The waist to hip ratio is one of several body mass composition measurements used to determine and individual's body fatness. This ratio is simply your waist measurement divided by your hip measurement. A multi-country study (27,000 people from 52 countries), conducted by the Interheart Group, indicates that the it may actually be a better predictor of heart attack than the body mass index (BMI).
The standard body mass index has become the measurement of choice used by many healthcare professionals to evaluate a person's body mass composition (and thus a predictor of the likelihood of chronic illnesses like heart disease, type 2 diabetes and stroke). Let's see why a comparison of your waist to your hip size might be a better indicator of your risk for illness.
First, you'll need a cloth tape measure like those used by tailors. Measure your waist circumference at the narrowest point. You want to find your smallest waist size. Next, measure your hips at the widest point, typically around your buttocks. Divide your waist measurment by your hip measurement and the result is your waist to hip ratio.
The ratio of your waist to hip yields a number which gives healthcare workers an idea of your body shape. A low ratio (bigger hips) means a general body type known as pear-shaped. A high ratio means an apple shape (bigger belly). The more dangerous of the two body shapes is the apple. This is due to the fact that more fat (known as visceral fat) is being stored around your mid-section.
An excess of visceral fat is extremely dangerous. It surrounds your vital organs and can lead to a whole host of serious health issues. If you haven't already done so, go to my page on ideal waist size to read about the dangers of visceral fat.
Whatever measurement you use to determine if you're in an ideal weight range (BMI, waist size, or waist to hip ratio), remember that it's best to look at all these measures in combination to get the most accurate picture of your body mass composition, and how it may affect your long term health prospects.
