Marshall ZA, Mackintosh KA, Lewis MJ, et al. - Researchers conducted this cross-sectional study for analyzing the role of physical activity accumulation in cardiovascular disease risk for children with type 1 diabetes. Pulse wave velocity (PWV), augmentation index and heart rate variability have been evaluated cross‐sectionally in children with (n = 29, 12.1 ± 2.1 years) and without (n = 19, 12.1 ± 2.1 years) type 1 diabetes. According to results, diabetic children showed a higher PWV and a greater volume of light physical activity, a more negative intensity gradient, a lower average acceleration and less time in bouted moderate‐to‐vigorous physical activity (MVPA). Overall, MVPA was found to be the most closely linked to central stiffness, stressing the importance of adhering to activity guidelines. Diabetic children had worse cardiovascular health than their counterparts, which was possibly due to lower intensity and volume of physical activity, suggesting that physical activity intensity could be a primary priority for potential interventions.
