BACKGROUND: Increasing evidence suggests that preterm birth affects later lung function. We systematically reviewed the literature to determine whether percentage predicted forced expiratory volume in 1 s (%FEV1) is lower in later life in preterm-born subjects, with or without bronchopulmonary dysplasia (BPD), compared with term-born controls. METHODS: Studies reporting %FEV1, with or without a term-born control group, in later life for preterm-born subjects (<37 weeks gestation) were extracted from eight databases. Data were analysed using Review Manager and STATA. The quality of the studies was assessed. RESULTS: From 8839 titles, 1124 full articles were screened and 59 were included: 28 studied preterm-born children without BPD, 24 with BPD28 (supplemental oxygen dependency at 28 days), 15 with BPD36 (supplemental oxygen dependency 36 weeks postmenstrual age) and 34 born preterm. For the preterm-born group without BPD and for the BPD28 and BPD36 groups the mean differences (and 95% CIs) for %FEV1 compared with term-born controls were -7.2% (-8.7% to -5.6%), -16.2% (-19.9% to -12.4%) and -18.9% (-21.1% to -16.7%), respectively. Pooling all data on preterm-born subjects whether or not there was a control group gave a pooled %FEV1 estimate of 91.0% (88.8% to 93.1%) for the preterm-born cohort without BPD, 83.7% (80.2% to 87.2%) for BPD28 and 79.1% (76.9% to 81.3%) for BPD36. Interestingly, %FEV1 for BPD28 has improved over the years. CONCLUSIONS: %FEV1 is decreased in preterm-born survivors, even those who do not develop BPD. %FEV1 of survivors of BPD28 has improved over recent years. Long-term respiratory follow-up of preterm-born survivors is required as they may be at risk of developing chronic obstructive pulmonary disease.
