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. 

Authors: Angela C. Weyand, M.D., of the University of Michigan Medical School in Ann Arbor, is the corresponding author.
