Annual bone ages (Greulich and Pyle, GP) and BHI were, retrospectively, analysed in consecutive radiographs of the left hand (BoneXpert software) from GH therapy start (T0) up to 10 years (T10) thereafter, with T max indicating the individual time point of the last available radiograph. The results are presented as the median (25 %/75 % interquartile ranges, IQR) and statistical analyses were performed using non-parametric tests as appropriate.</jats:p> </jats:sec> <jats:sec id="j_jpem-2023-0084_abs_003"> <jats:title>Results</jats:title> <jats:p>The BHI standard deviation scores (SDS) were reduced (−0.97, −1.8/−0.3) as bone ages were retarded (−1.6 years, −2.31/−0.97) in all patients before start of GH and were significantly lower in patients with growth hormone deficiency (GHD) (−1.04, −1.85/−0.56; n=170) compared to non-GHD patients (−0.79, −1.56/−0.01; n=86; p=0.022). BHI SDS increased to −0.17 (−1/0.58) after 1 year of GH (T1, 0.5–1.49, p&lt;0.001) and to −0.20 (−1/−0.50, p&lt;0.001) after 5.3 years (T max, 3.45/7.25).</jats:p> </jats:sec> <jats:sec id="j_jpem-2023-0084_abs_004"> <jats:title>Conclusions</jats:title> <jats:p>BHI SDS are reduced in treatment-naive short-statured children regardless of their GH status, increase initially with GH treatment while plateauing thereafter, suggesting sustained improved bone health.</jats:p> </jats:sec>
