Growth Charts for Infants With Down Syndrome
Uses the Zemel 2015 growth charts for children with Down syndrome in the United States to report percentiles and Z-scores.
Includes weight, length, head circumference for age, as well as weight for length.
This calculator is for infants from 0 to 36 months of age. For children aged 2 to 20 years, there is a separate web calculator.
There are small differences in the calculations from the Zemel et al 2015 publication supplementary materials, likely due to rounding errors.
