About The Study: Among 12- to 21-year-old U.S. females between 2003 and 2020, iron deficiency affected almost 40% and iron deficiency anemia affected 6%, with variation by the ferritin or hemoglobin thresholds used. Menstruation was a risk factor for both, but more than one-quarter of premenarchal individuals had iron deficiency.
