Women exposed to second-hand smoke from their parents while growing up are more likely to suffer miscarriages as adults, according to a new study appearing in the American Journal of Epidemiology.
The study examined nearly 2,200 non-smoking pregnant women. Researchers found that women exposed to their parents' secondhand smoke during childhood were 80 percent more likely to have a miscarriage compared with women whose parents were nonsmokers, according to a report in the Daily Telegraph.
It's known that parents' smoking can harm developing fetuses and children, contributing to early-life problems like low birth weights and asthma, the study said.
But this is the first study to show a link between childhood exposure to parents' smoking and reproductive ability in adulthood, according to lead author Dr. John Meeker, University of Michigan School of Public Health, and associates.
More research is needed to confirm the finding, Meeker, an assistant professor of environmental health sciences, told Reuters Health.
