Although the prevalence of iron deficiency anemia has decreased since the 1970s, it is still a concern for infants, children, women of childbearing age, pregnant women, certain ethnic groups, and low-income people.1-5
Data from a nationally representative study, the third National Health and Nutrition Examination Survey (2003-2006), showed that 9% of nonpregnant women between age 12 and 49 had iron deficiency anemia. This means approximately 8 to 10 million women in the United States may have IDA.3
The prevalence of IDA varies depending on the subset of the population discussed. For example, studies in the US and abroad have found IDA is more common among female military recruits than male recruits, and the rates are highest among black, non-Hispanic female recruits. These findings are consistent with national studies.6
