【摘要】：目的制订青少年骨龄标准身高、体重和体重指数生长图表,为年龄推测时评价青少年基本发育状况提供参考。方法研究样本为2005年中国5城市抽取的3~19岁汉族正常青少年和儿童16570名(男8282,女8288)。应用RUS-CHN法评价受试者手腕部骨龄,由Box-Cox幂指数分布(Box-Cox power exponential distribution,BCPE)模型估价以骨龄分组的身高、体重和体重指数(Body mass index,BMI)百分位数。结果根据最小Akaike信息准测(Akaike Information Criterion,AIC)和广义AIC(Generalized AIC)选择了身高、体重和BMI BCPE模型μ,σ,ν,τ参数的自由度,依据BCPE模型所估价的百分位数曲线下样本例数的百分数与理论期望值相差在0.01%-1.21%之间。结论所选择的BCPE模型符合青少年儿童样本以骨龄分组的身高、体重和BMI数据的实际分布,所提出的生长图表可用于年龄推测中青少年基本生长发育状况的评价。
[Abstract]:Objective to develop a growth chart of standard height, weight and body mass index (BMI) for adolescents at bone age. Methods 16570 normal adolescents and children (male 8282, female 8288) were collected from 5 cities of China in 2005. The bone age of wrist was evaluated by RUS-CHN method. The height, body weight and body mass index (BMI) percentile of the bone age group were evaluated by the Box-Cox power exponent distribution power power exponential distribution model. Results the height was selected according to the minimum Akaike information to measure Akaike Information criteria on AICs and the generalized AIC(Generalized AICs. The degree of freedom of the body weight and the parameters 渭, 蟽, v, 蟿 of the BMI BCPE model, According to the percentile curve estimated by the BCPE model, the percentage difference between the sample number and the theoretical expectation was 0.01- 1.21%. Conclusion the BCPE model selected accords with the actual distribution of height, weight and BMI data of children and adolescents grouped by bone age. The growth chart presented in this paper can be used to evaluate the basic growth and development of adolescents in age conjecture.
