In InsightRX/clinPK: Clinical Pharmacokinetics Toolkit

Median growth values for infants and children

Description

Calculate median weight, height, and BMI for age/height for infants and children using CDC Growth Charts data and equations.

Usage

median_weight_for_age(
  age,
  age_units = c("years", "months", "weeks", "days"),
  sex
)

median_height_for_age(
  age,
  age_units = c("years", "months", "weeks", "days"),
  sex
)

median_bmi_for_age(age, age_units = c("years", "months", "weeks", "days"), sex)

median_weight_for_height(
  height,
  height_units = c("centimetres", "metres", "feet", "inches"),
  sex,
  population = c("infants", "children")
)

Arguments

age	A numeric vector of ages in the unit specified in age_units.
age_units	A character string specifying the units of all age values.
sex	A character vector specifying patient sex. Either "male" or "female".
height	A numeric vector of heights in the unit specified in height_units.
height_units	A character string specifying the units of all height values.
population	A character string specifying the population table to use for median_weight_for_height(). Either "infants" (birth to 36 months) or "children" (2 to 20 years).

Value

A numeric vector of median weight, height, or BMI values for the given ages/heights.
