采用SPSS软件快速构建儿童生长曲线

Fast construction of child growth curve by SPSS software

目的建立通过SPSS软件快速构建儿童生长曲线的方法。方法根据2005年中国九省市7岁以下儿童横断面调查获取的体格生长发育数据,应用SPSS软件计算17 721名上海市0-7岁儿童中男童年龄别体质量指标的均值、标准差以及第3百分位（P3）、第10百分位（P（10））、第50百分位（P（50））、第90百分位（P（90））和第97百分位（P（97））数值,通过软件曲线估计功能选择合适的多项式拟合模型;绘制体质量百分位数曲线,修改曲线的相关属性以实现曲线的最佳拟合效果,通过调用模板功能实现曲线叠加。结果应用SPSS软件,通过数据计算、曲线估计、曲线拟合、模板调用与曲线叠加等过程,成功构建了形态光滑、趋势一致的上海市0-7岁男童年龄别体质量的P3、P（10）、P（50）、P（90）、P（97）生长曲线。结论应用SPSS软件可快速构建儿童生长曲线,操作简单,实用性强,值得推广应用。

Objective To establish a method for fast construction of child growth curve by SPSS software. Methods The data of 17 721 children from Shanghai were extracted from the data base of a cross sectional survey of children aged 0 7 years old in nine regions of China in 2005. Then SPSS software was used to calculate the mean, standard deviation, the 3rd percentile （P3）, 10th percentile （P10）, 50th percentile （P50）, 90th percentile （P90） and 97th percentile （P97） of the boys, age specific body mass. The curve estimation function was used to select the appropriate fitting model and to draw the body mass centile curve. The property of curves was modified in order to achieve the best effect. The template invocation function was used to overlap the curves. Results Smooth and consistent growth curve of P3, P10, P50, P90 and P97 for children in Shanghai were constructed through data calculation, curve estimation, curve fitting, template invocation and curve overlapping by SPSS software. Conclusion SPSS software can be used for fast construction of children＇ s growth curves, and it has the advantages of convenient operation and good practicability, which makes it worthy of popularization.
