Why Americans die younger than Brits. And Canucks, Aussies and Japanese...

"It's smoking, obesity and access to health care," say the Ministry of the Bleedin' Obvious.

Why do Americans die younger than Britons?

New life expectancy figures show Americans some way behind countries like Canada, the UK and Australia. Why?

Living in the world's richest country comes at a price, and it's measured in life years.

Men in the US are on average aged 75 when they die. That is 1.5 years younger than men in the UK and 3.5 years younger than men in Australia, says a new study.

American women live on average to just under 81 - about three years younger than the average Australian woman.

While life expectancy in the US continues to improve, says the report by researchers at University of Washington in Seattle and Imperial College, London, it is not increasing as quickly as in other Western countries, so the gap is widening.

"The researchers suggest that the relatively low life expectancies in the US cannot be explained by the size of the nation, racial diversity, or economics," says the document, which ranks the US 38th in the world for life expectancy overall.

"Instead, the authors point to high rates of obesity, tobacco use and other preventable risk factors for an early death as the leading drivers of the gap between the US and other nations."

"We weren't surprised that we had lower life expectancies than other countries, but we were surprised by the fact that we were falling further behind," says Dr Ali Mokdad, professor of global health at the Institute for Health Metrics and Evaluation at the University of Washington.

Take a country like Australia, he says. "It also has a nation of immigrants. It also is a relatively young country. It has similar socioeconomic characteristics.

"It has an obesity problem, and yet it has continued to improve in life expectancy and remains one of the healthiest nations in the world."

So how should the US address these risk factors?

Smoking alone is responsible for one out of every five deaths in the US, the professor says, yet the US has not been as tough as Australia in restricting tobacco advertising and public smoking.

Australia also has a greater focus on primary care - which helps with health education, and early treatment of any problems - and it has done a good job reducing the number of road traffic accidents, he adds.

The US could also save 100,000 lives a year by reducing salt in people's diets, since high blood pressure kills one in six people, Dr Mokdad says.

"We have high rates of poverty and high rates of uninsured or people lacking access to care. We have fewer primary care providers and fewer physicians per person than most states. And high rates of low education.

"We have the highest rate of obesity in the country and therefore one of the highest rates of diabetes. A relatively high rate of tobacco use and high rates of cardiovascular disease, stroke and cancer.

Then there's the big issue - about one in three adults is classified as obese. That's about 10 times as many as in long-living countries like Japan, according to OECD figures.

But the US is a big country, and while parts of Mississippi have a male life expectancy of 67, behind nations like the Philippines, women in areas of Florida live as long, on average, as the Japanese, who top the longevity rankings.

It is precisely this kind of inequality that goes some way to explain why the US - and the UK to a lesser degree - lag behind other countries, according to Danny Dorling, a professor of human geography at the University of Sheffield in the UK.

He believes a more even distribution of wealth, even if the average were lower, could mean longer lives for everyone.

"I think stress is a part of it - this is the key thesis of Michael Marmot and his book on the status syndrome. People get worn out faster with greater inequality.

"However there is much more. If you have most health spending just going on a few people who have the best health to begin with - [as in] the US system - that is hardly efficient.

"In a more unequal rich country more doctors are working on things like plastic surgery. More dentists whiten teeth than fix bad teeth and so on."

While it is not surprising that poor Americans lose out from inequality, Prof Dorling argues that the rich may suffer too.

"Top income groups are badly affected because their doctors are not necessarily mainly interested in their health but work for organisations that have to make an income," he says.

"I am not suggesting it is deliberate but you make more money out of a patient who spends more on many drugs and investigatory operations than one who lives longer with less intervention.

"In a more equal system the rich who are well get less intervention - and they live longer in the UK than the US."

Growing income inequality in the UK, since the 1970s, has has helped to push it down the European life expectancy rankings, says Mr Dorling.

However, life expectancy is not just about forecasts made for newborn babies.

When you look at life expectancy at 65, the US does perform well, says Svetlana Ukraintseva, research scientist at the Center for Population Health and Aging (CPHA) at Duke University in North Carolina.

Elderly Americans have a higher chance of surviving heart disease and many cancers than their counterparts in other rich countries, she says. Where the US lags behind is what happens at a much younger age. Infant mortality rates are high, she points out.

"So it's not the medical system itself that is the problem but access to it," she says.

"Medical insurance for all might help."

This is one goal of the healthcare reform signed into law in March 2010, which will oblige American adults to have health insurance when it comes into force in 2014.

However, this remains a controversial idea in the US and the legislation could yet come unstuck.

Challenges to the constitutionality of the law are working their way through the courts, and fierce opponents in the Republican Party make no secret of their desire to repeal the legislation if the opportunity arises.

I don't know about the other factors but Americans smoke way less than the Brits

"I think stress is a part of it -"

Goddamned right it is.

I don't know about the other factors but Americans smoke way less than the Brits

According to this 2009 survey, the US ranks much higher in this table of average number of cigarettes smoked per adult per year. http://markosun.wordpress.com/2009/12/13/smoking-rates-by-country/

The most recent statistics I can find have the percentage of UK adults who smoke at 21% (2009) and US adults at 20% (2010) so barely different, but it seems those who smoke in the US, smoke more.

Dying younger is a good thing.  Remember, anything past 65 are the useless years.

I feel like I'm being nagged at.

Having recently been to Disneyland there are two observations:

1) There are a lot of really really fat people at Disneyland.  It may be that Disneyland is a magnet for fat people.  I hope that is true.  I would hate to think the American public has the same percentage of really fat people.

2) Serving sizes.  I know we have gone over this before but wow are the serving sizes at restaurants around the Disney are large.  Now it may be that portions have to be large because a lot of fat people go to Disneyland.

Americans are just fat all around, CC.

Take a trip to Burger King in Washington state, if its anything like New York State, the amount of food you can get for 20$ is staggering.

They have food at Burger King?

Relieved at being released from your earthly suffering?

Nah, fat people don't typically like to spend their days walking around.

There was a lot of fat people taking scooters around.  Sad sight seeing obese parents on scooters with their young kids (on the way to becoming really fat) trailing behing them.

Person years is not a great metric. Pound years makes more sense I think. Americans may die earlier but there's more of a typical American than a typical anything else. So what if a Japanese woman gets to 95 if she's just 50 lbs?
