据作者所知，尚未发表关于儿童血压种族差异与体型差异的大型全国性研究。该报告详细介绍了美国黑人儿童和白人儿童收缩压和舒张压的异同，并研究了年龄、性别和体型对血压水平种族差异的影响。使用 1978 年至 1991 年间发表的八项大型流行病学研究中的坐位收缩压和舒张压标准化测量结果，其中包括 47,196 名儿童 68,556 次测量收缩压和 38,184 名儿童 52,053 次舒张压测量； 51%（24,048 名儿童）是男孩，37%（17,466 名儿童）是黑人。总体而言，儿童期和青春期的收缩压或舒张压似乎没有什么实质性的种族差异。观察到的差异很小且不一致，并且通常用体型差异来解释。种族群体与体重指数 (BMI) 之间存在相互作用，导致这些发现：在 BMI 水平较低的情况下，黑人比白人有更高的血压和高血压，但在 BMI 水平最高时，白人比黑人有更多的高血压（收缩压或舒张压）。
No large national studies of ethnic differences in blood pressure among children accounting for body size differences have been published, to the authors' knowledge. This report details the similarities and differences in systolic and diastolic blood pressures between Black children and White children in the United States and examines the effects of age, sex, and body size on ethnic differences in blood pressure levels. Standardized measurements of seated systolic and diastolic pressures from eight large epidemiologic studies published between 1978 and 1991 that included measurements of 47,196 children on 68,556 occasions for systolic pressure and for 38,184 children on 52,053 occasions for diastolic pressure were used; 51 percent (24,048 children) were boys and 37 percent (17,466 children) were Black. Overall, there appear to be few substantive ethnic differences in either systolic or diastolic pressure during childhood and adolescence. The differences that were observed were small, inconsistent, and often explained by differences in body size. There was an ethnic group-body mass index (BMI) interaction that resulted in these findings that at lower levels of BMI Blacks have higher blood pressure and more hypertension than do Whites, but that at the highest levels of BMI, Whites have more hypertension (systolic or diastolic pressure) than do Blacks.
