New Adult Height Predictor supports three ethnicities
The Bayley-Pinneau method for adult height prediction (AHP) from age, bone age and height was developed in 1952 based on American white children. In 2009, the method was modernised through the BoneXpert AHP based on automated bone age, better math and more recent Caucasian longitudinal studies.
We are proud to present now an extension of the method to cover three major ethnicities in the world: Caucasians, Asians and Africans.
This was possible through access to a longitudinal study of African children in Johannesburg, and a longitudinal study of Asian children in Japan.
The AHP is now based on version 3 of BoneXpert bone age, and for Caucasians it has been extended down to bone age 2 years.
For Caucasians, the difference between version 3 and the old AHP version is less than 1 cm in four out of five cases.
The new method is freely available online at the usual link – the old version can be reached with the button.
The new release is accompanied by a whitepaper describing the development and validation of the method.
