Chronic obstructive pulmonary disease (COPD) prevalence has been thoroughly investigated, particularly in Western Europe and North America. Few of these data are directly comparable because of survey discrepancies in the mix of research populations, disease diagnosis standards, and risk factor definitions. Few community studies have explored COPD phenotypes and incorporated methods of characterizing the illness other than spirometry.
