Height-for-age, weight-for-age, weight-for-height, and height gain were studied in two-thousand normal urban black Southern African schoolchildren from Umtata, Republic of Transkei, Southern Africa. The height-for-age data in the present study were less than those of the USA National Centre for Health Statistics (NCHS) data and the overall distribution of height for age was between the 3rd and 75th percentiles of NCHS. In boys, after the age of 13 years, the weight-for-age data in the present study were statistically less than NCHS and the overall distribution of weight-for-age data was between the 10th and 75th percentiles of NCHS. The weight for height in the present study was slightly greater than NCHS and the overall distribution of weight for height data was between 25th and 90th percentiles of NCHS. Adolescent growth spurt occurred in girls at the age of around 11 years, while in boys it occurred around 12 years. The mean duration of the pubertal period was 2 years for boys and girls. Peak height velocity (PHV) was 7.7 and 7.9 cm/year in boys and girls, respectively. The present study may be used a source of reference for urban black schoolchildren in Africa.
对来自南非特兰斯凯共和国乌姆塔塔的2000名正常城市黑人南非学童的年龄别身高、年龄别体重、身高别体重和身高增长情况进行了研究。本研究中的年龄别身高数据低于美国国家卫生统计中心（NCHS）的数据，年龄别身高的总体分布在NCHS的第3百分位数和第75百分位数之间。在男孩中，13岁以后，本研究中的年龄别体重数据在统计学上低于NCHS，年龄别体重数据的总体分布在NCHS的第10百分位数和第75百分位数之间。本研究中的身高别体重略高于NCHS，身高别体重数据的总体分布在NCHS的第25百分位数和第90百分位数之间。女孩的青春期生长突增发生在11岁左右，而男孩则发生在12岁左右。男孩和女孩青春期的平均持续时间均为2年。男孩和女孩的身高生长高峰速度（PHV）分别为7.7厘米/年和7.9厘米/年。本研究可作为非洲城市黑人学童的参考资料来源。
