Asthma

Respiratory diseases are among the leading causes of morbidity and mortality in many countries. Chronic obstructive pulmonary disease (COPD) is the most common respiratory cause of death and is mostly attributable to smoking. The mortality trend for COPD is of particular interest because, in the United States, and probably in other countries, trends are upward in contrast to sharply downward trends for heart disease, stroke, and other chronic diseases. Assessment of international differentials in levels and trends for COPD has been complicated, however, not only by intercountry differences in cause-of-death classification and coding practices, but also by revisions of the International Classification of Diseases which the World Health Organization uses to collect and report mortality statistics. This article compares re­cent mortality trends for COPD and the related condition, asthma, in France, the United States (US) and Canada addressing these complicating factors and the possible role of cigarette smoking in the mortality differentials. Information is provided for ages 55 to 84 where mortality from COPD is common. viagra plus
