New Delhi: Being blessed with a child is considered a blessing, but a study has claimed that childbirth may shorten women's life expectancy by as much as 11 years.

The US study, conducted by a team of researchers from the George Mason University, said that women who have given birth have shorter telomeres compared to women who have not given birth.

Telomeres are the end caps of DNA on our chromosomes, which help in DNA replication and get shorter over time.

While previous studies have associated the length of telomeres with morbidity and mortality, researchers said that this is the first study to examine links with having children.

The study, published in the journal Human Reproduction, found that telomeres among women who had children were the equivalent of 11 years shorter.

This was a larger change than has been reported by other research groups for smoking or obesity.

"We can't tell if having children is related to shortening of telomeres or merely whether women who have children start out with shorter telomeres," said Anna Z Pollack, from George Mason University.

"Additional factors to consider include stress and social support, as well as whether similar findings are seen in men," Pollack said.

The findings are preliminary and should be confirmed with prospective studies, she said.
