Data on respiratory morbidity was collected in Spanish children born PT (30-35+6 weeks) and in those born T at 4 and 6 years. Spirometry was measured in each visit.Results: We followed up 105 children (55 T/50 PT). Both groups had a similar bronchiolitis incidence (T 40%, PT 45%). Hospitalization for respiratory infections at 4 and 6 years and physician diagnosed wheezing at 4 years were significantly higher in PT (Table 1). No significant differences were found in z-score FVC, FEV1 or FEF25-75 neither at 4 nor 6 years between both groups.Conclusions: Children born moderate and late PT have more respiratory morbidity, reflected on number of admissions for respiratory infections and wheezing episodes, compared to T, even though no differences in LF were found between them.
