正畸临床用体重标准生长曲线的研究及绘制

目的：绘制乌鲁木齐地区学龄期青少年体重标准生长曲线及年增长量曲线，为正畸的临床诊断和矫正提供依据。方法：从1995年五部委(国家教委、卫生部等)进行的体质调查资料中获得5280名乌鲁木齐城乡7～18岁汉族中小学生的体重资料。绘制适合乌鲁木齐学生的正畸临床用体重标准生长曲线及年增长量曲线。结果：女生体重高峰期早于男生，前后相差约1年，高峰期跨度约为5年。无论城市或乡村，男、女生早期生长趋势较为一致，高峰期后体重有明显差距。城市女生体重略低于乡村女生。结论：标准体重生长曲线可用于判断青少年生长发育状态，为正畸诊断治疗提供科学依据。

Study and drawing of standard growth curve on body weitht of Urumqi Hans adolescent for orthodontics

Objective: To study and trace the standard growth curve of body weight of Urumqi Han's adolescent for orthodontic diagnosis and treatment planning. Methods: Statistical data were surveyed in 1995, which were obtained from subjects consisting of 5280 students aged from seven to eighteen years old in the city of Urumqi. Results: The mean values and the annual increment of body weight and the ages of the pubertal growth periods were analysed. The annual body weight increment peak was 13 years for girls and 14 years for boys. Under the pubertal growth periods, the annual increment of body weight was similar for both sexes. Above the pubertal growth periods, the annual increment of body weight of girls was slower than that of boys. Conclusions: The new standard growth curve on body weight plays an important role in the orthodontic diagnosis and treatment planning.
