Background: Constitutional advancement of growth (CAG) is the growth pattern of early growth acceleration that has been shown to be characteristic in girls with idiopathic precocious puberty (IPP). The aim of this study was to examine the growth pattern of girls with early puberty compared to girls with IPP.
Methods: We studied the growth pattern, from birth to presentation, of 61 girls with early puberty, of 40 girls with IPP and of 100 healthy girls with normal pubertal onset that served as controls.
