Increasing evidence for gender differences in chronic obstructive pulmonary disease.

The prevalence of chronic obstructive pulmonary disease (COPD) among women is increasing and differences in both the management of COPD and the results of treatment between men and women have been noted. This article investigates the reasons for this increase in prevalence and the differences in natural history and COPD management between male and female patients. The main reason for the rise in prevalence of COPD in women is increased tobacco use. An additional factor is the greater susceptibility of women to damage from smoke and air pollution. The health-related quality of life is worse in women when compared with men with the same severity of disease. In addition, nutritional status is often worse in women. The most important treatment for COPD is to stop smoking. Women appear to be more dependent on cigarettes than men, and have greater difficulties stopping smoking, especially when they live with a partner who smokes. Rehabilitation is an effective treatment for both male and female COPD patients, but the focus is different: women need more emotional support and social interaction to achieve the best results.
