摘要
目的探讨不同软件对生长曲线偏度系数-中位数-变异系数(LMS)法的实现方法,优选适合基层使用的统计方法。方法使用包头市定期体检正常婴儿的3、6、9和12月龄头围数据,分别应用SAS、R、STATA和SPSS软件包进行生长曲线的LMS拟合,并从方便程度、难易程度、界面、结果展示及更新维护等4个方面对几种软件的使用效果进行评价。结果使用不同软件分别实现了生长曲线LMS的计算和绘图,绘制的包头市婴儿的头围生长曲线的各百分位数值结果一致。从操作步骤、难易程度、操作界面、操作选项、更新维护、软件成本和结果展示来看,R软件更具优势。结论在常用生长曲线LMS的计算和绘图方面,与SAS、STATA和SPSS软件相比,R软件综合了各软件的优点,比较适于基层妇幼保健工作者使用。
Objective To explore the methods to realize the growth curve fitting of coefficients of skewness-median-coefficient of variation( LMS) using different software,and to optimize growth curve statistical method for grass-root child and adolescent staffs.Methods Regular physical examination data of head circumference for normal infants aging 3,6,9 and 12 months in Baotou City were analyzed. Statistical software such as SAS,R,STATA and SPSS were used to fit the LMS growth curve and the results were evaluated upon the user 's convenience,study circle,user interface,results display forms,software update and maintenance and so on. Results Growth curve fitting results showed the same calculation outcome and each of statistical software had its own advantages and disadvantages. With all the evaluation aspects in consideration,R software excelled others in LMS growth curve fitting. Conclusion R software have the advantage over other software in grass roots child and adolescent staff.
