Abstract

The ambulatory arterial stiffness index (AASI) and the symmetric ambulatory arterial stiffness index (s-AASI) have been shown to correlate to arterial stiffness in adults. This study assesses these indices with anthropometric and blood pressure (BP) measures in children. A total of 102 children at a pediatric hypertension clinic who had ambulatory blood pressure monitoring (ABPM) done from 2009 to 2013 were included (75% males, 7-22yo, 47% hypertensive, 24% prehypertensive, and 34% white-coat hypertensives). AASI is 1 minus the regression slope of diastolic BP values on systolic BP values from a 24-hour ambulatory blood pressure monitoring. s-AASI is the symmetric regression of AASI. Obese patients had a significantly higher AASI. s-AASI correlated with systolic BP variability. In multivariable regression, BP variability independently correlated with AASI and s-AASI. s-AASI is related to systolic dipping.AASI and s-AASI are highly dependent on BP variability in children. Further studies are necessary to assess their utility.
