Cross-sectional estimate of percent annual growth rate of limb segments and head-trunk height by age.

<p>Growth rates calculated from LMS model median values for 3 months either side of age stated for female participants. ‘% annual growth rate’ refers to the estimated percentage increase in raw measurements over a year based on the median measurement at the start of the 6 month period over which the rate is calculated. Male data demonstrate the same pattern (not shown). Measurements are lengths, apart from ‘head circ.’ which is head circumference.
