Of 27 boys and 16 girls with untreated short stature who had reached adult height, 20 were considered to have familial short stature, 8 constitutional delay of growth and puberty, 12 a combination of both conditions and 3 idiopathic short stature. Height predictions at various chronological ages were retrospectively compared to final adult height according to the Tanner-Whitehouse Mark I, Bayley-Pinneau and Roche-Wainer-Thisen methods. Heights were expressed as centimeters and standard deviation scores (SDS) and related to Tanner standardized curves. The final heights reached were below the target height (-2.0 (0.5) SDS vs. -1.6 (0.6), P<0.01). The three methods over-estimated adult height. The Bayley-Pinneau method was especially accurate in girls and in familial short stature. The Tanner and Bayley-Pinneau predictions were similar in constitutional delay of growth and puberty. The Roche method gave the greatest errors in all groups.
