Boys with a simple delayed puberty reach their target height.
BACKGROUND
Final height in boys with delayed puberty is thought to be below target height. This conclusion, however, is based on studies that included patients with genetic short stature. We therefore studied final height in a group of 33 untreated boys with delayed puberty with a target height >-1.5 SDS.


METHODS
Standing height, sitting height, weight and arm span width were measured in each patient. Final height was predicted by the method of Greulich and Pyle using the tables of Bailey and Pinneau for retarded boys at their bone age (PAH1) and the tables of Bailey and Pinneau for average boys plus six months (PAH2).


RESULTS
Mean final height (175.8 +/- 6.5 cm) was appropriate for the mean target height (174.7 +/- 4.5 cm). The prediction method of Bailey and Pinneau overestimated the final height by 1.4 cm and the modified prediction method slightly underestimated the final height (-0.15 cm).


CONCLUSIONS
Boys with untreated delayed puberty reach a final height appropriate for their target height. Final height was best predicted by the method of Bailey and Pinneau using the tables for average boys at their bone age plus six months.
