The purpose of this study was to determine if there are racial differences in the blood pressure patterns among urban adolescents. Blood pressure (BP) was measured according to Task Force guidelines in health-screening and education sessions conducted in urban public and parochial high schools. The prevalence of BP > or = 95th% (HBP) on initial screening was determined in a population of 3,349 students. Differences in prevalence of HBP among race, sex, and age groups were tested for significance by chi 2 analysis. The overall prevalence of HBP in this urban adolescent population was 8.1%. Significant race differences were present in females (blacks = 6.6% versus non-Hispanics = 2.9%, p < 0.01). Within the black females, HBP occurred more frequently among the girls attending predominantly black public schools (7.7%) compared to an interracial parochial school (2.0%) p < 0.001. This difference could not be explained by weight, height, or the occurrence of obesity. The observed BP differences within black females, by school, may reflect a family-environment effect on cardiovascular risk.
本研究的目的是确定城市青少年的血压模式是否存在种族差异。在城市公立和教会高中开展的健康筛查与教育活动中，根据特别工作组指南测量血压。在3349名学生群体中确定了初次筛查时血压≥第95百分位数（高血压）的患病率。通过卡方分析检验种族、性别和年龄组之间高血压患病率的差异是否具有显著性。该城市青少年人群中高血压的总体患病率为8.1%。女性中存在显著的种族差异（黑人=6.6%，非西班牙裔=2.9%，p<0.01）。在黑人女性中，主要就读于黑人公立学校的女孩中高血压的发生率（7.7%）高于就读于跨种族教会学校的女孩（2.0%），p<0.001。这种差异无法用体重、身高或肥胖的发生情况来解释。观察到的黑人女性中按学校划分的血压差异可能反映了家庭环境对心血管风险的影响。
