Here’s yet another reason to kick the habit. According to a new study, women have a 25% higher risk of developing coronary heart disease conferred by smoking in comparison with men.
Researchers at the University of Minnesota and Johns Hopkins University did a meta-analysis of data including about four million people and 67,000 coronary heart disease events from 86 studies. They discovered that in 75 cohorts (total 2-4 million participants) that adjusted for cardiovascular risk factors aside from coronary heart disease, the combined adjusted female-to-male relative risk ratio (RRR) of smoking in comparison with not smoking for coronary disease was 1-25, in other words 25% higher for women. They found the RRR increased by two percent for every year of follow-up, meaning that the longer a woman smokes, the risk of developing coronary heart disease is higher compared to a man that has smoked the same length of time.
The authors of the study suggest cigarette toxins may have a more powerful effect on women and the increased risk may be due to physiological differences between the sexes.
