micronutr: Determining Vitamin and Mineral Status of Populations

Vitamin and mineral deficiencies continue to be a significant public health problem. This is particularly critical in developing countries where deficiencies to vitamin A, iron, iodine, and other micronutrients lead to adverse health consequences. Cross-sectional surveys are helpful in answering questions related to the magnitude and distribution of deficiencies of selected vitamins and minerals.

This package provides tools for determining select vitamin and mineral deficiencies based on World Health Organization (WHO) guidelines found here.

What does micronutr do?

The micronutr package provides tools for determining select vitamin and mineral deficiencies using R. Currently, micronutr has functions for:

  • Detecting haemoglobinaemia or anaemia based on an individual’s serum haemoglobin level;

  • Detecting inflammation status based on c-reactive protein (CRP) and alpha(1)-acid-glycoprotein (AGP);

  • Detecting iron deficiency status based on an individual’s serum ferritin level;

  • Detecting iodine deficiency status based on a population’s mean urinary iodine concentration.

Installation

You can install micronutr from CRAN with:

install.packages("micronutr")

You can install the development version of micronutr from nutriverse r-universe with:

install.packages(
  "micronutr", 
  repos = c('https://nutriverse.r-universe.dev', 'https://cloud.r-project.org')
)

Usage

micronutr comes packaged with vignettes that show how to use the package for the purposes described above.
