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 calculating and determining select vitamin and mineral deficiencies
based on World Health Organization (WHO) guidelines found at
