Abstract
Background: In 2004, World Health Organization (WHO) recommended the use of serum ferritin as a primary indicator of iron deficiency. However, there was limited data on the magnitude and distribution of iron deficiency based on ferritin.
Objective: To describe the prevalence of iron deficiency as measured by serum/plasma ferritin in different regions of the world and its relationship with demographic and health indicators.
Methods: Data from the Biomarkers Reflecting Inflammation and Nutrition Determinants of Anemia and the WHO Vitamin and Mineral Nutrition Information System Micronutrients Database were used for this analysis. Unadjusted and inflammation-adjusted low ferritin prevalence were calculated for both databases. The prevalence of low ferritin among preschool children and non-pregnant women was examined according to its relationship with national gross domestic product (GDP), infant mortality rate (IMR), and anemia rate.
Results: In children, the median inflammation-adjusted prevalence of low ferritin was 35.3% (1st and 3rd quartiles: 17.5% and 48.1%). In non-pregnant women, the median inflammation-adjusted prevalence of low ferritin was 28.4% (1st and 3rd quartiles: 21.4% and 42.0%). For both children and women, the correlation between the prevalence of low ferritin and GDP, IMR, or anemia was consistently stronger using inflammation-adjusted prevalences than when using unadjusted prevalences.
Conclusions: The quartile values of low ferritin prevalence for children and non-pregnant women could be used to define the severity of ferritin as a public health problem.
