Aim: To estimate and compare pubertal growth timing and intensity in height, Tanner stage
markers and testis volume. Subjects and methods: Data on height, genital stage, breast …

Secular trends towards earlier puberty, possibly caused by new environmental triggers,
provide a basis for periodic evaluation of the influence and interaction of genetic and …

Background: Growth and pubertal development have each been studied in detail, but rarely
in conjunction. Aim: The study aim was to determine what somatic and pubertal …

Background: The SITAR model expresses individual pubertal height growth in terms of
mean size, peak height velocity (PHV) and age at PHV. Aim: To use SITAR to identify the …

This paper analyzed the intensity and duration of height growth during puberty in boys and
girls in relation to rhythm of maturation. A longitudinal clinical follow‐up between ages of 10 …

Background: This is a methodical investigation into the problem of estimating parameters for
the pubertal spurt (PS). The variability involved in determining the timing, intensity and …

PURPOSE:(1) To propose a new method using statistical modeling to determine relative
timing of pubertal maturation;(2) to validate the new method by evaluating its relationship …

Evaluation of Tanner stage and especially assessment of testicular volume should both be
used in epidemiological studies. We speculate that the association between fat mass and …

Whether children, especially girls, are entering and progressing through puberty earlier
today than in the mid-1900s has been debated. Secular trend analysis, based on available …

Amulticategory item-response theory model was developed to characterize developmental
changes in three items relating to the assessment of puberty in adolescent twin girls and …
