There are two main approaches to assessing micronutrient malnutrition in emergencies.
1. Indirect assessment involves the estimation of nutrient intakes at a population level and
extrapolating from this the risk of deficiency and the likely prevalence of micronutrient
deficiency disease.
2. Direct assessment involves the measurement of actual clinical or sub-clinical deficiency in
individuals and then using that information to give a population estimate of the prevalence of
the micronutrient deficiency disease.
The indirect assessment approach involves two stages. First, measuring or estimating the
dietary intake of the population and, second, comparing this intake with the nutrient
requirements of the population.
Direct assessment of micronutrient deficiencies can use clinical signs and symptoms and/or
biochemical testing to diagnosis the presence of micronutrient malnutrition. These detection
methods can be combined with survey techniques to generate an estimate of the population
prevalence (rate) of micronutrient malnutrition.
