BMI百分位数解释

 
百分位数 <5: 体重偏轻
百分位数 >=5 以及 <85: 正常体重
百分位数 >=85 以及 <95: 超重
百分位数 >=95: 肥胖

 
 

 
注意
  • 在极端情况下(>97百分位数或<3百分位数),小的百分位数差异 表示有临床重要性的差异。在这些极端情况下,Z-评分能更准确地 反映测量值偏离平均值的程度,对于追踪变更是一个有用的工具。
  • 此计算器使用的 LMS 数据见以下数据表格.
  • 对于所有 LMS 表,表格中对应患者特定值的行见此表的第一 列;检索用于 Z-评分公式中 L(Box-Cox 幂)、M(中位数)和 S(广义 变异系数)的数值。
  • Z-评分可用于对 Z-评分正态表格百分位数 表中的对应百分位数进行表格搜索。表格左侧(Y 轴)的数字表示 Z 评分的个位和小数点后一 位数,而表格上方(X 轴)的数字表示 Z 评分小数点后两位数。

 
使用的方程式
 
年龄月 = 年龄 * 12
身体质量指数 = 体重 / (身高/100)2
Z 评分 = ((身体质量指数/M)L - 1) / (L * S)
百分位数 = Z对应百分位数(Z 评分)

 

 
示例
 
Z 评分~相应百分位数
+ 1.0~84
+ 2.0~97.5
+ 2.5~99.4
+ 3.0~99.7
