Hemoglobin and mean corpuscular volume values appear to be lower among black than among white children. Blood hemoglobin concentration and red cell mean corpuscular volume were measured in 4,074 black boys and girls aged 1 through 20 years who lived near sea level. This is the largest hematologic survey of healthy American black children and adolescents to date. Children with sickle cell disease and elevated hemoglobin F were excluded from the study, but children with the traits for hemoglobin S, hemoglobin C, thalassemia, and iron deficiency were not. The 3rd and 97th percentile values reported here are close to the 95 percent confidence limits, and are adjusted for age and sex.
黑人儿童的血红蛋白和平均红细胞体积值似乎低于白人儿童。对生活在海平面附近、年龄在1至20岁的4074名黑人男孩和女孩进行了血血红蛋白浓度和红细胞平均红细胞体积测量。这是迄今为止对美国健康黑人儿童和青少年进行的规模最大的血液学调查。患有镰状细胞病和血红蛋白F升高的儿童被排除在研究之外,但具有血红蛋白S、血红蛋白C、地中海贫血和缺铁特征的儿童未被排除。这里报告的第3和第97百分位数接近95%置信限,并根据年龄和性别进行了调整。
