This was a cohort study of 201 consecutive ELBW\/EPT survivors born in the state of Victoria during 1997, and 199 contemporaneous randomly selected NBW\/term controls. Respiratory function was measured at 8 years of age according to standard guidelines, and compared with previous cohorts born in 1991\u20131992. Respiratory function data were available for almost 75% of both cohorts. ELBW\/EPT subjects had substantial reductions in airflow compared with controls (e.g., mean difference in forced expiratory volume in 1\u2009sec [FEV<jats:sub>1<\/jats:sub>] \u22120.91 SD, 95% confidence interval [CI] \u22121.19 to \u22120.63 SD, and in maximum expiratory flow between 25% and 75% of vital capacity [FEF<jats:sub>25\u201375%<\/jats:sub>] \u22120.96 SD, 95% CI \u22121.22 to \u22120.71). These differences were similar to those observed between ELBW\/EPT and controls subjects born in 1991\u20131992. Within the ELBW\/EPT cohort, children who had BPD in the newborn period had significant reductions in both the FEV<jats:sub>1<\/jats:sub> (\u22120.76 SD) and FEF<jats:sub>25\u201375%<\/jats:sub> (\u22120.58 SD) compared with those who did not have BPD, which were not statistically significant from those in the 1991\u201392 cohort. ELBW\/EPT children born in 1997 still have significantly abnormal lung function compared with NBW\/term controls, but results were similar to an earlier era when survival rates were lower.
