“…Similar results were also found when comparing Chinese with British (Dangour et al, 2002). These comparisons suggest that the difference in stature between Chinese and European children may be attributed to LL and also indicate that the plateauing age for LL is earlier in Chinese, which is consistent with reports on bone maturation that show earlier ages of hand and wrist skeletal maturity of Chinese children compared to the TW3 standards based on European and North American children (Ashizawa et al, 2005;Zhang et al, 2008). Figure 6 indicates that SH/LL of Chinese children aged older than 2 years was significantly larger than that of Dutch (Fredriks et al, 2005), Austrian (Gleiss et al, 2013) and Mozambican (Padez et al, 2009) children.…”

“…The most striking aspect is that, at the end of puberty, the average BA − CA has reached approximately 1 year. In other words, Chinese children reach maturity around one year earlier than the children that made up the GP BA reference, in agreement with previous studies [12]. This dramatic deviation was the main motivation for setting up the BX-China05 BA scale.…”

Rationale and Objective. Large studies have previously been performed to set up a Chinese bone age reference, but it has been difficult to compare the maturation of Chinese children with populations elsewhere due to the potential variability between raters in different parts of the world. We re-analysed the radiographs from a large study of normal Chinese children using an automated bone age rating method to establish a Chinese bone age reference, and to compare the tempo of maturation in the Chinese with other populations. Materials and Methods. X-rays from 2883 boys and 3143 girls aged 2–20 years from five Chinese cities, taken in 2005, were evaluated using the BoneXpert automated method. Results. Chinese children reached full maturity at the same age as previously studied Asian children from Los Angeles, but 0.6 years earlier than Caucasian children in Los Angeles. The Greulich-Pyle bone age method was adapted to the Chinese population creating a new bone age scale BX-China05. The standard deviation between BX-China05 and chronologic age was 1.01 years in boys aged 8–14, and 1.08 years in girls aged 7–12. Conclusion. By eliminating rater variability, the automated method provides a reliable and efficient standard for bone age determination in China.

“…Similar studies have been performed for the TW method on North American [169], Austrian [162], English [170,171], Brazilian [172], Korean [173], Chinese [174][175][176][177], Japanese [178][179][180]188], Belgian [181], Danish [182], Mexican [183], Indian [184], Portuguese [185], Australian [186], even Hottentot populations [187], with similar conclusions.…”
