School‐age children enjoyed good respiratory health and fewer allergies despite having lung disease after preterm birth
2016
AIM: This study explored the under-researched area of whether preterm birth or bronchopulmonary dysplasia (BPD) affected hospitalisation rates, allergies or health-related quality of life (HRQoL). METHODS: We studied 88 schoolchildren born preterm at a mean gestational age of 28.8 weeks (range 24.1-31.9) and matched term-born controls at the mean age of 11 years (range 8-14). Hospitalisations after the first discharge were recorded, skin prick allergy tests were performed and HRQoL was assessed with a parental questionnaire. RESULTS: Preterm children were hospitalised more than controls (64% versus 39%, p = 0.001), mostly before two years of age. The adjusted odds ratios (OR) for two-year-old preterm-born children being hospitalised for wheezing was 8.2 (95% CI 2.0-34.1). BPD affected 56% of the preterm children, but did not influence hospitalisations, and the positive skin prick rate was similar between the preterm and term-born children (35% versus 48%, p = 0.126). Preterm BPD children had fewer positive skin prick tests than those without BPD. HRQoL was lower in preterm than term children (81.25 ± 10.84 versus 86.80 ± 9.60, p = 0.001). CONCLUSION: Most health problems experienced by preterm-born schoolchildren occurred before two years of age and were mainly wheezing disorders. BPD decreased atopy but had no influence on hospitalisation rates.
