Revealing the Prevalence of "Hidden Hunger" (December 2022)

The presentation was given at the 22nd IUNS-ICN International Congress of Nutrition in Tokyo, Japan, in December 2022. The document discusses the prevalence of hidden hunger or micronutrient deficiencies, particularly among preschool-aged children and women of reproductive age, using data from 22 countries from 2003-2019. It outlines the approach used to estimate the prevalence of single and combined micronutrient deficiencies, including the use of biomarkers, cutoffs, and inflammation adjustments. The presentation also provides estimates of global and regional prevalence of micronutrient deficiencies.
