By using the AVI Calculator, you can understand your abdominal fat distribution and take steps to maintain a healthy lifestyle.

## Formula of Abdominal Volume Index Calculator

The formula for calculating the Abdominal Volume Index (AVI) is:

where:

- waist is the circumference of the waist in centimeters
- hip is the circumference of the hips in centimeters

## Reference Table for AVI Calculations

Here is a reference table with pre-calculated AVI values for common waist and hip measurements. This can help you quickly find your AVI without performing the calculations each time.

Waist (cm) | Hip (cm) | AVI |
---|---|---|

70 | 90 | 12.65 |

80 | 100 | 16.94 |

90 | 110 | 21.63 |

100 | 120 | 26.72 |

110 | 130 | 32.21 |

## Example of Abdominal Volume Index Calculator

Let's go through an example to see how the AVI is calculated.

Example:

- Waist circumference: 85 cm
- Hip circumference: 100 cm

Step-by-step calculation:

- Calculate 2 * waist^2: 2 * 85^2 = 2 * 7225 = 14450
- Calculate 0.7 * (waist - hip)^2: waist - hip = 85 - 100 = -15 (waist - hip)^2 = (-15)^2 = 225 0.7 * 225 = 157.5
- Sum the results and divide by 1000: (14450 + 157.5) / 1000 = 14607.5 / 1000 = 14.61

So, the AVI for a waist circumference of 85 cm and a hip circumference of 100 cm is 14.61.
