mchtoolbox to calculate percentiles and z-scores for a child’s sex and age for BMI, weight, height, and head circumference based on CDC growth charts.
Reference data from nationally representative populations is used in maternal and child health research and public health surveillance to calculate percentiles, z-scores, and related values. This is important for measures that naturally change over the lifespan, such as body mass index and blood pressure. It can be difficult to calculate these variables and incorporate them into a tidy workflow because published code is often not available in the R language (or in any language), or in the same place. The motivation for this project is it create a package that contains functions compatible with the
tidyverse to calculate commonly used measures in maternal child health. We are also working on a shiny app for EDA and so that users can easily load a CSV and calculate these measures in the app.
cdc_growth() takes as input a data.frame with the following columns (units):
