Abstract
Aims: To know if nutrition status (as measured by BMI) is associated to lung function of infants born preterm (PT) with or without bronchopulmonary dysplasia (BPD)
Methods: By means of the raised volume rapid thoracoabdominal compression (RVRTC) technique, FVC, FEV0.5, FEF50, FEF75, and FEF25-75 were measured in 61 PT without BPD (65.6% male; corrected age 7.2±0.7 mo.) and in 55 PT with BPD (59.8% male; corrected age 7.75±0.9 mo.). A multiple regression analysis -stratified for BPD- was performed for BMI z-score (as calculated according to WHO values) and each lung function parameter (dependent variable), controlling for gender, gestational age, current corrected age, height, birth weight, smoking exposure in pregnancy.
Results: The coefficients of the regression analyses and their significance are shown in table.
Conclusions: Lung function of infants 7-8 months of age, born PT without BPD, increases with BMI. This does not seem to be the case in infants of similar age born PT but with BPD.
