Smoking and exposure to second smoke can trigger early menopause and infertility in women, revealed a new study.
A recent study published in the Journal Tobacco Control analyzed the data of 160,000 healthy postmenopausal women. The study was led by Dr. Andrew Hyland, chair of health behavior at Roswell Park Cancer Institute, NewYork.
‘Active smoking in women increases the risk of early menopause by 14% and infertility by 26% whereas passive smoking increases the risk of both by 18%.’
AdvertisementResearchers looked at the age of menopause and fertility, along with tobacco exposure in these women. The onset of menopause and fertility issues were also evaluated in them. They found that both smoking and exposure to secondhand smoke were linked to fertility issues and early menopause.
Hyland pointed out that smokers were 14 percent more likely to be infertile and 26 percent more likely to have early menopause compared to non-smokers. While non-smokers exposed to secondhand smoke were 18 percent more likely to have fertility problems and early menopause.
Women who smoked reached menopause about 22 months earlier compared to women who did not smoke. Also, those who were exposed to the highest level of passive smoke reached menopause 13 months earlier than those who were not exposed.
Hyland added, "This is an observational study looking at data already collected. It [the link] could be something associated with early development and exposure as a young child."
