NWS-21.2 Reduce iron deficiency among children aged 3 to 4 years
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
Maintain consistency with national programs, regulations, policies, and laws.
Number of children aged 3 to 4 years 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
Number of children aged 3 to 4 years
Data Collection Frequency
Comparable Healthy People 2010 Objective
Adapted from HP2010 objective
Changes Between HP2010 and HP2020
This objective differs from Healthy People 2010 objective 19-12a in that the model used to determine iron deficiency was changed from the ferritin model to the body iron stores model.
