《中英對照讀新聞》Smoking linked to earlier menopause 抽菸讓更年期提早


Women who smoke may hit menopause about a year earlier than those who don’t light up, according to a new look at past research. That’s important because the age at which women stop getting their periods may influence their risk of bone and heart diseases as well as breast cancer.


Study author Volodymyr Dvornyk, from the University of Hong Kong, said that women should be aware of this effect and possible health consequences of smoking, in addition to its other known risks. He and his colleagues scanned the literature and found that women who were current smokers hit menopause a year earlier, on average, than non-smokers.


That data came from six studies including about 6,000 women in the U.S., Poland, Turkey and Iran. Non-smokers hit menopause between age 46 and 51, on average, depending on the study population. In all but two of the studies, smokers were younger -- between 43 and 50, overall.


Dvornyk and his colleagues also analyzed five other studies that used a cutoff age of 50 or 51 to group women into "early" and "late" menopause. Out of more than 43,000 women in that analysis, women who smoked were 43 percent more likely than nonsmokers to have early menopause.
