Prevalence and Impact of COPD

  • At present, nationally, COPD affects 3.9 per cent of men and 4.8 per cent of women.
  • The Canadian Lung Association (2008) suggests that COPD affects an estimated 1.5 million Canadians. They further suggest that 1.6 million Canadians 40 years or older may currently have undiagnosed COPD; thus, in excess of three million Canadians may be living with COPD.
