Reference curves for biceps, triceps, subscapular and suprailiac skinfolds in Dutch children from 7-14 years.

Box-Cox transformation of skinfold measurement data from the Nymegen Growth Study produced reference curves for biceps, triceps, subscapular and suprailiac skinfolds and their sums with an acceptable Gaussian distribution at all ages. The population sample, resulting in 1850 skinfold measurements for boys and 2250 for girls by a single observer, was obtained by random selection and can be considered as representative for The Netherlands. The Gaussian distribution after Box-Cox transformation allows the use of standard deviation scores. Seven percentile curves are presented for boys and girls of 7-14 years of age.
