Unemployed men ‘show signs of faster ageing'

Men who remain jobless for more than two years show signs of faster genetic ageing

Scientists made the discovery after examining a genetic marker of biological ageing in DNA samples from 5,620 Finnish men and women.

They focused on telomeres, caps on the ends of chromosomes that perform a similar role to the plastic ends of shoelaces, by preventing DNA becoming frayed and degraded.

Telomeres shorten as cells divide, eventually ceasing to function. They shorten at different rates for different individuals, and short telomeres are linked to age-related conditions such as type-2 diabetes and heart disease.

British and Finnish scientists looked at telomere length in blood cell samples collected in 1997, when all the participants were 31 years old.

Men who had been unemployed for more than two of the preceding three years were more than twice as likely to have short telomeres as men who were continuously employed.

The trend was not seen in women, but fewer women than men in the study had been unemployed for long periods.

Jessica Buxton, from Imperial College London, who co-led the research reported in the online journal Public Library of Science ONE, said: “Shorter telomeres are linked to higher risk of various age-related diseases and earlier death. Stressful life experiences in childhood and adulthood have previously been linked to accelerated telomere shortening. We have now shown that long-term unemployment may cause premature ageing too.”

Co-author Leena Ala-Mursula, from the University of Oulu in Finland, said: “There has been lots of research linking long-term unemployment with ill health.

“These findings raise concerns about the long-term effects of joblessness in early adulthood. Keeping people in work should be an essential part of general health promotion.”
