September 2020: New bone age reference curves from Taiwan
A new independent study has been published with bone age reference curves for healthy Taiwanese children.
The paper is from Kaohsiung Medical University Hospital and published by Wiley: https://onlinelibrary.wiley.com/doi/epdf/10.1002/kjm2.12268
The study showed (see graph above) that Taiwanese children are slightly delayed relative to the GP standard below the age of 8, while they are markedly advanced above the age of 13, by typically one year.
This is in good agreement with the results for Asians in a previous study of four ethnicities from Los Angeles, shown below (link to abstract).
