In this prospective investigation, all children enrolled in the public third-grade classrooms of an entire county (n = 474) had blood pressure measured both at rest and during a stressful television video game. Examinations were repeated in 4 subsequent years when cohort children as well as newly enrolled children were in grades 4, 5, 7, and 8. Both cross-sectional and longitudinal analyses indicated that black children demonstrated significantly greater systolic and diastolic pressor reactivity than white children. These data suggest that ethnic differences in children's pressor reactivity presage ethnic differences in adulthood hypertension.
在这项前瞻性调查中，一个县所有公立三年级教室的所有儿童（n = 474）在休息时和玩紧张的电视电子游戏期间都测量了血压。在随后的4年里，当队列中的儿童以及新入学的儿童分别处于4、5、7和8年级时，重复进行了检查。横断面和纵向分析均表明，黑人儿童的收缩压和舒张压升压反应性明显高于白人儿童。这些数据表明，儿童升压反应性的种族差异预示着成年期高血压的种族差异。
