Gradient b (SE) derived from log–log relationships between height and SKF in children who reported being in Tanner stages 1–3 (T1–3) and in Tanner stages 4–5 (T4–5) for breast development in girls and genital development in boys, using line drawings (Taylor et al., 2001)19 based on Tanner (1962)48 (mean ± SD).

Notes: a Data presented as mean ± SD (95%CI); b Sum of triceps, subscapular, biceps, and suprailiac SKF; c Trunk-to-extremity SKF ratio ((subscapular+suprailiac)/(triceps+biceps)); Bonferroni-corrected α = 0.01.
* p ≤ 0.01, ** p ≤ 0.005, *** p ≤ 0.001, significant relationship between height and SKF; #p = 0.016, compared with girls in T1–3 (independent t test).
Abbreviations: CI = confidence interval; SKF = skinfold thickness; T/E SKF = the ratio of trunk-to-extremity skinfold thicknesses SKF.
