Data Sources
Data were obtained for the period from 1980 to 1995 with the cooperation of the Health Statistics Division of Statistics Canada. The data supplied included the prevalence, mortality, and hospital morbidity from COPD.
Prevalence: Estimates of the point prevalence of COPD were derived from the 1994–1995 National Population Health Survey conducted by Statistics Canada.11 The target population of this survey included household residents in all provinces, with the principal exclusion of the
Prevalence of COPD
The household survey estimated that almost three quarters of a million (749,714) Canadians had chronic bronchitis or emphysema diagnosed by a health professional. Prevalence rates according to gender and age-groups are presented in Table 2. In each of the three major age categories, the prevalence of COPD was higher among men than among women. For the population as a whole, the prevalence increased with age, the highest prevalence being recorded among men > 75 years old.
COPD-Related Mortality
In 1980, COPD accounted
Discussion
Changes in clinical practice and disease classification make it important to understand the real changes in prevalence, mortality, and morbidity from COPD. Comparison with similar information from other countries is hampered both by the updating of the ICD (now in its ninth version) and by the inclusion of asthma (ICD-9, code 493) in many reports of COPD.916 In order to obtain a clearer picture of the impact of COPD, we excluded from the analysis those with a diagnosis of asthma.
Conclusion
This survey suggests that COPD remains an important condition among Canadians and will likely continue to be for many years to come. Primary prevention among teenagers through strong media campaigns is most likely to influence the trends in the epidemiology of the disease. However, detailing the potential long-term health consequences of smoking (such as lung cancer and emphysema) is one of the least effective strategies that has been used in antismoking advertising campaigns, especially with
