Calcule a relação cintura-quadril e a categoria de risco à saúde a partir dessas medidas.
What is a Calculadora de Cintura-Quadril?
Waist-to-hip ratio is a simple indicator of where body fat is concentrated — fat carried around the waist ('apple' shape) is associated with higher cardiovascular risk than fat carried at the hips ('pear' shape) at the same total body weight, which is why the WHO tracks this ratio alongside BMI rather than as a replacement for it.
How to use the Calculadora de Cintura-Quadril
- Enter your gender, waist circumference, and hip circumference
- Press Calculate
- Your waist-to-hip ratio and WHO risk category appear instantly, computed on your device
Formula
WHR = Waist circumference ÷ Hip circumference
A simple ratio — both measurements must be in the same unit, since the units cancel out in the division.
Example
A waist of 85cm and hip of 100cm gives a ratio of 0.85 — for a woman, that falls right at the boundary between the WHO's "moderate risk" and "high risk" bands, while the same 0.85 ratio would read as "low risk" for a man, since the thresholds differ by gender.
Common mistakes
- Measuring waist at the belt line instead of the narrowest point (or navel), which can meaningfully skew the ratio.
- Using inconsistent units for waist and hip (e.g. one in inches, one in centimeters) — both must match.
- Applying the male risk thresholds to a female measurement, or vice versa — the WHO's risk bands differ by gender.
Frequently asked questions
What waist-to-hip ratio is considered healthy?
The WHO generally considers below 0.90 low risk for men and below 0.80 low risk for women, with risk increasing above those thresholds — though like BMI, it's a screening indicator, not an individual diagnosis.
Why do risk thresholds differ by gender?
Men and women naturally carry fat in different distribution patterns on average, so the same numeric ratio doesn't carry the same health implication across genders — the WHO's thresholds were set separately based on population health outcome data for each.
Where exactly should I measure waist and hip?
Waist: at the narrowest point of the torso, usually near the navel. Hip: at the widest point around the buttocks. Measure both snug against the skin without compressing it, standing relaxed rather than pulling in the stomach.
Is WHR better than BMI for assessing health risk?
Neither replaces the other — WHR captures where fat is distributed (which correlates with cardiovascular risk), while BMI captures overall weight relative to height. Many health guidelines recommend looking at both together rather than picking one over the other.
