Stability of children's and adolescents' hemodynamic responses to psychological challenge: A three‐year longitudinal study of a multiethnic cohort of boys and girls
Key result
Hemodynamic responses to psychological challenge demonstrated moderate temporal stability across 3 years in a pediatric cohort (rs = 0.36 to 0.51).
Why the study?
Are hemodynamic responses to psychological challenge stable over a 3-year period in children and adolescents?
Population
149 multi-ethnic children and adolescents

Implication
Suggests hemodynamic reactivity may be a stable trait in children; leaves open its role in long-term cardiovascular risk assessment.
Study Design
Type
Cohort (n=149)
Structured PICO
Are hemodynamic responses to psychological challenge stable over a 3-year period in children and adolescents?
P
Population
149 children (8-10 years) and adolescents (15-17 years) followed for an average of 3 years to assess the stability of hemodynamic responses to stress.
E
Exposure
Psychological challenge (three tasks)
O
Outcome
Temporal stability of hemodynamic responses (stroke volume, cardiac output, total peripheral resistance, and pre-ejection period) measured by impedance cardiographysurrogate
Main Result
Effect estimate: rs = 0.36 to 0.51
Hemodynamic responses to psychological stress in children and adolescents show moderate temporal stability over 3 years, though the magnitude of responses changes with aging.
Cite This Study
Matthews et al. (2002) reported a cohort. Psychological challenge vs. Baseline was evaluated on Temporal stability of composite task-induced changes in stroke volume, cardiac output, total peripheral resistance, and pre-ejection period (rs = 0.36 to 0.51). Hemodynamic responses to psychological challenge demonstrated moderate temporal stability across 3 years in a pediatric cohort (rs = 0.36 to 0.51).
