What is the healthy weight for a 16yr old female who is 5foot 2inches?

Body Mass Index: For adults >20yo, we use body mass index (http://www.Cdc.Gov/healthyweight/assessing/bmi/adult_bmi/english_bmi_calculator/bmi_calculator.Html) to determine appropriate weight for height regardless of age & gender. For children, it's trickier as appropriate weight for height (bmi percentile) also depends upon age & gender. Check out http://apps.Nccd.Cdc.Gov/dnpabmi/ to enter your data: 92-134 lbs.
