よくある質問
Why is pediatric BMI different from adult BMI?
Children's body composition changes with age and differs by sex. Pediatric BMI is interpreted using age- and sex-specific percentile charts rather than fixed cutoffs.
What percentile is healthy for children?
A BMI between the 5th and 85th percentile is considered healthy. Below the 5th is underweight. Between 85th and 95th is overweight. At or above 95th is obese.
At what age should I use adult BMI?
Adult BMI categories apply from age 20 and older. For ages 2-19, use the pediatric BMI with percentile interpretation.
