attach_HOMA: Homeostasis model assessment

In yikeshu0611/nhanesR: Tools for "NHANES" Database

Description

Homeostasis model assessment

Usage

attach_HOMA(
  data,
  years,
  IR = TRUE,
  IS = TRUE,
  beta = TRUE,
  fglu = FALSE,
  finsulin = FALSE
)

Arguments

data	data
years	years
IR	logical. whether to keep IR, insulin resistance
IS	logical. whether to keep IS, insulin sensitivity
beta	logical. whether to keep beta, function of beta cell function
fglu	logical. whether to keep fast glucose
finsulin	logical. whether to keep fast insulin

Details

• HOMA-IR: fglu(mmol/L) * finsulin(uU/mL) / 22.5

• HOMA-IS: 1/HOMA-IR

• HOMA-beta(%): 20 * finsulin(uU/mL) / (fglu(mmol/L)-3.5)
