Smoking as a risk factor in the health of women.

It is estimated that more than 200 million women smoke worldwide. It is also estimated that if current smoking rates among men and women persist worldwide, by 2025, 9% of the world's deaths and disabilities will be related to tobacco use. Smoking is associated with an increased risk of cardiovascular disease, cancer (lung, cervix, pancreas, kidney, bladder, esophagus, pharynx), pulmonary disorders, cerebrovascular disease, and many other health risks. Smoking also adversely affects fertility and reproductive outcomes. Although a greater percentage of women smoke in developed than in developing countries, women in developing countries appear to be initiating smoking habits in increasing numbers. If current trends persist, the adverse effects of smoking on women's health clearly will continue to escalate.
