Over Weight And Obese Australian
A person is considered to be overweight when they have more body fat than is considered healthy. This depends on a lot of factors but a rough estimate can be made by measuring a person's BMI, BMI stands for body mass index and compared a person's height to their weight. It is calculated by dividing a person's weight in kilograms by their height in metres squared or by using a chart such as the one shown in. Generally a person is potentially overweight when their BMI is between 25 and 30. A person is considered to be obese when their BMI is over 30.
BMI has a number of limitations. It does not directly measure body fat and a person's weight will also be affected by their amount of muscle mass and bone density. It is only relevant for people over 18 years old and does not take into account factors such as age, gender, ethnicity and body type.
Doctors may use a person's BMI to determine whether other tests including waist circumference, body fat and blood tests are needed.
In 2016 a global study by the medical journal, The Lancet, suggested that overweight and obese people now outnumber underweight people worldwide. Australians are amongst the most overweight people in the world - according to the Australian Government 63% of Australians are overweight or obese. This is an increase of 10% compared to 20 years ago.
Australia, Canada, Ireland, New Zealand, UK and the US are home to 20% of the world's obese people.
Over the last 30 years Australians have increased their energy consumption. At the same time, they have reduced their energy needs because they are not so physically active.
