上海市儿童青少年肺功能百分位数参考值

建立符合上海市儿童青少年生长发育特点的肺活量参考值及曲线,为监测本地区儿童青少年功能水平变化提供参照.方法 以2014年上海市学生体质与健康调研6区15 421名7~18岁学生为样本,用偏度中位数—变异系数(LMS)法建立年龄别肺活量百分位数值及曲线.结果 随着年龄增长,男、女生肺活量呈上升趋势,在12岁之前差异不大,12岁之后差异逐渐增大,各年龄组均为男生高于女生(P值均<0.01).2014年上海市中小学生肺活量百分位数曲线随年龄增加呈增长趋势,各年龄组均高于全国同期水平,上海市儿童青少年肺活量百分位数存在性别差异.结论 儿童青少年肺活量百分位数曲线图为上海市儿童青少年功能水平测量提供了一种直观评价方式.

Percentile reference for vital capacity among children and adolescents in Shanghai

Objective To establish norm and curves for vital capacity among children and adolescents in Shanghai,and to provide basis for lung function surveillance.Methods Data were obtained from cross-sectional surveys among 15 421 school children form 6 districts in 2014,using LMS method to establish the percentile reference and curves.Results It showed an increasing trend with age,boys and girls lung capacity showed an upuard trend.Before 12 years old,the difference was not big,affer 12 years old,the difference increases gradually.with boys higher than girls(P<0.01).Average vital capacity among children in Shanghai was higher than national level(P<0.01).There is significant sex difference in vital capacity among children and adolescents in Shanghai.Conclusion Percentile curves established in this study provides an intuitive evaluation method for the functional measurement.
