BMI percentile: In adults, we calculate body mass index but in children, we calculate BMI percentile (http://nccd.cdc.gov/dnpabmi/Calculator.aspx). 144# on 5'2" frame in 12yo female calculates to 96% percentile which is obese. However, BMI is only starting point for discussion. Can you believe that Dwayne 'The Rock' Johnson is technically obese? That's b/c much of his weight is muscle. Chat w/ur FamilyDoc or Ped.
