Description

This function traverses the decision tree of the "JGZ-Richtlijn overgewicht 2012" and "JGZ-Richtlijn Ondergewicht 2019"

Usage

calculate_advice_wgt(
  sex = NA_character_,
  ga = NA,
  etn = NA,
  dom = NA_integer_,
  y = NA,
  dom_hgt = NA_integer_,
  hgt = NA,
  dob = NA_character_,
  test_gain = TRUE,
  y1 = NA,
  y0 = NA,
  hgt1 = NA,
  hgt0 = NA,
  dom1 = NA_integer_,
  dom0 = NA_integer_,
  verbose = FALSE
)

Arguments

sex	Character, either "male" or "female"
ga	Gestational age, completed weeks (Integer or character)
etn	Etnicity, one of "NL" (dutch), "TU" (turkish), "MA" (moroccan) or "HS" (hindustani). Currently not functional, always uses "NL". Only used for target height.
dom	Vector with dates of measurements. Either supplied as age in decimal years or a date in the format yyyymmdd.
y	Vector with height measurements (cm)
dom_hgt	Vector with date of measurement relating to height. Either supplied as age in decimal years or a date in the format yyyymmdd.
hgt	Vector with height measurements (cm)
dob	Date of birth (yyyymmdd). Required if dom is supplied as a date string.
test_gain	Logical. Should the increase or decrease in Z-scores be tested? The default is TRUE.
y1	Legacy parameter.
y0	Legacy parameter.
hgt1	Legacy parameter.
hgt0	Legacy parameter.
dom1	Legacy parameter.
dom0	Legacy parameter.
verbose	Set to TRUE to obtain warnings on reference finding.

Details

The decision tree assesses both single and paired measurements. The observation corresponding to the oldest age is taken is the current measurement.
