Vascular Health and Risk Factors in Children With Down Syndrome
In Brief
An observational study evaluating Evaluate vascular disease risk factors in children with Down Syndrome and Determine the associations between cardiovascular disease risk factors and markers of early atherosclerosis in children with Down Syndrome for Down Syndrome and 2 related conditions. Completed, enrolled 55 participants across 1 site.
Detailed Summary
This is a prospective, multicenter, cross-sectional study to evaluate prevalence of vascular risk factors in children with Down Syndrome and to determine the association between vascular disease risk factors and objective markers of early atherosclerosis.
Study Details
Timeline
Interventions
We will determine CV disease risk profiles in children with DS at our centers. We will compare these data to published national norms of children without DS. Risk factor data will include: anthropometric measures; blood pressure; history of congenital heart disease and associated surgery, sleep apnea, hypothyroidism, and cancer; fasting blood draw \[lipid panel with subfractions (NMR), insulin, glucose, and CRP\].
We will perform PWV, CIMT, and CD studies in children with DS and compare these data to available data in children without DS. We will also perform multivariable analysis of the influence of combinations of CV disease risk factors on markers of early atherosclerosis in children with DS. Hypothesis: CV disease risk factors will correlate with markers of early atherosclerosis in children with DS but the associations between risk factors and markers of early atherosclerosis will differ between children with DS vs. the general population of children.
