I don't know of any studies looking specifically at smoking vs non-smoking, but its been highly speculated to be a strong risk factor. Apparently, there is a big gap in prevalence of smoking between men and women in China (close 50% for men, closer to 5% for women), which is thought to be at least partially an explanation for the differences in deaths (2/3rds of deaths were male, 1/3 were female). |
