Abstract:

BACKGROUND: Different races, genders, heredity, geographical environment can cause different bone ages. Therefore, an assessment of hand-wrist bone age has been done in the Han and Uygur adolescents and children in Xinjiang region.
OBJECTIVE: To investigate the actual conditions of hand-wrist bone age in Han and Uygur adolescents and children in Urumqi.
METHODS: 760 children and adolescents (aged 4.0-4.0 years) of Uighur and Han nationalities were enrolled in this study. Two years acted as an age group. The hand-wrist bone age was estimated by hand-wrist X-ray using the Chinese Wrist Skeletal Development Standard CHN Method. The correlation between bone age and chronological age was analyzed statistically as well as difference in the bone age and chronological age between two ethnic groups.
RESULTS AND CONCLUSION: (1) A close correlation was found between hand-wrist bone age and chronological age for two ethnic groups (P < 0.05). (2) Thirteen age group showed higher bone ages than chronological ages, including four age groups of Han nationality girls aged 4.0-11.9 years, three age groups of Han nationality boys aged 4.0-9.9 years, three age groups of Uygur girls aged 4.0-9.9 years, and three age groups of Uygur boys aged 4.0-9.9 years. (3) The bone and chronological ages were higher in the Han girls aged 10-11.9 year than the Uygur girls aged 10-11.9 years as well as in the Han boys aged 12-13.9 years than the Uygur boys aged 12-13.9 years. Results show that the two ethnic groups of children and adolescents exhibit the early mature trend of skeletal development in multiple age groups; and there is a difference in skeletal and chronological age between Han and Uygur adolescents in some age groups.
