Task: Intent Identification
Input (English): This study evaluated the prospective relationship between cardiovascular reactivity to psychological stress and increases in resting blood pressure across a 3-year period among a multiethnic pediatric sample (N = 149).', 'Systolic and diastolic blood pressure; EKG heart rate, pre-ejection period, and mean successive difference of R to R intervals; and impedance-derived measures of cardiac output, stroke volume, and total peripheral resistance were collected during performance of four tasks that elicited different hemodynamic response patterns. Changes from baseline to each task were standardized and averaged to form eight composite scores. Analyses adjusted for time 1 baseline blood pressure and age, body mass index at baseline and change to follow-up, and duration of follow-up.', 'Rises in SBP over the follow-up period were independently predicted by SBP (beta = 0.161, p =.009), DBP (beta = 0.132, p =.02), and CO (beta = 0.144, p =.02) composite measures of reactivity. Rises in DBP over the follow-up period were predicted by DBP (beta = 0.292, p =.003, respectively), and MSD (beta = -0.176, p <.03) composite measures of reactivity. TPR reactivity was not related prospectively to blood pressure rises.
