Ichiro Kawachi of the Havard School of Public Health studied the effect
of passive smoking with respect to cardiac disease and
followed 32046 healthy, non-smoking women enrolled in the nurses health study
for a period of 10 years (Circulation
1997;95:2374-9). He found that healthy, non-smoking
women who reported regular exposure to passive smoke at home or in the workplace
had a 91% greater relative risk of heart attack than those who reported minimal
passive smoke exposure. Those who reported occasional exposure had a 58% greater
relative risk.
And...
Japanese researchers in 2007 have discovered that, women married to men who smoke at home double their risk of
adenocarcinoma, a common type of small-cell lung cancer that accounts
for 70 percent of female lung-cancer cases.
According to Yomiuri Shimbun
reported Dec. 13, 2007 that researchers from Japan's Health, Labor and
Welfare Ministry studied 28,000 nonsmoking women ages 40 to 69 and found
that those with husbands who smoked at home were twice as likely to get
lung cancer as those with nonsmoking spouses.
The risk was 1.7 times higher for women married to men who smoked
less than 20 cigarettes per day, and 2.2 times higher for those married
to smokers who consumed more than 20 cigarettes daily.
The researchers estimated that 40 percent of the women studied would
not have developed cancer if they had not been exposed to tobacco smoke
at home.
Do I need to say more?
