NWS-22 Reduce iron deficiency among pregnant females
National Data Source
National Health and Nutrition Examination Survey (NHANES)
; Centers for Disease Control and Prevention, National Center for Health Statistics (CDC/NCHS)
Changed Since the Healthy People 2020 Launch
10 percent improvement
Number of pregnant women with body iron less than 0 where body iron is defined as follows: Body iron (mg/kg) = -[log10 (sTfR X1000/ferritin)-2.8229]/0.1207 Where sTfr is serum transferring receptor in milligrams per liter and ferritin is serum ferritin in micrograms per liter

Data Collection Frequency
Comparable Healthy People 2010 Objective
Retained from HP2010 objective
Caveats and Limitations
Iron deficiency status varies by trimester. Future analyses of overall prevalence of iron deficiency will need to standardize to the trimester distribution in 2003-2006 NHANES.
