Assessment of arterial stiffness in paediatric patients with type 1 diabetes mellitus.

To investigate early indicators of cardiovascular disease (CVD) in children and adolescents with type 1 diabetes mellitus (T1DM), focusing on pulse wave velocity (PWV) and its associations with various anthropometric and glycemic parameters. A total of 124 children and adolescents with T1D (mean age 10.75 ± 3.57 years) were included in this cross-sectional study. Anthropometric data, including height, weight, body mass index (BMI), glycemic parameters, such as HbA1c and time in range (TIR) were assessed. PWV was assessed by oscillometric method using the Mobil-O-Graph PWA device. Univariate and multivariate linear regression were used to explore the association of PWV z-score with anthropometric, demographic, and glycaemic variables. Significant negative association between PWV and age and height (β = -0.336, 95 % CI -0.44 to -0.25, p < 0.001 and β = -0.491, 95 % CI -0.62 to -0.36, p < 0.001, respectively), while gender showed a significant positive association with PWV, with females displaying higher PWV values compared to males (β = 0.366, 95 % CI 0.17 to 0.56, p < 0.001). TIR was positively associated with PWV (β = 0.092, 95 % CI 0.01 to 0.16, p = 0.017 only for patients having TIR ≤ 50 %. Finally, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were positively associated with PWV (β = 0.086, 95 % CI 0.02 to 0.14, p = 0.007 and β = 0.152, 95 % CI 0.07 to 0.23, p < 0.001, respectively). Youth with T1DM who spend <50 % of time in range exhibit uniquely increased signs of arterial stiffness, indicating that poor glycemic control may contribute to early vascular damage. Differences related to age, gender and height should be considered.
