Iron Status of Women and Young Children in the United States (NHANES)
Iron Status of Toddlers, Non-pregnant, and Pregnant Women in the United States
Study Overview

Conditions
Detailed Description
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
