Conicity Index Calculator

Calculate your Conicity Index to assess cardiovascular disease risk based on your body shape. This index evaluates how your body shape resembles a cone, indicating central fat distribution.

The Conicity Index is a measure that assesses cardiovascular risk by evaluating body shape:

Category	Men (CI Range)	Women (CI Range)	Cardiovascular Risk
Low Risk	< 1.25	< 1.18	Healthy body shape
Moderate Risk	1.25 - 1.34	1.18 - 1.24	Some central fat accumulation
High Risk	≥ 1.35	≥ 1.25	Significant central obesity

Note: Gender-specific thresholds reflect biological differences in body fat distribution patterns and cardiovascular risk factors.

What is Conicity Index?

Conicity Index (CI) is an anthropometric measurement that evaluates how closely your body shape resembles a cone. Developed in the 1990s, it's designed to assess central obesity and cardiovascular disease risk by analyzing the relationship between waist circumference, weight, and height.

Fun fact: The Conicity Index was developed by Brazilian researchers in 1999 as a way to identify people with apple-shaped bodies who carry dangerous visceral fat around their organs, even when their overall weight appears normal.

Unlike simple waist measurements, CI accounts for your overall body size, making it more accurate for people of different heights and builds. A higher CI indicates a more cone-like body shape with excess abdominal fat, which is associated with increased health risks.

CI is particularly useful because it provides gender-specific thresholds that account for natural differences in body fat distribution between men and women.

How is Conicity Index Calculated?

The Conicity Index formula incorporates three key measurements:

CI = Waist Circumference (m) ÷ [0.109 × √(Weight (kg) ÷ Height (m))]

The calculation process involves:

Convert all measurements to metric: Weight in kg, height in meters, waist in meters
Calculate the denominator: 0.109 × √(Weight ÷ Height)
Divide waist by the result: This gives you your CI value

The 0.109 constant was derived from statistical analysis of thousands of body measurements to create the most accurate assessment tool.

Understanding Your Results

Conicity Index values and their health implications:

Low Risk (Men < 1.25, Women < 1.18): Healthy body shape with minimal central obesity
Moderate Risk (Men 1.25-1.34, Women 1.18-1.24): Some central fat accumulation, monitor lifestyle
High Risk (Men ≥ 1.35, Women ≥ 1.25): Significant central obesity, increased health risks

Gender differences in thresholds reflect biological variations in how men and women naturally store body fat.

Why Conicity Index Matters

Research has shown that higher CI values are associated with increased risk of:

Cardiovascular disease: Heart attacks, strokes, and arterial disease
Type 2 diabetes: Insulin resistance and metabolic dysfunction
Metabolic syndrome: Cluster of conditions including high blood pressure
Sleep apnea: Breathing disruptions during sleep
Certain cancers: Particularly those linked to obesity and inflammation

CI is especially valuable because it can identify health risks in people who have normal BMI but carry dangerous abdominal fat.

Advantages Over Other Measurements

Conicity Index offers several advantages:

Body size adjustment: Accounts for overall body dimensions
Gender specificity: Uses different thresholds for men and women
Central obesity focus: Specifically targets dangerous abdominal fat
Simple measurement: Requires only basic body measurements
Cultural applicability: Validated across different ethnic populations
