Body Proportions in Precocious Puberty

Abstract
Sitting height (SH) and sub-ischial leg length (SLL) were measured in 10 boys and 16 girls with precocious puberty; the patients were aged 1.5-13.4 yr at the time. Standard deviation scores (SDS) calculated for chronological age and bone age showed higher scores for SH than for SLL in all but 2 patients, both girls: the differences between the SDS for SH and SLL were more marked in the boys. Growth of the trunk is usually greater than growth of the legs in precocious puberty, particularly in boys.
