Aspects of the anthropometric growth and development of Johannesburg children in two racial groups

Abstract :

Aspects of the growth and development of 2058 Black and White children aged from 3,5 to 18,5 years are investigated using data obtained from a two-year, mixed longitudinal survey conducted during 1976/1977 and 1977/1978 in Johannesburg and Soweto. Features studied are sexual maturity, attained levels and increments of height, weight, triceps fat and subscapular fat as well as the factors influencing attained size. The White children, whose growth resembles that of British children, are physically larger and faster growing than the Black children. Furthermore, although the age of pubertal initiation is similar in the two races, the Whites complete sexual maturity within a shorter time period than do the Black children. Features of the growth of the Black children are their greater fat increment and the short stature and obesity of the females at the end of the growth period. Factors which adversely influence attained size, especially of White children, are a disadvantaged socio-economic environment and competitive conditions such as overcrowding, large sibling-numbers and a senior position in the family. It is mainly in the White children, though, that the characteristic of sexual dimorphism is displayed.
