Standards of TW3 skeletal maturity for Chinese children.
This study included 17 401 normal Han urban children aged 1-20 years from five cities in China in 2005. The skeletal maturity scores were assessed by the Tanner-Whitehouse 3 (TW3) method, and the smoothed centiles curves of scores (TW3-Chinese RUS and TW3-Chinese Carpal) were calculated using the LMS method. The skeletal maturity of the Chinese is approximately the same as Europeans in childhood, but the extent of TW3-RUS skeletal maturity advance in puberty and the ages of complete maturity of TW-Carpals are evidently more advanced in the Chinese.
