Aim To assess the lung functions with impulse oscillometry (IOS) and spirometry in children with type 1 diabetes mellitus (T1DM). Methods Fifty‐one children with T1DM, and sex‐ and age‐matched 53 healthy control (HC) subjects were included in this study. Demographic, clinical, and laboratory characteristics of the subjects were recorded and their pulmonary functions were analyzed by IOS and spirometry. Results In IOS, zR5, zR10, and zR20 levels were higher in children with T1DM compared with HCs ( P = .019, P = .017, and P = .002, respectively). In spirometry, zFEF75 and zFEF25‐75 were lower in children with T1DM compared with HCs ( P = .025, P = .001, respectively). In IOS, zR5‐20 ( P = .008, P = .005, respectively) and zAX ( P = .013, P = .009, respectively) were significantly lower in good‐controlled group compared with moderate‐ and poor‐controlled group. In spirometry, zFEF25‐75 was significantly higher in good‐controlled group compared with moderate‐ and poor‐controlled group ( P = .005, P = .009, respectively). HbA1c was positively correlated with zR5‐20 value ( r = .339; P = .017) in male children with T1DM. The duration of the disease was positively correlated with zR5‐20 ( r = .290; P = .043) and zFres ( r = .358; P = .010). According to the receiver operating characteristic curve analysis to estimate optimal cut‐offs to discriminate good control level of T1DM (HbA1c < 7%), a zR5‐20 ≤ 2.28 demonstrated a 75.0% sensitivity and 82.9% specificity, with an area under the curve of 0.805 ([confidence interval, 0.615‐0.995]; P = .007). Conclusions This study showed subclinical impairment of lung functions which is associated with disease duration and the degree of metabolic control in children with T1DM.
