Calculating gambling odds and lung ages for smokers
European Respiratory Journal , 09/30/09

Hansen JE et al. – Using odds and physiological lung age ages rather than traditional 95% confidence limits might better persuade smokers to quit.

Exclusive Author Commentary
J.E. Hansen, 09/30/09

It is difficult for smokers to stop their addiction. FEV1/FVC and FEV1/FEV6 normally decrease with increasing age. These ratios decrease faster in MOST smokers, but often not enough in a decade or two to be below the 95% confidence limits and interpreted as “abnormal”. However, this faster decrease in FEV1/FVC or FEV1/FEV6 is not really normal and can be interpreted as an increase in physiological lung age. To use, find the predicted and actual %FEV1/FEV6 or %FEV1/FVC from any spirometry report. For every single percent that the actual ratio is below mean predicted ratio, physiological lung age increases 4 years more than actual age for %FEV1/FEV6 and 3 years more than actual age for %FEV1/FVC. Use this information plus support groups and pharmacotherapy to help motivate adult smokers to quit. Not many adults wish to age faster. Share your experience. Thanks.
