The AnthroCalcUK app uses the British 1990 Growth Reference and the LMS method to calculate percentiles and Z-scores for length/height weight body-mass index (BMI) head circumference sitting height leg length waist circumference percent body fat and blood pressure for typically growing children and youth ages birth to 23 years; and for length weight and head circumference for preterm infants born at 23 to 42 weeks gestation. Citations are provided for each reference range used for the calculations. Patient-specific data for length/height weight BMI and head circumference can be stored on the device for later retrieval and sharing.
