A 2-year longitudinal survey of height and weight was conducted on 2,058 Johannesburg children aged 3.5 - 18.5 years. The principal findings were that both height and weight increased more rapidly in white than in black children, and that attained height and weight were significantly greater in whites. The ponderal index (a measure of weight-for-height) was greatest in black females and lowest in black males. Comparison with a survey carried out 12 years previously suggests that there has been an increase in the mean weight of the black population over this period.
对约翰内斯堡2058名年龄在3.5至18.5岁的儿童进行了为期两年的身高和体重纵向调查。主要研究结果是，白人儿童的身高和体重增长速度均快于黑人儿童，且白人儿童的最终身高和体重明显更高。肥胖指数（身高体重比的一种衡量指标）在黑人女性中最高，在黑人男性中最低。与12年前进行的一项调查相比，这表明在此期间黑人人口的平均体重有所增加。
