Early indicators of cardiovascular disease are evident in children and adolescents with cerebral palsy.

Abstract Background Cardiovascular disease (CVD) is a leading cause of early mortality among young adults with cerebral palsy. While low physical activity in childhood has been hypothesized as a potential contributor to increased CVD risk in early adulthood, little is known about timing of vascular disease progression and the presence of subclinical atherosclerosis has not been extensively evaluated in children with cerebral palsy. Objective The aim of this study was to determine if measures of vascular structure and function used are different between children and adolescents with and without cerebral palsy. Methods In this cross-sectional study, we measured carotid intima-media thickness (CIMT), and brachial artery flow-mediated dilation (FMD) of children with and without cerebral palsy. Group means for CIMT and brachial artery FMD absolute (FMDA) and percent of relative change (FMDR%) were compared using Wilcoxon rank-sum tests. Results A total of 26 children and adolescents with cerebral palsy (46.1% girls, mean age=15.0±2.0 years) and 19 controls (68.4% girls, mean age=13.3±2.6 years) participated. Children with cerebral palsy had significantly greater average CIMT (0.43±0.02mm) than children without cerebral palsy (0.41±0.01mm, p=0.04), and lower FMDA (0.16±0.15mm vs. 0.29±0.20mm; respectively, p=0.03). Conclusions Children and adolescents with cerebral palsy may exhibit impairments in vascular structure and function which represent an increased risk of premature atherosclerosis compared to children without cerebral palsy. Additional research to identify risk factors specific to children with cerebral palsy that would support the development of effective screening processes for early identification would enable clinicians to implement targeted preventive strategies.
