Stature and its components in healthy children, sexual dimorphism and age related changes.

This paper reports a cross sectional study of three components of stature (suprapelvic height, pelvic height and subischial height) for a sample of 585 healthy children aged 8-15 years. Data are also given for stature, sitting height and bi-iliac width. Sexual dimorphism is revealed in both suprapelvic height and pelvic height. In girls, the increase in pelvic height is detected before the increase in bi-iliac width and before the appearance of secondary sexual characteristics. The data provide the first 'standards' for each of suprapelvic height and pelvic height for clinical use.
