AIM To investigate the difference of height development in children and adolescents in Xi'an and other developed countries, and the future growth trend of height for Xi'an children. METHODS Height medians for each group were estimated using λ median coefficient of variation (LMS) method. Height difference, yearly increment and crossing age of centile curve were compared between Xi'an, America and France children and adolescents for each sex. RESULTS Compared with children in America and France, urban children in Xi'an were higher before puberty, but shorter when they reached puberty and rural children and adolescents in Xi'an were shorter in all groups from 0 to18 years, and the height difference became greater after they had reached puberty. CONCLUSION Slower growth speed in puberty is mainly responsible for the shorter height of children in Xi'an by the time of puberty compared with those of developed countries, indicating that the nutrition of urban children in puberty, especially of rural children in Xi'an is not as good as that in developed countries.
