In themeantime, women hoping to get pregnant may want to watch theirweight. “For every one unit increase in BMI, the babies’telomeres shorten by 0.5 per cent,” saysat the University of Birmingham, UK.“Maintaining a healthy body weight whilst trying to conceive willhave long-term benefits for the baby, giving it a head start withlonger telomeres,” she says.

“It’s alarge, significant difference,” says Nawrot. “In normal ageing, ittakes 5 to 10 years to experience a shortening of 5.5 percent.”

How wouldweight affect telomeres? Nawrot’s team thinksexcess fat tissue could be to blame. Fat can trigger inflammation,and produce reactive chemicals that cause oxidative stress, whichcan damage cells and shorten telomeres. These could cross into ababy’s body via the placenta, they suggest.

There is noknowing whether babies born to obese mothers will live 5 years lessthan other babies. “We can’t make a prediction,” says Nawrot. “Wewould need to conduct longer term studies, and follow thesebabies.”

关注体重

Ourbiological age is linked to the– bits of DNA that cap the endsof our chromosomes. Our telomeres shrink every time our cellsdivide, and continue to shorten throughout life. “Short telomereshave been associated with, type 2 diabetes and atherosclerosis,”saysat Hasselt University inBelgium.

Watchyour weight

If that isthe case, a father’s weight could play a role, too, says Henriques.“Just like for the mother, if the father’s BMI is higher, it maymean that his telomeres are shorter to start with, which couldinfluence telomere length in the child,” she says. “This would needto be tested, though.”

正常体重对于一位孕妇以及她未来的宝宝来说是最重要的。Overweightmothers give birth to biologically older babies译Women who areoverweight while pregnant are more likely to have babies who arebiologically older than those born to women of a healthy weight.This could put the babies at a higher risk of developing chronicdiseases later in life, and may reduce their lifeexpectancy.

体重对端粒会造成怎样的影响呢?纳罗特的研究小组认为,她们有可能通过基因将此特性传递给孩子,英国谢菲尔德大学的卡特琳娜·亨利克斯对此不太确定。她说:超重的人可能已经拥有较短的端粒了, 但是, The teamfound that a woman’s BMI seems to have a significant effect on thetelomere length of her baby. The telomeres of babies born tooverweight women were around 2.5 per cent shorter than those whosemothers were a healthy weight, while those born to obese women hadtelomeres 5.5 per cent shorter than the babies of mothers with ahealthy BMI.

The length ofa person’s telomeres at birth varies, though it is not clear why.Nawrot and his colleagues wondered if having an overweightormothermight make a difference. The team collected the BMI scores of 743women who later went on to become pregnant. When the women hadbabies, they took samples of blood from the umbilical cord andplacenta, and measured the length of telomeres in bloodcells.

Butat the University of Sheffield, UK,isn’t so sure. Overweight people may already have shortertelomeres, something they may pass on to their children via theirgenes, rather than through the placenta, she says.
