【摘要】：研究目的：本研究通过对北京市儿童少年身体发育指标的分析,研究和探讨北京市儿童少年30年来的生长速度和生长水平变化,总结生长发育水平规律,制订适合我国现阶段的生长发育评价标准。为了解北京市儿童青少年生长发育状况、及早发现生长障碍儿童,以及生长障碍儿童的治疗效果观察提供敏感的数据支持,为促进我国青少年健康成长提供理论基础。研究对象和研究方法：本研究选取1981至1993年由国家体委组织的重点课题《儿童少年生长发育12年追踪研究》的北京城市户口受试者1216人,其中男471人,女513人。以及2009年～2010年在北京市海淀区城市户口小学和中学测得的2454名人员,其中男1231名,女1223名。测试身高、体重、胸围、坐高、拍摄手腕部X线片。利用中华05骨龄和G-P骨龄标准读取骨龄。数据处理为常规统计方法,独立样本T检验以及回归分析。结论： 130年间,北京市儿童少年的生长水平发生了很大改善,身高、体重、胸围等形态指标显著性增长。18岁组平均身高增加了男增加了4.5cm,女增加了2.2cm。生长发育继续提前,生长突增高峰年龄前移。30年来,身高生长长期趋势的增长方式是成年身高显著增长,说明我国身高生长长期趋势已经进入中期阶段,今后几十年将进入以成年身高为主的稳步增长阶段。 230年间,生长速度也有整体加速趋势,生长突增高峰年龄提前,生长突增高峰更高。 3作生长速度水平曲线时,分别作出早熟、晚熟、正常发育三种不同发育类型生长速度均值曲线或百分位数图,将峰龄重叠于同一轴上,算出均值和百分位数,作为评价个体儿童青春期发育水平的修正和补充依据,很有意义。 4制订现在儿童少年的生长水平曲线时,让断面数据和追踪数据的作回归分析,把追踪数据转换成符合现在现在生长水平的数据,绘制出光滑的曲线。
[Abstract]:Objective: to study and explore the changes of growth rate and level of Beijing children and adolescents in the past 30 years by analyzing the physical development index of Beijing children and adolescents, and to summarize the law of growth and development level. The evaluation standard of growth and development suitable for the present stage of our country was established. In order to understand the growth and development of children and adolescents in Beijing, to find out the children with growth disorders and to observe the therapeutic effect of children with growth disorders early, to provide sensitive data support, and to provide theoretical basis for promoting the healthy growth of adolescents in China. Subjects and methods: from 1981 to 1993, 1216 subjects (471 males and 513 females) were selected from Beijing urban hukou, which was organized by the State Sports Commission from 1981 to 1993, which was a key topic, "A 12-year Follow-up study on the growth and Development of Children and adolescents", in which 471 men and 513 women were enrolled in the study. And from 2009 to 2010 in Haidian District of Beijing City registered as a primary school and secondary school survey of 2454 people, including 1231 men, 1223 women. Test height, weight, chest circumference, sit height, and take X-ray of wrist. Bone age of 05 bone age and G-P bone age were used to read the bone age. The data were processed by routine statistical method, independent sample T test and regression analysis. Conclusion: during 130 years, the growth level of children and adolescents in Beijing has been greatly improved. The height, weight, chest circumference and other morphological indexes increased significantly. The average height of 18 years old group increased by 4.5 cm for males and 2.2 cm for females. In the past 30 years, the long-term trend of height growth is the significant increase of adult height, which indicates that the long-term trend of height growth in China has entered the middle stage. In the next few decades, we will enter a steady growth stage dominated by adult height. In 230 years, the growth rate has also shown an overall acceleration trend, and the peak age of growth sudden increase has been advanced. When the growth rate level curve was made, the mean growth rate curves or percentile maps of three different growth types, early maturing, late maturing and normal development, were made, and the peak ages were overlapped on the same axis. It is of great significance to calculate the mean and percentile values as the basis for revising and supplementing the level of puberty development of individual children. (4) when drawing up the growth level curve of children and adolescents today, Regression analysis of cross-section data and tracking data is made, and tracing data is converted into data in line with current growth level, and smooth curves are drawn.
