Abstract
Publisher Summary This chapter discusses growth charts and pubertal staging. Until about age nine, the cross-sectional and longitudinal standards for height and weight are essentially the same; but when puberty starts, the two sorts of standards part company. The reason for this is the variation in tempo of growth among children, coupled with the change in growth velocity that occurs at puberty. The chapter discusses the conventional rating scales used for giving semiquantitative assessments of the development of breasts, male genitalia, and pubic hair. Scales that confound genitalia and pubic hair in boys or breasts and pubic hair in girls are not recommended for use by endocrinologists, who have to deal with extreme normal variants and actual abnormalities of pubertal sequence. The information obtained from staging may be plotted in the height-attained charts or on separate, larger charts. Frequently, plotting against bone age is more important than plotting against chronological age.
