AnthroCalc

The AnthroCalc app calculates percentiles and Z-scores for length/height, weight, weight-for-length/height, body-mass index, and head circumference for typically growing children (using WHO or CDC references); for children with a number of syndromes (Turner, Down, Prader–Willi, Russell–Silver, Noonan and Klinefelter); and for preterm infants (using Fenton 2013 and 2025, INTERGROWTH-21st, or Olsen references). The app also performs specialized calculations of blood pressure (using NIH 2004 or AAP 2017 references), extended obesity measures, waist circumference, arm circumference, triceps and subscapular skinfolds, mid-parental/target height, predicted adult height, and height velocity for healthy children. Citations are provided for each reference range used for the calculations.
