The Australian Bureau of Statistics has released the first results from the most comprehensive study of the health of Australians ever undertaken.

Since March last year, the Australian Health Survey has weighed, measured, interviewed and taken biomedical samples of around 50,000 people.

The study has found that obesity rates in adults are continuing to grow and 63 per cent of Australians are now classed as overweight or obese.

Researchers also found 67 per cent of Australians perform little to no exercise.

The number of people smoking is in decline, but 2.8 million people still continue to smoke every day.

Arthritis was the most common long-term health condition with more than 3 million Australians suffering from the condition, followed closely by the 3 million people who deal with a mental or behavioural condition each day.

The research found the number of adults having more than two standard drinks a day had dropped to 19.5 per cent from 20.9 per cent.

When it came to healthy eating habits, the research found only 5.6 per cent of Australian adults had an adequate daily intake of fruit and vegetables.

That number sky-rocketed to 95 per cent to children under 11.

The ABS defined a serve of vegies as half a cup of cooked vegetables or a potato, and a serve of fruit as one medium piece of fruit.

The average measurements for Australians increased, with the average man weighing 85.9 kilograms and the average woman 71.1 kilograms.

However, the rate of overweight and obese children aged between 5-17 remained stable at 25.3 per cent.

The average man was 175.6 centimetres tall and the average woman was 161.8 centimetres tall.
