To provide a simple projection of COPD mortality from SFU, consider a scenario in which age-specific COPD death rates (per 1000 population in age group) are constant over time. 6 Using World Bank country demographic projections, we can apply the relative risks of COPD from SFU in Desai et al (2004) to estimate COPD mortality by SFU prevalence rates in 50 years from now. The results are presented for China, India, Nigeria and Tanzania in tables . COPD mortality from SFU would be higher in 2055 than today in all four countries at SFU prevalence rates .
