The association between living below the relative poverty line and the prevalence of chronic obstructive pulmonary disease

摘要

BackgroundBecause poverty is a multifaceted concept with a complex definition, this concept may not be useful when formulating economic policy. Thus, most governments use the relative poverty line to identify poor participants who may receive economic support. The aim of this study was to investigate the association between living below the relative poverty line and the prevalence of chronic obstructive pulmonary disease (COPD).
