LONDON, England / The Guardian / Society / Smoking / August 11, 2011
Huge US study published in the Lancet finds risk of heart disease linked to smoking is 25% higher for women, reports Press Association.
Smoking is more likely to give women heart disease than men, a study has found. Toxic chemicals in tobacco smoke may have a more potent effect on women due to biological differences, scientists believe. US researchers analysed pooled data on around 4 million individuals from 86 studies. After adjusting for other risk factors, they found the increased risk of heart disease linked to smoking was 25% higher for women.
The longer a woman smoked, the greater her heart disease risk was compared with that of a man who had smoked for the same length of time. A woman's extra risk increased by 2% for every additional year she had been smoking.
