Hemoglobin levels were determined for 4,081 children, ages 2 1/2-14 years, from a biracial southern community. Back children had lower levels of hemoglobin than white children at every age interval with a mean difference of 0.64 gm/dl. This diffence persisted even when comparing children from similar socioeconomic level households. If black children maintain lower hemoglobin levels consistent with optimum health than do white children, then different hemoglobin standards may be warranted for each race.
对来自一个南方混血社区的4081名年龄在2岁半至14岁之间的儿童进行了血红蛋白水平测定。在每个年龄区间，黑人儿童的血红蛋白水平均低于白人儿童，平均差异为0.64克/分升。即使在比较来自社会经济水平相似家庭的儿童时，这种差异仍然存在。如果黑人儿童保持比白人儿童更低但符合最佳健康状态的血红蛋白水平，那么每个种族可能需要不同的血红蛋白标准。
