In 307 Native American (NA), 1784 black (B), and 7777 white (W) children in grades 1, 2, and 3 in Minneapolis schools (99% overall response rate), blood pressure (BP) was measured supine in the right arm after 5 minutes' rest by trained technicians using a random zero BP device. In addition, height, weight, pulse rate, and triceps skinfold thickness were measured. Among children aged 6 through 9 years, NA children had slightly higher systolic BP (SBP) than B or W children overall (mean SBP: NA 106, B 104, W 105 mm Hg) and for nearly all age sex groups. In contrast, Phase 4 and 5 diastolic BP (DBP) were consistently lower in NA children ( mean DBP4: NA 64, B 69, W 67 mm Hg); NA children also had lower pulse rates, greater pulse pressures, similar or slightly lower mean BP, similar height, greater weight, body mass index, and triceps skinfold. Multiple regression analyses revealed that the slightly higher SBP in NA children was explained almost entirely by greater ponderosity. However, the lower DBP could not be explained statistically by any of the variables measured.
在明尼阿波利斯市学校1、2、3年级的307名美国原住民（NA）、1784名黑人（B）和7777名白人（W）儿童中（总体回复率为99%），经过培训的技术人员使用随机零点血压计，让儿童在休息5分钟后仰卧测量右臂血压。此外，还测量了身高、体重、脉搏率和肱三头肌皮褶厚度。在6至9岁的儿童中，NA儿童的收缩压（SBP）总体上略高于B或W儿童（平均SBP：NA为106，B为104，W为105毫米汞柱），且几乎在所有年龄性别组中都是如此。相比之下，NA儿童的4期和5期舒张压（DBP）始终较低（平均DBP4：NA为64，B为69，W为67毫米汞柱）；NA儿童的脉搏率也较低，脉压较大，平均血压相似或略低，身高相似，体重、体重指数和肱三头肌皮褶厚度更大。多元回归分析显示，NA儿童略高的SBP几乎完全由更高的肥胖程度所解释。然而，较低的DBP无法用所测量的任何变量进行统计学解释。
