Pregnancy Can Make You Age Faster

Pregnancy is a wonder of biology, but new research shows that feat may come at a price. In a study published in Proceedings of the National Academy of Sciences, scientists found that women who have been pregnant showed more signs of biological aging compared to women who had never been pregnant before. The more times a woman had been pregnant, the faster her rate of biological aging. “We’re learning that pregnancy has long-term effects on the body,” says Calen Ryan, associate research scientist at the Columbia University Aging Center at the Mailman School of Public Health. “They are not all bad, but it seems to increase the risk of some diseases and all-cause mortality.” [time-brightcove not-tgx=”true”] The study Ryan and his team analyzed data from more than 1,700 people in the Philippines who were part of the Cebu Longitudinal Health and Nutrition Survey. The participants, who were all ages 20 to 22 back in 2005 when the study began, provided blood samples and answered questions about their reproductive and sexual history, including how many times they had been pregnant and whether or not those pregnancies had resulted in live births. A smaller group of women provided additional blood samples from 2009 to 2014 to let researchers compare changes over time.
