Secondary sexual development in rural and urban South African black children.
Ann Hum Biol. 1993 Nov-Dec; 20(6):583-93.AH

Abstract

The timing and duration of secondary sexual development in two samples of rural and urban South African black children were investigated using the Tanner staging techniques and compared to similar data from Switzerland and England. In general rural black children were consistently delayed in the age at which they entered the events of puberty, and took longer to pass through each of the stages. Urban black children, from good socioeconomic backgrounds, were advanced in relation to their rural peers and slightly ahead of the European samples. There were no significant differences in the sequence of events. Estimates of testicular volume on the well-off urban boys demonstrated that they exhibited similar volumes to European boys at similar ages. It is suggested that the British clinical longitudinal growth standards could be effectively used to sensitively monitor the growth and maturation of black urban children from good socioeconomic backgrounds.
