Asthma is the most common chronic disease of childhood, while chronic obstructive pulmonary disease (COPD) is a leading cause of death in the world. COPD is the only major cause of death that is increasing in frequency, a phenomenon attributed to tobacco abuse. The prevalence has been stable in men, whereas the prevalence in women has doubled in the past few decades and women now account for >50% of COPD-related deaths.
