Percent of the population with inadequate iron intake

Definition

The percent of the population estimated to have inadequate iron intake from their diets. Estimates are based on modelled dietary intake data and do not include fortification or supplementation.

Relevance

Micronutrient deficiencies are among the most common forms of malnutrition and most of the global population has inadequate intake of at least one micronutrient. Iron is important for oxygen transport and energy production. Iron deficiency is the most common cause of anemia, leading to fatigue, impaired cognition, and adverse pregnancy outcomes. Estimates of inadequate intakes can help identify where interventions are needed to improve people’s health.

Additional Information

Estimates are based on modelled dietary intake of scarce data and assume equal caloric intake across countries. This leads to an underestimate of inadequate intakes in countries with lower caloric intake and an overestimate of inadequate intakes in countries with higher caloric intake.
