Summary
Published by the Micronutrient Forum and GAIN in 2022, this report presents updated global modelling estimates of hidden hunger — the inadequate intake or absorption of essential vitamins and minerals. It disaggregates deficiency burdens by micronutrient, geography, and demographic group, providing a revised evidence base for targeting nutrition interventions. The estimates are intended to support policymakers, donors, and programme implementers in prioritising micronutrient-sensitive strategies.
UK applicability
As a global-scope report, its direct applicability to the UK is limited; however, the methodological frameworks and regional benchmarks may inform UK overseas development policy, global health commitments, and the work of UK-based nutrition agencies operating internationally.
Key measures
Prevalence of micronutrient deficiencies (%) by region, country, and population group (children, women of reproductive age); estimates of populations affected (millions)
Outcomes reported
The report estimates the prevalence of key micronutrient deficiencies — including iron, zinc, vitamin A, and iodine — across regions and population groups worldwide. It quantifies the scale of hidden hunger to inform nutrition policy and programmatic investment.
