Data on haemoglobin concentration, red cell count, packed cell volume, mean cell volume, mean cell haemoglobin and mean cell haemoglobin concentration for 'normal' children aged 1-4 years living on the Highveld (altitude 1400-1800 m) are presented in yearly age groups. The children were defined as normal on the basis of having growth attainment and iron, folate and vitamin B12 nutrition within accepted normal limits. The results obtained differ from the standard reference values published for children resident at sea level. It is suggested that the mean (+/- 2 SD) ranges presented be used as normal ranges in the population studied.
给出了居住在高原地区（海拔1400 - 1800米）的1 - 4岁“正常”儿童的血红蛋白浓度、红细胞计数、血细胞比容、平均红细胞体积、平均红细胞血红蛋白含量和平均红细胞血红蛋白浓度的数据，按年龄分组列出。这些儿童基于生长发育以及铁、叶酸和维生素B12营养在公认的正常范围内而被定义为正常。所获得的结果与针对居住在海平面的儿童所公布的标准参考值不同。建议将给出的均值（±2标准差）范围用作所研究人群的正常范围。
