Global lung health: the dangers of mild lung function impairment

Abstract

The relationship between low lung function and increased mortality risk, especially in the context of ageing and exposure to noxious particles and gases, was established several decades ago. However, it was not until recently that low peak lung function in early adulthood (and thus the vital lung function trajectory that followed, independently of the ageing process) was associated with an increased prevalence, and about a decade earlier incidence, of respiratory and cardiovascular abnormalities, as well as premature death.
