A new study has found that a minimum height threshold of 3.9 metres (12 feet) is the maximum height that can be legally reached in Australia, with the maximum at 6.9 meters (22 feet).
The Australian Bureau of Statistics said the research showed that the average person with a height of 3 metres (10 feet) or greater has an average of an extra 7.8 years in their life.
The findings come as the number of Australians in their early 30s is set to surge by 50 per cent over the next decade.
The report from the Australian Bureau for Statistics found that the proportion of people between the ages of 30 and 44 who are taller than 3.4 metres (9 feet) has nearly doubled to nearly 14 per cent of the population.
The report found that there was a significant number of people in their mid-30s who were 5 metres (16 feet) and above, but the proportion was still just under 10 per cent.
“The increase in height is most pronounced in people between 30 and 45 years of age,” the report said.
The research showed there was also a significant increase in the height of people under the age of 30.
The new findings, published in the Journal of Health Psychology, are based on a survey of 2,988 people aged 15 and over who had measured themselves before the age 30.
Researchers used a scale to measure the height at which they were considered to be an average person, and then calculated the percentage of people who had reached the same height as them.
The results showed that for those between the age 15 and 30, about 17 per cent had reached a height 3.3 metres or greater.
By comparison, the proportion for people over the age 40 was about 15 per cent, while for people under 30, it was only about 9 per cent and for people aged between 15 and 19, it only about 4 per cent.(Reuters: Chris McGrath)The study found that between 30 per cent to 45 per cent are considered to have an average height of 5.4 or greater, while there was an even higher proportion of the people in this age group reaching heights between 5.3 and 5.5 metres.
“These data suggest that there are many people in the population who are not tall but are significantly taller than others,” Dr Rishi Vatsa, one of the researchers from the University of Western Australia, said in a statement.
“This suggests that a higher threshold of 6.3 meters may be necessary for individuals with average height.”
Dr Vatsas work also involved analysing data on people’s height and health, as well as their own body weight.
Dr Vatas said the study revealed “how much taller we are and how much taller our bodyweight is, and that may be the difference between being fit and not being fit.”
The study also found that people who were taller than average had a higher rate of diabetes and heart disease.
Dr Rishi also said that the study showed that there is a “large disparity” between people with a physical disability such as a spinal problem and those without.
The researchers found that only about 1 in 20 people in Australia are classified as having a physical condition that requires assistance, and they found that more than 60 per cent said they were in poor physical health.
Dr Michael Smith, from the Royal Australian and New Zealand College of Surgeons, said it was “unacceptable” that the Australian population was getting taller.
“We know that obesity is a problem and there are a lot of factors associated with it and people are not doing enough to reduce it,” he said.
“It is an epidemic in our country, and it has become a huge problem, not only in Australia but globally.”
That is why it is so important that we are working with other countries to reduce the size of our population.
“There is an opportunity for us to work with other health systems, including the US, and we need to take advantage of the new technology that is coming out of this country.”
The ABS said the data on height in Australia comes from data collected by the Australian Institute of Health and Welfare (AIHW), which measures height and weight based on information collected by local health departments.
Dr Smith said there was no evidence that the rise in height was caused by an increase in people living longer, adding that “we know that the obesity epidemic is not caused by people living in a shorter life span”.
“If anything, it is probably due to the increase in lifestyle and exercise choices, including obesity,” he added.
“Our findings show that the number and proportion of Australians who are at or above the Australian height threshold has increased.”
Dr Smith added that people in more healthy lifestyles would be able to achieve the same heights.
“In the longer term, there are ways to reduce your risk of developing diabetes and cardiovascular disease and heart diseases.
But for now, the data shows that
