detect_anaemia_u5: Determine haemoglobinaemia status for various population groups

Description

This set of functions identifies haemoglobinaemia in specific target groups such as children under 5 years (u5), children 5-11 years of age (5to11), children 12-14 years of age (12to14), non-pregnant women 15 years and above (np_women), pregnant women (pregnant), and men (men).

Usage

detect_anaemia_u5(hb = NULL, label = TRUE)
detect_anaemia_5to11(hb = NULL, label = TRUE)
detect_anaemia_12to14(hb = NULL, label = TRUE)
detect_anaemia_np_women(hb = NULL, label = TRUE)
detect_anaemia_pregnant(hb = NULL, label = TRUE)
detect_anaemia_men(hb = NULL, label = TRUE)
detect_anaemia(
  hb = NULL,
  group = c("u5", "5to11", "12to14", "np_women", "pregnant", "men"),
  label = TRUE
)

Value

If label is TRUE, a character value or character vector of haemoglobinaemia status classification (can be either "severe anaemia" or "moderate anaemia", "mild anaemia", or "no anaemia"). If label is FALSE, an integer value or integer vector of haemoglobinaemia status classification (0 = no anaemia; 1 = mild anaemia; 2 = moderate anaemia; 3 = severe anaemia)

Arguments

hb

A numeric value or numeric vector containing haemoglobin values in grams per litre (g/L).

label

Logical. Should labels be used to classify haemoglobinaemia? If TRUE (default), status is classified as "no anaemia", "mild anaemia", "moderate anaemia", or "severe anaemia". If FALSE, simple integer codes are returned: 0 for no anaemia; 1 for mild anaemia; 2 for moderate anaemia; 3 for severe anaemia.

group

A character value specifying the population target group to identify haemoglobinaemia from. Can be either one of u5, 5to11, 11to14, np_women, pregnant, or men. Default is u5.

Examples

x <- subset(mnData, age < 5)
detect_anaemia_u5(hb = x$hb * 10)
detect_anaemia_u5(hb = x$hb * 10, label = FALSE)
detect_anaemia(hb = x$hb * 10)
detect_anaemia(hb = x$hb * 10, label = FALSE)
