這是什麼

Body mass index is calculated from weight and height.[1,2]

為什麼重要

It is a simple body-size index that can connect population health, cardiometabolic risk context, body composition, and life-stage interpretation.[1,2]

它會影響哪些判斷

  • It is easy to compute and therefore widely used.[1,2]
  • It can connect to glucose, blood pressure, lipids, fatty liver context, and physical-function context.[1,2]

解讀陷阱

  • BMI does not directly measure body fat, muscle, fat distribution, fitness, or individual health.[1,2]
  • BioConst does not classify personal BMI or provide weight-loss advice.[1,2]
