烟台市0～7岁儿童身高、体重和体质指数的探讨

目的:建立烟台市0~7岁青少年儿童年龄别身高(HFA)、年龄别体重(WFA)及年龄别体质指数(BMl)百分位标准及体质指数。方法:采用分层整群随机抽样法,收集烟台市0~7岁11747例儿童(男6261例,女5486例)、出生年月及2003~2005年身高和体重测量资料。应用LMS方法建立烟台市0~7岁儿童HFA、WFA和BMI百分位曲线。结果:运用LMS软件,分别获得0~7岁男女WFA、HFA和BMI百分位曲线各9条,为P3、P5、P10、P25、P50、P75、P90、P95和P97。烟台市男、女儿童的身高、体重随年龄增长不断增加,男、女儿童各年龄段P50年龄别身高百分位值与WHOP50比较无显著性差异。男童0~5岁的体重略高于WHO标准,但差距不大,5岁以后明显高于WHO;女孩在0~5岁与WHO标准基本接近。结论:应用LMS软件,获得了烟台市0~7岁儿童身高、体重和BMI百分位参考值。

Study on growth references of height, weight and body mass index for children aged 0～7 years in Yantai

Objective:To establish the percentile standards of growth references of height for age (HFA),weight for age (WFA),body mass index (BMI) and for Children 0~7 years inYantai.Methods:Randomized stratified clustered sampling method was used. The data of height and weight of 11 747 children (6 261 boys,54 861 girls) from 2003 to 2005 inYantai were collected to establish HFA, WFA and BMI percentile curve of the child at 0~7 years age in Yantai with LMS method.Results:Nine percentile curves of the 0~7 years child were plotted for HFA, WFA and BMI respectively.They were percentile P3,P5,P10,P25,P50,P75,P90,P95 and P97 of HFA, WFA and BMI. Weight and height of child increased constantly with ages in Yantai. Comparison with WHO the P50, P50 of the male and female child at various ages section, the percentile of age for height had no significant difference,but was slightly higher than WHOP50 standard. The weights of boys aged 0~5 from Yantai were higher than the WHO standard slightly,but that aged over 5 obviously were higher than WHO's, while that of girls aged 0~5 basically approached WHO's.Conclusion:The percentil references of height,weight and BMI of the children aged 0~18 in Yantai have been developed by LMS software.
