Previous studies have shown that children with a history of BPD have impaired lung function in childhood compared to their term counterparts. However, little is known about potential modifiable factors that alter lung function trajectories and subsequent respiratory morbidity in this population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>To identify potential modifiable risk factors for the development of impaired lung function in patients with a history of prematurity and bronchopulmonary dysplasia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Growth parameters (birth, 2 years old, 6 years old) and pulmonary function testing (6 years old) were retrospectively reviewed for subjects (<jats:italic>n<\/jats:italic>\u2009=\u2009598) recruited from an outpatient BPD clinic who were born \u226436 weeks gestation and were\u00a0\u22655 years of age.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 598 recruited subjects, 88 (14.7%) performed adequate pulmonary function testing at approximately 6 years of age.

Although growth parameters at age 2 and 6 years did not correlate with lung function values at 6 years of age; use and greater requirement for supplemental oxygen and the presence of a Nissen fundoplication at discharge were associated with lower lung function. Prospective studies should focus on identifying modifiable risk factors that could minimize the impact of BPD on later lung
