Background There is a paucity of data on lung physiology in late‐preterm children, who may be exposed to a risk of decline in lung function during childhood. In this study, we evaluated lung function in preschool children born late preterm using impulse oscillometry (IOS), and compared the results with those obtained in healthy term‐born children. Methods Children between 3 and 7 years of age who were born late preterm and who were being followed up at the outpatient clinic were included as the late‐preterm group. Age‐matched healthy term‐born children served as controls. A total of 90 late‐preterm and 75 healthy children were included in the study. At 5–20 Hz, resistance (R5–R20), reactance (X5–X20), impedans (Z5) and resonant frequency were measured on IOS. Results Mean IOS R5 and R10 were significantly higher in the late‐preterm group than in the control group (P
