Approximately 10% of all children worldwide are born preterm and respiratory consequences are amongst the most common sequelae of preterm birth. Except for a higher prevalence of respiratory symptoms and hospital admissions, preterm birth is associated with lower lung function that may track into adulthood. Lung function impairment is not restricted to extreme or very preterm-born subjects as also children born moderate-late preterm have lower Z-scores for lung function. Given the heterogeneity of prematurity-associated lung disease, phenotype-based, multidisciplinary management is needed to improve respiratory health in preterm-born subjects.
