London - "Alarming" rates of smoking, alcohol consumption and obesity in Europe could set back progress in reducing premature mortality, the World Health Organization said Wednesday in a report on the region's health.
While Europeans are living longer than ever before, there remain "unacceptably high" differences in life expectancy between countries, with an 11-year gap between the highest and lowest, the report also said.
The first study of its kind for three years, the report covers 39 countries including European Union member states as well as former Soviet republics.
Levels of premature mortality from noncommunicable diseases (NCDs) -- including cancer, cardiovascular diseases, diabetes and chronic respiratory diseases -- are decreasing "quickly", the report said.
But levels of alcohol consumption, tobacco use and obesity remain "alarmingly high" and this "could mean that this progress is not maintained,", it said.
"Europeans live long lives and healthy lives. We are the longest living region in the world," said Claudia Stein, a senior WHO director for Europe.
But "the differences in health status between European countries are... inexplicably wide."
"If rates of smoking and alcohol consumption and obesity do not decline we may risk the gains in life expectancy we have seen -- which may mean that the next generation may lead shorter lives than that we do."
World's biggest drinkers
Although rates of smoking and alcohol consumption are declining in many parts of the continent, Europeans still smoke and drink more than people anywhere else in the world, according to the WHO.
It estimates that on average 11 litres of pure alcohol are drunk per person each year, while 30 percent of the population uses tobacco.
Meanwhile obesity is increasing, with 59 percent of Europe's population either overweight or obese, ranking only slightly behind the Americas which have the highest rates in the world.
looked at progress made towards the WHO's "Health 2020" targets.
Average life expectancy for men and women ranges from 71 in Belarus, Moldova and Russiato 82 for countries like France, Italy and Spainaccording to the latest figures from 2011.
The gap represents a fall of three years since 2009 and Europe is "on track" to exceed targets to reduce premature mortality from NCDs by at least 1.5 percent a year by 2020, the report said.
But Stein said that there could be a "flattening off of the curve" affecting the next generation's life expectancy, if lifestyle risk factors are not addressed.
'War' on obesity
"Smoking rates are going down everywhere -- we have very few exceptions -- but obesity is increasing and one does not offset the other," Stein told AFP.
"What we do not want to see is that we are winning the war against alcohol and smoking but losing the war against obesity."
She said there were also "unacceptable" health inequalities to tackle.
Infant mortality has fallen to an all-time low but there remains a 10-fold difference between the highest and lowest countries, with 22 deaths per 1,000 births in Kyrgyzstan compared to two in Finland.
"The differences between countries in life expectancy and mortality are shrinking. But the differences are still there and some of them are extreme," Stein said.
This year's report also looked for the first time at the impact of "life satisfaction" on life expectancy.
Denmark, Finland, Sweden and Switzerland -- the four countries reporting the most "life satisfaction" according to polling data collected by Gallup -- also have some of Europe's highest life expectancy rates.
