Residents in the European Union's wealthier nations live in good health up to 14 years longer than their more recent EU neighbours to the east, according to a major study published Monday.
European nations averaging the fewest "healthy life years" -- time lived without disability or limitations on activity after the age of 50 -- face serious challenges in containing health care costs, the study concluded.
They will also be hard put to achieve EU targets of raising the employment rate among 55 to 64 year olds to 50 percent by 2010, the researchers found.
Life expectancy in Europe has been steadily climbing, and reached an average of 78.6 years for men who were 50 in 2005, and 83.5 years for women.
The gap between nations with the shortest and longest average lifespan was 9.1 years for men (71.3 in Lativa compared to 80.4 in Italy), and a narrower 6.1 years for women (79.3 in Latvia and 85.4 in France).
What has remained unclear, however, was how many of these added years were spent in good -- and potentially productive -- health.
Sifting though national and European statistics, a team of researchers led by Carol Jagger at the University of Leicester in Britain found huge gaps across the continent.
On average, a 50-year-old man from Italy, The Netherlands, Sweden or Malta will live well past 70 without disability or the need to limit his activities -- ten extra years of healthy life compared to his neighbours in Hungary, Latvia, Slovakia and Lithuania.
