Iron Status of Women and Young Children in the United States
Iron Status of Women and Young Children in the United States
This analysis describes the distribution of TBI and the prevalence of iron deficiency (ID)
 and iron deficiency anemia (IDA) among toddlers, non-pregnant women, and pregnant women.
Background: Total body iron stores (TBI), which are calculated from serum ferritin (SF) and
 soluble transferrin receptor (sTfR) concentrations, can be used to assess the iron status of
 populations in the United States.

 Objective: This analysis describes the distribution of TBI and the prevalence of iron
 deficiency (ID) and iron deficiency anemia (IDA) among toddlers, non-pregnant women, and
 pregnant women.

 Design: Investigators analyzed data from NHANES; toddlers aged 12-23 mo (NHANES 2003-2010),
 non-pregnant women aged 15-49 y (NHANES 2007-2010), and pregnant women aged 12-49 y (NHANES
 1999-2010). Investigators used SAS survey procedures to plot distributions of TBI and produce
 prevalence estimates of ID and IDA for each target population. All analyses were weighted to
 account for the complex survey design
Included:

 -  Children ages 12-23 months and Women ages 12-49 years

 -  Those who completed the MEC

 Excluded:

 - Those missing data on iron biomarkers
