RT Journal Article SR Electronic T1 Prepubertal height velocity references over a wide age range. JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 1277 OP 1280 DO 10.1136/adc.67.10.1277 VO 67 IS 10 A1 B Rikken A1 J M Wit YR 1992 UL http://adc.bmj.com/content/67/10/1277.abstract AB In order to correct height velocities for the confounders age and sex, SD scores can be calculated using the mean and the SD of the height velocity in the normal population. However, current methods are inappropriate for prepubertal children in the age range in which puberty occurs, because reference groups then consist of a mixed prepubertal/pubertal population. The mathematical infancy-childhood-puberty (ICP) model opens up the possibility of dissecting the puberty component from the total growth curve. New references for height velocity for prepubertal children calculated over a 12 month interval up to the ages of 15.5 years (boys) and 13.5 years (girls) have been constructed on the basis of adaptations of the ICP model and the Swedish longitudinal growth study.
