Key result
Cardiovascular reactivity to psychological stress was associated with future resting blood pressure, with Black children demonstrating greater reactivity than White children over a 1-year period.
Why the study?
Does cardiovascular reactivity to psychological stress predict subsequent resting blood pressure in children?
Population
477 children enrolled in 3rd grade (434 followed up in 4th grade), including Black and White children.
Comparison
Cardiovascular reactivity testing via a video… vs Resting measurements; comparison between Black…

Greater reactivity in Black children is hypothesis-generating; leaves open links to later hypertension without prospective validation.

Does cardiovascular reactivity to psychological stress predict subsequent resting blood pressure in children?
Cardiovascular reactivity to psychological stress in childhood predicts subsequent resting blood pressure and exhibits racial differences that may relate to future hypertension risk.
Murphy et al. (1991) conducted a cohort in Cardiovascular reactivity and blood pressure (n=477). Cardiovascular reactivity to psychological stress and race vs. White children (for race comparison) was evaluated on Blood pressure and heart rate at rest and during a video game procedure. Cardiovascular reactivity to psychological stress was associated with future resting blood pressure, with Black children demonstrating greater reactivity than White children over a 1-year period.
