W／H、W／H^2和W／H^3三种指数法评价儿童、青少年肥胖的比较

THE COMPARISON AMONG W/H,W/H^2 AND W/H^3 IN ESTIMATING OBESITY IN CHILDHOOD AND ADOLESCENCE

通过对２４４８名７～１８岁儿童、青少年身高和体重的调查，研究了Ｗ／Ｈ、Ｗ／Ｈ~２和Ｗ／Ｈ~３三个指数与儿童、青少年身高、体重的关系。结果表明，在三个指数中，Ｗ／Ｈ~２与身高相关性最小，与体重的相关系数仅次于Ｗ／Ｈ，Ｗ／Ｈ~２似更适合作为评价儿童肥胖的指数。而不同年龄性别儿童、青少年的Ｗ／Ｈ~２指数应不尽相同。

The study examined several weight for height indices-W/H,W/H2 and W/H3-for their suitableness in estimating obesity in childhood and adolescence. Data were obtained from a sample of 2448 children and adolescents aged 7-18 residing in Hefei. The results showed that as compared with W/H and W/H3, W/H2 was highly correlated with weight and lower with height. It suggested that W/H2 was the most useful index in estimating obesity in childhood and adolescence. The estimating standards of obesity were made, depending on the percentiles of W/H2 by sex and age.
