Women who were exposed to secondhand smoke while growing up may be more likely to miscarry, according to a recent study conducted in China.
Apparently, nonsmoking women who lived with multiple smokers during childhood had a 20% greater risk of miscarriage than those who grew up with only other nonsmokers in their homes.
”Our findings support the enactment of stringent national smoke-free laws and strict enforcement in China, and promotion of smoke-free homes to protect children, as well as the need for campaigns to change social norms of smoking and passive smoking”, researchers say.
The study analyzed data from more than 20,000 women over age 50 and was published in the journal Tobacco Control.
There are still a few things that are pretty unclear about the study that attracted some doubt about its credibility. The study is entirely focused on Chinese women living in China, and it also relies largely on these women’s memories. Moreover, the scientists had no way of determining how much secondhand smoke the women were exposed to in day-to-day life during their pregnancies.
