Obesity city

From the Sunday Age :

Surge in obesity


January 17, 2010
Three per cent of Australians are believed to be in the most extreme category of obesity.

Body Mass Index is calculated by dividing a person's weight in kilograms by their height in metres. While a healthy BMI is considered to be between 20 and 25, Dr Frydenberg reported seeing patients with BMIs of 70. An index of 30 is classified obese, 40 morbidly obese and more than 50 super obese.


Body Mass Index is defined as the individual's body weight divided by the square of their height.

If it was as the Sunday Age said, a teenager 1.7 metres high who weighed 45 kilos (rather than 75) would be overweight, and one who weighed 51 kilos (rather than 90 kilos) would be obese.

Stupid, dangerous, and the trigger for an epidemic of eating disorders. And they haven't corrected it online, either.

Papa and I noticed this too.

We went to Wikipedia and found a new exponent: 2.3-2.7 instead of square.
