Key result
Aggressive children exhibited higher baseline heart rates and lower heart rate reactivity, with the greatest cardiovascular response in those with a parental history of hypertension.

Does aggression affect cardiovascular response in children?
Aggression in children is associated with altered cardiovascular responses, particularly in those with a family history of hypertension, highlighting behavioral factors in early cardiovascular risk.
May flag early CV risk in aggressive children with hypertensive parents; hypothesis-generating and should not yet change practice.
OBJECTIVE: To examine cardiovascular response as a function of children's aggression after controlling for the effects of known risk factors. METHOD: Participants were 140 children in second, fourth, and sixth grades. Teachers completed the Matthews Youth Test for Health, a measure that includes questions pertaining to children's aggression. Measures of blood pressure and heart rate were obtained during baseline, academic quiz, and recovery. RESULTS: Increasing age and body mass index were associated with increased cardiovascular responses. Aggressive children exhibited higher heart rates at baseline and lower heart rate reactivity. Aggressive children with a positive parent history of hypertension exhibited the greatest cardiovascular response. CONCLUSIONS: These results provide further support for the identification of behavioral factors that increase cardiovascular risk in children.

Kerri Schneider (2002) conducted a cross-sectional in Cardiovascular risk (n=140). Aggression vs. Lower aggression was evaluated on Cardiovascular response (blood pressure and heart rate). Aggressive children exhibited higher baseline heart rates and lower heart rate reactivity, with the greatest cardiovascular response in those with a parental history of hypertension.
