In this investigation, 70 children from American Samoa participated in a standardized assessment of blood pressure and heart rate reactivity during a television video game. Data from Samoan children were compared with previously collected data from children (both black and white) residing in the continental United States. Samoan and black children demonstrated similar blood pressure reactivity (both absolute and delta values; P > .05); Samoans and blacks demonstrated greater blood pressure reactivity than whites (P < .05). Ethnic differences in heart rate reactivity were not as pronounced. After we adjusted reactivity values for ethnic differences in age, Quetelet index, and resting measurements, Samoans' reactivity continued to be more similar to the reactivity of blacks than that of whites. Results provide further evidence of ethnic differences in children's pressor reactivity; these differences may be related to differences in hypertension in adulthood.
在这项调查中，70名美属萨摩亚儿童参与了一项在电视电子游戏期间对血压和心率反应性的标准化评估。将萨摩亚儿童的数据与之前收集的居住在美国大陆的儿童（包括黑人和白人）的数据进行了比较。萨摩亚儿童和黑人儿童表现出相似的血压反应性（绝对和差值；P>.05）；萨摩亚人和黑人的血压反应性高于白人（P<.05）。心率反应性的种族差异不那么明显。在我们针对年龄、奎特利指数和静息测量值中的种族差异调整反应性值后，萨摩亚人的反应性与黑人的反应性相比，仍比与白人的反应性更相似。结果进一步证明了儿童升压反应性存在种族差异；这些差异可能与成年期高血压的差异有关。
