A study at the University of Minnesota found that female smokers had a 25-per-cent greater risk of coronary heart disease than male smokers.

More specifically, the study found that the difference in the risk of developing heart disease increased by 2 per cent each year women smoked.
The research, which reviewed cases between 1966 and 2010 on 2.4 million people, was published in the medical journal The Lancet.
The State Column reportst that it remains unclear if the underlying mechanism of the sex difference is biological or potentially related to smoking behavior between men and women. Researcher are still working on figuring out what to make of this observation, analysing data on over 4 million people across different studies. (pi)
